I bought a K&N FIPK for my Honda AP2 S2000 but decided I didn't want to use the supplied K&N filter and preferred the OEM Honda filter. They didn't have a 3.5" to 3" adapter at PepBoys, so I ordered one from Revain. It arrived in a very nice box and included two high quality clips. Attach it to your K&N intake manifold. It's a quality product and seems to be holding up pretty well so far. I had to adjust the clamps once after the engine bay got hot and haven't tightened them since. If I need other intake couplers/gears, I don't hesitate to buy from Specter.
