may have been my thread you were reading. I cut the bottom of the box out than flipped it over. This has a fully exposed factory filter angled away from the engine. you keep thr factory clamping system to hold the air filter in place. It does nothing for power but sounds awesome.
also mines a 2wd sport so it does not really go off road.
Why you ask? Im a cheap skate do it your self kinda guy.
