Air Charger for 2004 CTS 3.6L

[Bruce Nunnally]

The K&N aircharger p/n for the 3.6L CTS is/will be Aircharger 63-1091

The Aircharger is K&N's name for a component that replaces the airbox and filter, while providing some heat isolation.

The 3.6L piece may look similar top the one for the 3.2L, pictured here, which runs around US$250 street prices:

This note in from K&N on their test process:

Dear Bruce,

Here is a link to our web site for the dyno test for the FIPK kits

http://www.knfilters.com/FIPK/fipkinstr.htm

If the dyno test for you vehicle is not available yet please check back

at a later date. We at K&N use 3-5 different cars when doing dyno

testing. We feel this will give a more accurate dyno reading, than using

just one car and doing 3-5 dyno runs. The disadvantage in doing it this

way is it can take considerably more time to find 3-5 cars in our local

area to test, but the results are much more accurate.

Thanks for writing

K&N Customer Service

looks like that page has some dyno results for some filters, but nothing recent.
