The difference of opinion centers around the fact that K&N filters pass significantly more dirt particles than your average paper filter. The theory centers around whether the additional debris materially reduces engine life. I suppose the answer depends on how dusty your environment is and how many miles you expect out of your engine. There's also the cost of the cleaning kit, and the time and trouble to clean and dry the filter to consider.K&N AIR FILTER 33-2498 (4 cyl)
Seems like it's price-fixed at $52 w/shipping no matter where you shop. Do the math!
Some difference of opinion on these, but probably more theoretical than practical.
Reusable; good for 50,000 miles before first cleaning.
I use this in my car.
40k is a lot on a filter...Doing the math, five Wix filters shipped to my house from Fleet Filter is less than $80, which is less than a K&N filter and cleaning kit. If I change my filter every 40k miles, they'll cover me until the car has nearly a quarter million miles. That plus superior filtration and convenience makes replaceable filters the better deal.
