ZZP's stage blahblah TB's blow ass because they don't get the blade to sit right when they ship them out after porting them. Have Reptile port you one or hog it out yourself. Save yourself the possible headache and buy a DHP PCM too...skip ZZP's crap. And even more x1,000,000 on the open cone...your no where NEAR the mod level to need one...even an N/A car with heads and a cam I'd want the colest air possible...stick the filter in that little opening on the right side of the fender. Also...for the last damn time...NO SPACER.
