No filter... far out thats harsh man.
The filter was actually worth around the $70 mark, but I got it cheaper. It's not the best one on the market, but $70 aint that cheap for a filter.
It has only been letting dust through for a few days because I checked it a little while ago and it was fin. Im guessing some water from the recent rain we had damaged the filter somehow, so I doubt any damage was done.
As for the sound of the intake, yes it is addictive man. I absolutely love it, you gottta try it Acid.
When you thump it past people, downgear into high rpm or race another car I assure you that the sound of the intake will turn heads.
I love it when I am racing a commo. Initially the commo usually gets in front until the 3.9 gets wound up.. and when it does, the intake roars and the EA shoots past the commo.. hehehe.. must get them confused.
Ok, thats enough blabbing from me for now
