I was using wix paper air filter in the Rev up airbox. Next I switched back to the stillen intake and kept the oem Z-tube. This combo felt the best to me. The stillen intake sounds along with Z-tube, both amplify to a deep mean roar which I love and it also kept the excellent throttle response and is Rev happy. This setup is a keeper for me.

If anyone wants a brand new revup airbox, pm me lol or check out classifieds later when I post it

Scrutinizing over what intake is better for the miniscule performance is an exercise in futility. For intakes, look out for an used cheap Z tube (sound) and an used Stillen intake. Or a revup air box. Whatever comes by for sale sooner (or cheaper). Same for the spacer. I was looking for either the Motordyne spacer or the Crawford plenum. Found the plenum first so I got that.
