That setup is called "on the cheap & I needed a airfilter". It is still on there & works fine for now.
My gas mileage has increase ALOT with that POS filter there. Better then new stock? I dunno, but it is better than clogged, dirty, old stock. What I did IS NOT a performance mod. It was a nessessary mod to keep the car running.
