hey for all of you that have taken off the old air filter asembly and put a stand alone air filter/clear on. What type did you get? I want to do this too but too lazy to measure so I figured someone who has done it could tell me what kind of unit they got and I could just get the same kind. Thanks

For what model truck?

Never mind I called the guy at K&N and they helped out, I got headers now and 8mm plugs, Iridium NGK Plugs, Accel Coil!!
