Read the topic here and tell me if I'm wrong to think the filter is doing a crappy job. I know it will not grab every last bit of dust and that you trade better filtration for more airflow but I still think that is a lot of buildup for only 6-7K miles on the filter (Car had close to 15K at time of pic). also, the poster that goes by the name ?ROCK? works for the shop that made the SRI. I'm just starting to wonder if every one is taking his word as God since he works for the only shop that is making parts for this car.

As said in the thread - there's always a bit of dust that weill make it past any filter - especially unoiled ones. I only use well oiled and maintained K&N's in my cars - never had an issue, and I highly doubt that small amount of dust will do any real damamge anyway.

Basically, don't sweat it.

I have done a lot of offroading in dusty conditions and while after a day of being out there I'd have to replace the OEM filter, it never let anything past it. Personally, I would remove your 'CAI' and put the OEM back on. Unless you really want all out performance, then remove the entire filter. More air is good, right? ;)

Test have shown OE paper elements filter damn near the best out there, but that comes with a price, and cuts flow which equals hp/tq.

The onyl filter coming close to filtering as well as paper elements are the new synthetic ones.

I wouldn't ever run an oiled filter as I don't want to see the consequences of having one on the engine all its life. Also on newer vehciles too much oil put on while cleaning them is effecting MAF sensors, the oil gets over them and screws them up. But then if you don't put enough on you aren't filtering for shit.

I've dealt with oily messes for about 15yrs now on my bikes, i wouldn't want it in my car

I have a OEM filter, ~70k miles and I have never seen anything like that in the intake of my car. Mine is clean.

I don't see the point of CAI. Maybe 2hp more for essentially vastly reduced filtering quality.

I wouldn't be concerned with it. I looked inside my intake duct and I remember it looking similar. I use one of the K&N filters and it seems to work very well. I sent my used motor oil to Blackstone Labs for analysis and everything is looking good. Here is the report. I would suggest it if you are concerned. I think it cost around $20.

Someone did a study comparing air filters on some specilized piece of equipment made for testing air filters. It made me consider trying to see if I can find an AC Delco filter to replace the K&N in my Dodge.

I've been using a K&N. Not for performance, but just something to replace the stock air filter and maybe, maybe better gas mileage. Sure, there are arguments over what it can and can't do, but to be honest unless you're running around with the same exact car I am, I really wouldn't trust the comment.

At some point, every car runs a little bit differently. The 2001 Accord V6I have now really didn't seem to benefit from it as much as my last car, 2000 Corolla, slowest POS V4. I don't regret my purchase though.

Same here. I replaced my K&N with a AC Delco.

I will never run another K&N myself. I use paper filters and I just change them more often.

Well, put me down as a K&N user. Put in my first K&N in 1994 and have been using them ever since. I have had them in my T-bird, Countour SVT, daughters zx2, wifes Saturn and my current Subaru and Corvette. Any real benefit......prolly not, but no problems either. For the 5 minutes it takes to clean them once a year I don't consider it a big setback. Spraying on the proper amout of oil after washing the filter is the only critical step.

Well, I hate to tell you but there's a lot more dirt getting by your K&N filter than there is getting by anybody's unoiled, stock filter.

K&N filters are very nonrestrictive, but they make up for that by filtering almost NOTHING.
OEM filters are very restrictive, but filter very well, K&N is very nonrestrictive, but doesn't filter for crap.

If you live in an area with lots of dust, or you're extending your oil change interval, or you have a very close-tolerance performance engine, or you want to keep your car for a very long time, I'd just stick to OEM, or at least change to a larger paper filter.

I will have to find the page where a magazine took common air filters, wrapped them in varying amounts of saran wrap and the like and didn't affect the power of most cars. Unless your driving a real sports car the chances of your air filter inhibiting your power are pretty damn slim.

For sport cars and those relying on "ram induction" type techniques (basically they use the cars/bikes speed to help push air through) then ya, sometimes a different air filter might help but in most cases only if you change the airbox and connection to the engine as well.

IOW - when I looked at hoping up the G35 I had it required replacing the airbox and intakes.. everything else would have been tossing money to the wind

yeesh, look at the dirt on the throttle body/plate. thats horrible. i would suggest replacing that thing and getting your OEM filter asap. it is correct that most OEM parts are the best on the market, but they aren't designed with performance intentions, they're designed to do the job good for a price. you can tell that the guy lives in a dusty area though, since the picture of the throttlebody/plate has dust all around it on the engine itself though.(Colorado)

edit: this is, if you have this air filter.

Exactly. A stock air filter can flow more air than your stock engine can possible ingest.
