it is time for me to change my filter. is there an air filter that is reusable like the k&n but does not require oil? I heard that paper filters are better than the oil'd up ones because the oiled filters sometimes leave a residue on the MAF sensor. Or is there nothing to worry about the k&n panel filter?.

If you oil a filter properly and then let it sit on a shop towel overnight you should have no MAF problems. I've been using that style of filter for years w/ no issues. I like the green filter better than the K&N myself.

 

thanks for the tip.

 

Lil' Ryan, think about a Blitz panel filter. I'm gonna get one when my my stocker craps out

 

I think the oil-on-MAF issue is overhyped. I used the Perrin Foam filter for 20,000 miles (washing and oiling with every oil change) before I pulled my MAF sensor and looked at it; there was a little bit of dust buildup but no visible oil or sludge on the sensor. I agree with Peaty's suggestion of letting the filter sit and the oil settle; another tip is to make certain the filter is 100% dry before you spray the oil on.

 

I personally have run K&N panel filters on every car I've owned and never a prob.

I just wash, let it sit in the sun(make sure its compeltely dry), reoil it and let it sit for a solid hour... then for good measure, If drop the filter onto a towel 2 or 3 times on each side to drop any beaded oil or any excess oil trapped between the actual filter fibers and the metal mesh... just shake things up a bit, get any loose oil off... and its ready to go...

Now if you are a bit paranoid about it... then take the extra step to make sure you have no doubt or worry in your mind, I personally liked the suggestion of leaving it on a shop towel over night... personally, I drive a lot, and am rarely sitting my car... so if thats your case, then id keep the stock filter for days like this... just pop it in for any trips you may need to make... and then the next day replace it with your oiled one

Hope this helped

I prefer OEM paper filters over any oiled element. I've used K&N filters in the past on other cars and I like the idea of a reuseable element but in actual use I found the cleaning and re-oiling process to be a chore. I think the K&N works fine if properly cleaned and oiled.

I also like the OEM filter because I believe it is less restrictive than the K&N. On Vishnu's old site pages, there was a reference to back to back dyno runs comparing the OEM and K&N reuseable, and the K&N lost 2 to 3 horsepower at higher RPM. The OEM has many, many more pleats which greatly increases filtering surface area for less restriction. At the time, Vishnu Performance decided not to offer K&N filters for sale along with their other upgrades.

Maybe some dyno-equipped shop would like to do another back-to-back test under controlled conditions to see if this still holds true. I know that every dyno has a margin of error and very small differences in power should be considered a run-to-run variance.

me too. i've been using the Green Filter for about 3 years now. no problems.

 

I didn't switch to an oiled filter because of increased airflow; no one can detect the minimal HP increase (2-3 hp, max) such a filter would give you without tuning as part of your filter install. The reason I switched was because the OEM filters, although they are cheap and do flow well, kept coming out CLEAN! After 3k miles the filters looked nearly new, which is a problem -- I wanted them to be BLACK with gunk they cleaned out of my intake charge.

When I switched to the Perrin oiled foam panel filter, I definitely picked up more gunk and finer particles. Here in Arizona our air is full of extremely fine dust and talcum-power-size sand, as well as tons of brake dust (we never get rain to wash this stuff out of the air or off the road). The Perrin filter shows visible discoloring after just 2k miles and by 3k miles it is nearly black in the center and overall quite dirty; I also see tiny bits of stuff like bird down, pollen, flower petals and other kinds of junk collect on it. Anything to keep this stuff out of your engine is good!

 

I agree with meilers... truth is... The Dyno testing that Vishnu did was on new filter vs new filter... K&N operates BETTER when its dirty in comparison to the stock filter... Clean VS Clean, the difference is miniscule... So on your way to 3,000 miles, you will have better airflow with a K&N or in meilers case a Perrin... because these filters are set out to COLLECT more gunk and keep our engines healthier, and allow our intake systems to breath happier even when dirty, as opposed to the congestion they will experience when the stock element is dirty...

i switched to the green filter because I goto school in riverside (with Winding Road). We have the 1st most polluted county tied with LA. we get their smog, and our mountains trap it. plus there is a lot of dust too. plus i'm REALLY glad i had it when we had all those fires and that ash was floating around for days. also, I did it so i'd never have to buy a new one. cleaning and re-oiling is more convinient.

 

I've had an oil analysis done twice now and it shows that the Green Filter is working just as well as paper. My Si levels are in one case below the average and in the other about average.

 

i like paper because the other styles dont get cleaned enough


if you need an air filter hit me up i have the short ram because of the FMIC so i have a bunch of airfilters that are new
