Is the K&N filter just a bunch of hype or does it really make a difference?
The annual K&N air filter debate...

I bought a 3" x 14" (whatever a standard base diameter is) back in 1980 and still have it. It's been used on a half dozen or so cars through the years. They said 1 million miles. Well I've put an honest 200,000 or so miles on this one and it still works.
Sorry Guys, I can't see, well, let me restate, I can see the sunlight through the filter when held up to the sun.
How can these holes filter the air?

Check your intake after the filter. Standard air filters don't leave a fine grit in the intake, K&N does. That grit goes through the motor... Your trading a minor if any increase in HP for a very real reduced engine life due to increased wear from that grit.
Use at your own risk.

Agree. Look at the piston rings. if smooth, good seal. If scratched, poor seal due to dirty air.
I saw this on a car I bought, so I replaced the K&N with a stock filter.
The Doug Roe quadrajet book lists some filter restrictions. With a proper stock filter you can get good filtration and good airflow.

Been using them for years...never had any issues with dirt that I know of but never had a reason to pull the heads...HP/performance difference is noticeable to me...like said before wash and re-oil when the color starts to fade... The main reason is I hate having to fork out $35.00 every 30-35k for a paper fliter, for an extra $20 I get one that lasts forever... A little greener too...no throwaway...just my .02
Waste of money and should come with a Tokyo Drift DVD when you buy them.
I never understood the "filter charger kits" that require you to soak them in oil. Why does a filter need oil if it has no moving parts? So the dirt can stick to it or else it will easily get into the motor because the element is so porous. Just not appealing to me, I'll keep my paper fire retardant filter any day, still looks pearly white.

Well ?? no pics ???Just bought a Spectre filter for the Camaro ( arch rival to K&N )
We'll see how it works.
Actually I bought it cuz it looks cool
Except you have to buy a recharge kit, which brings the cost up and close to just buying new paper filters.

X2 :yes:
Bought a recharge kit many years ago, had to finally use it after all these years since I used the oil that came with the filter up finally.
Small performance gain, small. Barely noticeable, but it is still a gain.

When did paper filters cost $35.....I dunno..........instead of dirt in the intake......use the noggin.........take oil samples.........if the dirt is real, it will show up instantly in the oil.....no waiting around.
Remember Vacu-pan.........friend ran dirt late models with a vacuum pump to pull crankcase down........pulled that S_it off, as soon as the dirt show'd up in the oil samples.....on his 25K motor.
