K&N AIR FILTER vs. STOCK PAPER FILTER

[GaryFenza]

I have a 2003 Pontiac Grand Prix GT 3800 Series II v6. I currently have a K&N air filter in the car, i hear speculation about these filters, that they are a waste of money and dont really dont do nothing. Anyone actually think that they make a difference in acceleration more than a nice new clean AC paper filter?? What is your opinion on these filters?

uh oh...here we go again

see this thread...haha

yeah Gary, I'd stick with a stock one unless your heavily modified.

Up at school, we dynoed a buick centry 3300 (If I remember right) both ways with the stock paper filter, then with a K&N drop in filter. The K&N didnt make any difference.

Well from what i hear, tomarrow im gonna go to the store and buy a Stock AC delco paper air filter, and get that K and N out of there.

I don't have any data to back this up, but I dropped in the K&N at the same time I deleted the U-bend and Resonator. Subtle but noticeable improvement in throttle response (faster revs), but having never dyno'd or tracked I don't have any idea if it is quicker.

Best benefit of the K&N is that the service shop never tries to sell my wife a $30 paper filter when she get's the LOF.

Some car enthusiasts have gone to great lengths through the years to run their own comparison tests of AC Delco paper versus K&N drop-in and other brands. Technically it is annecdotal info and could be taken with a grain of salt but regardless should be looked at in the K&N versus others debate. Here is a surprising one done on a Cadillac STS with a Race Technology AP-22 accelerometer.

Why Rich? Afraid of the K&N rep weighing-in defending his products.

Sheesh, that guy was a trip. I can't blame him for what he did, but puh-leeease!

You guys are too funny, I love it.

ok guys.....i took the K and N out today.......dropped a brand new Puralotor paper filter in, tight fit in the air box no leak arounds. To my suprise...the car shifted better and ran better, and THAT is no "immagination", next im changing my Trans Fluid and putting pennzoil high mileage ATF in

I've had a K&N for about a year now. I've seen no gains in MPG or performance "feel". That webpage with the dyno specs in really interesting Bob. Confirms what I have always thought.
