Using OEM air filter with KN intake
Hey all,
I was wondering if using an oem air filter with a KN air intake is a good or bad idea. My oem engine rebuild will be completed next week and I want the engine to last as long as possible. I've heard KN filters don't keep your engine as clean.

Maybe OEM filter with OEM air filter box is the best way to go? Longevity, wise.

I think you are smart to be concerned about the filtering capability of the k&n filter. I think using stock filter with the k&n would work fine, assuming it fits the pipe, which I don't know if it does.
But a question. What is your goal here? If your car already has a k&n, then yeah, see if a stock filter will fit, done. If your car is stock, and you are just after the sound, then modifying stock airbox is an option. Search on this forum for diy.
If you want the sound AND the underhood look of exposed filter, then getting something like k&n and using stock filter sounds like a good plan.

but if you dont want it to look funny under the hood with a kn pipe and a stock filter, why not just get an aem dryflow, awesome fitlering media with good flow..
make sure you still have the K&N rubber vstack that goes in the end of the pipe and purchase this filter

Step 1. Remove airbox lid. Drive. Say WOW out loud. A lot. Drive around like that for a while, and realize maybe thats a little TOO loud. Realize something between that and stock would be perfect. Not to mention this is a recipe for heatsoak.
Step 2. Cut out most of stock airbox internal dividing wall. But leave a good inch or so, to help prevent hydrolock should any water ever make it into airbox.
Step 3. Use a piece of the wall to make a plig to cover the airbox resonator hole. Glue in place with silicone caulk or similar.
Step 4. Remove air guide tubes from underside of lid.
Step 5. Drill a 3" hole in passenger side of airbox. Purchase 3" flex duct hose and bulkhead connector. Duct fresh air from adjacent fender opening into airbox.
Step 6. If this isn't loud enough, add another duct and hole, maybe on the bottom of box, piped in from below radiator.
