Didn't know where else to post this but, has anyone taken the foam off? What are the benefits? Are there any bad things about it? If it matters i have a '12 LS with the 1.8 auto of course. And I already did the Intake Resonator mod.

My Wix filter has one too. I believe it's just another layer of restriction to improve economy. I don't think it's really there to do any filtering since that's the filter's job. I took mine off, might get a little better airflow, haven't blown up yet.

Would removing it yield better fuel economy? I do a lot of city driving so every MPG counts..

I think leaving it on would give better economy. Less air, less fuel.

I'd be willing to bet someones else's money on it.

So it's more of a performance mod then? I'd love a little more get up since I don't have a turbo in my Cruze lol.

Yeah but probably not hardly noticeable. I'm no gearhead, and I can't honestly vouch for anything I've said lol. All I know is I took mine off and under the foam it looks like any other filter you'd put in any other car, so I figure it can't hurt.

Couple things to know:

- The foam is there for locations with a lot of dust, like Arizona

- You can remove it without any issues. (Would be no different if you installed a K&N which doesn't have the foam)

- If you don't replace the foam before it dry rots there is a chance it can mess with your MAF but this isn't usually a problem if you replace on schedule.

Did this answer your question?

Yeah you pretty much covered everything! I guess I'll leave it on because I live on the dustier side of Maui so my car sees a lot of dirt. Much to a point where if I let it go for more than a couple weeks between washes my car will get filthy. But I've been keeping an eye on the filter and it's still pretty clean after about 15,000 miles. I've heard that K&N's free flow filter lets more dirt in so I wouldn't really trust having that in my car..

Everyone has an opinion on K&N. I think it really comes down to each persons preference. Of course it will screw with your MAF if you over oil but I never had a problem with mine when I had my Silverado. There are plenty of good/bad stories for both sides.

Removing the foam filter (foam delete) gives you a louder intake when you go resonator bypass/delete. I'm not gonna touch the K&N, I'll wait for the others to post links to how they filter dust.
