JIMDTS Posted June 9, 2005 Report Share Posted June 9, 2005 When I was at the dealer when my engine was torn down, I noticed the plugs were Denso brand I asked the mechanic about them He mentioned they were originals back in 01. So they still had plenty of life left in them at 42k and I didn't bother having them replaced,. And I thought GM only used Delco..The Local cheap Auto parts(Murrays) & (Auto Zone) didn't have any delco's in stock for my car so I just gaffed it off Just struck me as odd that Denso's were used.
