Has anyone here used aftermarket K&N air filters?

5. I installed one on my '91 Silverado back in '02.

When you change the oil just take it to the sink and wash it,then clean the sink with BBQ Grille Degreaser.
I bought it from my former boss who rotates trucks every ten years,he got it wholesale from a dealer as it was a one year lease return.
The lessee apparently screwed up the OD to avoid mileage charges.
I would guess 12,000 miles per year after the first 100,000 mile year would be 340,000 miles.
It burns no oil and still has good compression and still smokes the tires into third gear which leads me to believe that the K&N Filter is doing it's job.
It was my daily driver up until a year ago when i bought a slightly newer Sonoma for better mileage.

They will save you money,period.
However,there is another brand which is cheaper in case you think you might sell later.
