What model number is that KN Filter? Did you have to replace the center rod to screw the top on? It looks tall.
It's a K&N 3300, not 3320 as I stated earlier. Sorry. Yes, I added a longer bolt to accommodate the taller filter. Started out with the 3320 but the motor's RPM ran a little higher during idle. After installing the 3300, the RPM drop down to what it should be.
