manowar77 Posted January 17, 2010 Report Share Posted January 17, 2010 I was just checking out some stuff on ebay and noticed customized air filters from Insys that fits for example STS 1995! Easy to install it says also..i was wondering if when you have this filter installed,does it open up more room around where the original air intake box were placed? I usually remove the air filter box to gain access to the lower radiator hose clamp when changing coolant...but with this customized air filter i wonder if you can get to the lower hose clamp without removing the filter? Looks cool also Roger Roger Martinsen Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted January 17, 2010 Report Share Posted January 17, 2010 Hi Roger, Yes, it would provide more room than the factory air box, but I am uncertain if enough room to work with it in place. Link to Insys ebay items: http://motors.shop.ebay.com/insys-usa/m.ht...=&_osacat=0 In my tests with a cone filter in my Northstar in the 96 STS I did not find a setup that was advantageous over the stock setup. When Greg did back to back dyno tests using a cone filter type intake on his 4L Aurora he did see an increase in the dyno. I would be interested in seeing an instrumented test on this intake. regards, bruce Bruce 2016 Cadillac ATS-V gray/black Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
manowar77 Posted January 18, 2010 Author Report Share Posted January 18, 2010 I emailed Insys about this air intake and it doesnt fit on STS 1995, it doesnt have the fittings for the IAT sensor or for the crank hose connection! Too bad...looked nice! Roger Roger Martinsen Link to comment Share on other sites More sharing options...
manowar77 Posted January 19, 2010 Author Report Share Posted January 19, 2010 Found another air intake on Ebay from eautotuning that according to the seller has fittings for the IAT sensor and if equipped crank case hose! I cant remember if the stock air intake on my STS 1995 has a crank hose on it...do anyone of you guys know if it does have that? They need to put an additional fit for this hose in that case! Do the STS 1995 have a crank case hose on the stock air intake? Best regards Roger Roger Martinsen Link to comment Share on other sites More sharing options...
Chris_Austria Posted January 20, 2010 Report Share Posted January 20, 2010 I think these kind of air filters won't increase the power of the engine.. The main problem would be that it is "breathing" the hot air produced by the engine... You would have to seal the filter up and give it a cold air intake. For example something like this that would build a "wall" between the eninge area and the air intake area: Link to comment Share on other sites More sharing options...
manowar77 Posted February 5, 2010 Author Report Share Posted February 5, 2010 Installed one from Eautotuning that i bought on Ebay, fits right on with connections to the Iat sensor and crank hose! Looks nice also! Roger Martinsen Link to comment Share on other sites More sharing options...

Chris_Austria Posted February 5, 2010 Report Share Posted February 5, 2010 I would be afraid of losing power caused by hot air. Is there at least a cold air flow into the filters direction? How does it sound with the open filter? Link to comment Share on other sites More sharing options...
manowar77 Posted February 5, 2010 Author Report Share Posted February 5, 2010 Yes, it sucks cold air from the stock intake hole so i dont think that loosing power will be a problem,the sound are about the same as before...maybe a little more "throaty"!

Chris_Austria Posted February 5, 2010 Report Share Posted February 5, 2010 The problem is that the cold air flow is not as efficient as before, when the intake was a closed system and the hot air around was held out. Why did you change to this kind of air filter? Link to comment Share on other sites More sharing options...
manowar77 Posted February 5, 2010 Author Report Share Posted February 5, 2010 I changed to this filter because its smaller then the stock air filter and it opens up more room in the engine room, now i dont have to remove the stock intake to gain access to the lower radiator hose when changing coolant..also looks nice i think! The filter is reusable after washing it also! Roger Martinsen Link to comment Share on other sites More sharing options...
CarlaValentine Posted February 5, 2010 Report Share Posted February 5, 2010 My brother wants to do something similar to this with my Caddy. He says when I rev the engine he can hear it saying "MORE!" and thinks I should put a different air intake on it. After doing some searching on the topic, I think the stock setup seems to be best suited for the car. If I were to go ahead with the cone filter or something similar, I would take Chris' idea of putting a "wall" around it to shield it from warm engine air, and direct cold air flow to it. For now I think I'm going to stick with the original setup. I don't really see anything wrong with it except that it takes up a lot of space. Just my 2 cents.

BodybyFisher Posted February 5, 2010 Report Share Posted February 5, 2010 I agree with the hot under hood air, its not a problem at highway speed ramming air through it, its going to be a problem in stop and go, it may feel piggy then. We have had extensive conversations about this, there is much to be lost and not much to be gained by doing this. Keep in mind that we had the guru here who designed the Northstar, he once made a statement that "all of the low hanging fruit has already been picked". He said that the stock air box setup was more than adequate and the BIG bottle neck was the front to rear exhaust crossover and the exhaust system... where if changed might yield some performance gains. Keep in mind that these 279 cu inch engines are putting out 1 HP per cu inch already. The worst in my opinion to be lost by a setup like this, is the ram air cooling of the PCM, if your PCM is located below the air box as it is in my 96 Deville. The TB pulls air over the PCM to cool it. The PCM might not be located under the air box in 1994/1995, it might be under the dash on the passenger side. The processor and capacity of the PCM was increased in 1996, so that might be why they wanted better cooling. More NOISE does not equate to added performance, as a matter of fact it might reduce performance.

manowar77 Posted February 5, 2010 Author Report Share Posted February 5, 2010 I still have the stock intake left so if it doesnt work with this cone filter i will replace it with the stock intake as it were from the beginning!

