hey guys, im just wondering if anyone has really had a problems with this?

i dont think that this would change the exhaust temp so drastically that the cats would not work and cause the car the fail the emissions test.

any answers?

thanks,
jeremy

PS my plugs are autolite 104s @ 40

 

well ur front o2s are heated 02s and they start to work at a certain temperature

if ur car does not warm up to a certain temperature the the 02s in teh front will not go into what they call "ready state" and u will fail ,
but my car doesnt haveteh fans reprogrammed so if its hott outside or been drvien hard or for a while teh temp with do what it normally does, but stays cool while cruising ,

as for teh cold plugs i do not know
