replace air filter ??
 

Hi, i have a ZJ 93, 4.0L with 784 injectors, is it a ide to replace the standard airfilter with something else?

Everybody has their opinions, but here's mine. The original pad can flow 6 times the air required for the engine. It also is a cold air intake system, taking high pressure air from in front of the radiator. I can't see where any improvements can be made to it.
