soloz2 Posted May 31, 2011 Share Posted May 31, 2011 I posted in the 4th gen forums and didn't get anywhere so I thought I might get more response here since this seems to be a 2.5i thing. My intake has filter material after the panel filter that appears to not be removable without some modification. I'm curious what this is for and if there would be any adverse side effects by removing it. At a minimum the filter looks like it could use a good cleaning.

burnout8488 Posted May 31, 2011 Share Posted May 31, 2011 Whoa! Is your car is a PZEV model? I've never seen that before. If you've got a high flow filter, I'd probably keep the pre-filter. Link to comment Share on other sites More sharing options...
soloz2 Posted May 31, 2011 Author Share Posted May 31, 2011 Idk. There was never any badging or anything like that to indicate?

burnout8488 Posted May 31, 2011 Share Posted May 31, 2011 One way to check is to see if you have 3 catalytic converters in a crazy "Y" shape header....I think. Link to comment Share on other sites More sharing options...
soloz2 Posted June 1, 2011 Author Share Posted June 1, 2011 Anyone have a pic of a regular 2.5i exhaust so I can compare?

soloz2 Posted June 1, 2011 Author Share Posted June 1, 2011 In the first pic the header on the right looks like what I have. PITA to get to the filter if the exhaust is hot... I thought that's how all 2.5i exhausts looked?

burnout8488 Posted June 1, 2011 Share Posted June 1, 2011 That's just the normal '06-'09 header, so you're not PZEV then. Really wonder why you've got that pre-filter! Any other members have it?? Link to comment Share on other sites More sharing options...

soloz2 Posted June 1, 2011 Author Share Posted June 1, 2011 I'll have to crawl under the car to look at the header. I never really paid much attention and it looked like the pics I've seen so I didn't look any more closely.

soloz2 Posted June 2, 2011 Author Share Posted June 2, 2011 It may be a couple days. I'm working late every day this week. I'll try and snap a couple pics. Maybe I'll be lazy and see if putting my camera under the car will yield a decent pic...

scottyjneilson Posted June 2, 2011 Share Posted June 2, 2011 so potentially we could just pull it? right ? since you guys dont have one we should be fine running withough one as well...? Link to comment Share on other sites More sharing options...
burnout8488 Posted June 3, 2011 Share Posted June 3, 2011 I spose so, the air filter does a good enough job on our cars without it I guess! Link to comment Share on other sites More sharing options...
milesej05 Posted June 3, 2011 Share Posted June 3, 2011 IMO, I think it would just hurt performance. Case in point, if your air filter was in the open (such as an aftermarket RAI) then I could see the use for it in the spring time with the pollen or if it was mounted in your fenderwell. But since we have this cool air box thing, I think you will be perfectly fine without it. just my .02 Link to comment Share on other sites More sharing options...