Chris_Austria Posted February 5, 2010 Report Share Posted February 5, 2010 I have some experience with this kind of filters on other cars. No one had more power or better fuel economy. That it is washable is nice, but a "normal" not washable filter is very very cheap. And to wash these filters you need a cleaning kit, that costs more than a normal filter. Also you can kill your air flow sensor with these filters, especially if you add too much oil (they anyway have more than a normal filter). That's not a cheap repair! I also had a Carbon Airbox... With this system the sound was much better and I think the performance was a little bit increased. The cold air is directly sucked in to the filter housing and after that into the enigne, because of the construction the air is often even cooler than with the original system. This is a picture of the BMC Carbon Airbox: Link to comment Share on other sites More sharing options...

NOISE does not equate to added performance I can for sure see where there is room for improvement on the exhaust. While under my car doing an oil change, I noticed that the exhaust coming from the manifold down actually flattens out to what appears to be about an inch or so thick, and doesn't get any wider to make up for it. It seems like that would be very restricting on the exhaust flow, and the only reason I can see for it being like that is because it's the only way it would fit where it's routed. I don't think there is much that can be done about that given the confinement of space. New mufflers are definitely a good possibility for me in the spring/summer. Does anyone know what effect it would have to "hollow out" the catalytic converter? Not that I plan to, I'm just wondering. I definitely agree whole-heartedly that noise does not equal performance, but it is nice to hear the tone of a powerful engine. Link to comment Share on other sites More sharing options...
BodybyFisher Posted February 5, 2010 Report Share Posted February 5, 2010 I found this posting in defense of one of the filters suspected of causing MAF sensor problems to be simplistic if not idotic in its defense. One of the defenses was that the MAF is located in the intake SO THERE!!! and oil from other sources can also get on your MAF... haha.... ours is in the air stream..... and um, oil streaming off a filter at those air speeds will be air borne, I dont even think thats an matter of question, but to make this argument to me comes from a very weak position, and makes me crack up.. "and held a grease covered napkin out the window, the oil wouldn't come off-trust me" GREASE COVERED??, we are talking OIL here, , oil that is on a screen with air forced through it HUH?

BodybyFisher Posted February 5, 2010 Report Share Posted February 5, 2010 The CAT is there for a reason, if you hollow it out, it will not do its job. In my year (96) I have pre-and post O2 sensors along with one in each manifold for a total of 4 O2 sensors. The pre and post O2 sensors monitor the CATs performance, if the CAT is not performing it will set a P code. Since you live in New York state that fails vehicles for P codes, your vehicle would fail. In addition, I am not sure how getting a CAT performance code would affect the fuel management system, it may richen up or lean out the mixture to compensate and harm fuel efficiency or lean the engine out so to cause detonation which the PCM would recongnize and prompty RETARD your ignition hurting performance. The ideas that todays youth come up with that make more noise, done for appearances purposes, trying to sound meaner or bigger or more powerful, where they think they are also improving performance are humorous, uninformed and driven by marketing and popular culture. If you want noise and you want to look GANGSTA, or you want to draw attention to yourself, hell yea, you can do whatever you'd like, hell put maxwell house coffee cans on the exhaust outlets and put hollowed out GLASS PACK CHERRY BOMB mufflers on it, to DRAW attention to yourselves. Hell put SIDEPIPES on it, and run it back to the manifolds and RAM AIR HOOD SCOOPS and rip out all of the interior to LIGHTEN IT. We are driving Cadillacs here folks, we CRUSH most vehicles out there sitting in comfort with the AC on, we get 1HP per CU IN. We are not driving hondas here, they do all of the crazy mods to look and sound bigger, we crush them with growling power STOCK Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
Chris_Austria Posted February 5, 2010 Report Share Posted February 5, 2010 When using quality washable filters like K&N or BMC it is for sure needed to be oiled. There are cleaning kits available that contain a washer fluid and the oil. Be carefull when it's time for cleaning (30.000km are the common washing intervall of such filters that I've owned) Link to comment Share on other sites More sharing options...

I would never do that to my car, really, I wouldn't. That's not AT ALL what I am going for. I would also never hollow out the Cat on my car. I was simply wondering what, if any, effect it would have. I know mine only has 2 O2 sensors, but I'm not sure where they are. Doesn't matter, like I said, I don't plan on altering my Cat. Just the mufflers maybe. I may fall into the category of "today's youth" but even I find a lot of their/our ideas pretty stupid. Link to comment Share on other sites More sharing options...

According to Bruce's instrumentation, my DTS is putting out around 330 HP. That agrees perfectly with the guy that tuned it. His instrumentation also said around 330 HP. So... I have a little OVER 1HP per cubic inch. I really shouldn't say this...I know it makes them feel bad, and I am usually a pretty nice guy...but....
