I want to add a K&N Air Filter only on my 2001. I don't wanna do the whole intake right now. Are there any benefits to replacing just the stock air filter with a K&N?

I have a K&N in mine and love it. Seems to flow better.

Expect to get "they're junk" commentary. This question always does, so ignore it or heed the anonymous "experts" warnings. Interesting to note that every after market air intake system uses an oil gauze type filter. Take that for what it's worth.

Will you get any horsepower? I don't know. It does improve the air intake sound, which is what most owners equate to horsepower, anyway. The manufacturer will probably say it will increase horsepower. If so, your buttometer probably won't be calibrated to sense it.

I use either K&N or S&B oil gauze filters on our three vehicles. In fact, every vehicle we've owned has used an oil gauze filter. The AZ dust gets everywhere and I'd rather clean the filter with every oil change than buy a new paper filter. Just because you use one doesn't mean you can ignore common sense about when to clean them.

The biggest advantage to an oil gauze filter is that it's infinitely reusable. Keep it clean and save yourself a lot of money over the life of your car. Allow it to get dirty and it'll cause your car harm just as a paper filter will. There is a certain procedure for cleaning. Follow it...

The caveat is over oiling after cleaning. This is what gets owners into trouble. More is not better. It will possibly contaminate the MAF wires and cause poor performance. And the people who don't follow the procedure and experience poor performance are probably the same who don't like them.

One more thing...the K&N might not fit in the stock box. You may have to use a "zip tie" mod to get it closed

K&N fits perfectly. No need for any mods!

I use a K&N, but never oil it. Use an air hose to blow the dirt off. Yah I know should not do that either.

Breaths great, runs great, no dirt. no worries.

They have been proven to NOT filter as well as paper. And any horsepower claims are not backed up by testing.

Over-oiling WILL mess up your MAF sensor.

I'll stick with paper.

Oldvetter

Without oiling these filters, they will perform MUCH worse than paper filters. They depend on the oil to trap dust/dirt.

I suggest you look at your throttle body throat and then make that "no dirt" statement !

WAIT! Is today April 1st?????

Clean as clean can be.

I have two filters, and change them back and forth every few weekends at the track.

I have no "dog in this hunt" so this is only my suggestion--don't use a K&N filter without properly oiling it! Without oiling it properly, this filter does not filter the air very well. If you feel otherwise ( and I assume you must) I recommend you give K&N a quick call. I believe you'll find their response echos my suggestion. Whatever you decide, best of luck, Ron

What you always leave out of these posts is that this is on a track only car that gets rebuilt regularly.

Advising someone to run these filters without oil and to clean them with compressed air is just plain irresponsible in my opinion.

A new oem paper filter will flow more than a K&N, however with age and dirt the K&N will begin to outflow the paper unit. The oiled gauze filters main advantage is being able to be cleaned and reused. It should be lightly oiled after its cleaning and drying process.

tudland

Not to steal the post but if you over oil the filter how do you clean the mess up?

Dave68

Use CRC MAF cleaner:

No benefits at all. Only cons:

More air=more dirt

Pretty simple, why change out your great filter for an inferior one. If you want more air, just take the filter out completely.

AU N EGL

I never advised, I just said that is what I do.

When I touch the paper, it still has some oil on it somewhat. Not dry paper. I dont oil them.

now, that said, how many guys over oil their filters ?

can I guess that just about everyone?

if I could find paper cone filters that fit my air box, I would get them, use them and toss them regularly

Have not looked in over a year, so there might be something out there.

IMO, take it or leave it, do not over oil your 'K&N' or any oil paper type filter. Which may be cause for some tb oil residue, not oil blow by.

Mark C5

No paper in a K&N filter. They are made of cotton gauze. Maybe if you understood that you would understand why you need to oil them and should never clean them with compressed air.

I never have nor have any of my friends that run them. Maybe twenty people I personally know of.

This is America, you're free to guess whatever you wish .......... even when you're wrong.
