K&N Drop-In Filters

Cmike2780 · 06-25-2010, 02:55 PM

Anyone here try the K&N drop-in air filters? Any gains or just worthless?

I heard sometimes they over oil and it screws with the MAF sensor, any truth to that?

Install for anyone who is interested:
Difficulty 1-10: 1 very easy

New K&N Filter x 2

There are (2) clips holding each filter tray to each airbox. Just unhook, slide towards the front of the car & pull up.

Side by side comparison of stock Nissan filter & K&N. The K&N rubber gasket around the filter is slightly thicker than stock but will fit the tray & airbox. Don't worry about which direction the louvers face, it only fits if they are vertical.

Make sure the airbox is clean. I found a lot of old leaves in there. Taking that out alone will get some hp back.

Installation is the reverse. The K&N will be snug, but it does fit. You will have to muscle the clips back on.

Might as well clean the engine bay.
