Does anyone have the brand and numbers for a 2004 air filter or do you have to go to the Chevy dealer ??
Spectre make a drop in filter that is like a K&N , it is an oiled filter. The cost is about one quarter of a K&N filter and reportedly performs as well or better. I have used a Spectre filter for two years now in my supercharged 04 with no problems. I don’t know if they make a dry filter.There is a filter like k&n but it’s a dry filter no oil
You are spot on, Bruce. I installed mine knowing that it would not improve performance any more than my caliper covers would improve braking. It just gives me that "hot damn" feeling whenever I lift the hood, and after all, that's all I ask of it.I don't believe the K&N system or others of that ilk can pass more cool air than the stock straight shot design, with the right filter. They do however, look cool as hell and dress the under-hood up a lot. I'd put them in the same category as the floor gage pod, looks great but not very beneficial. It's a personal choice, if it blows your skirt up go for it.
