For the price - a GREAT replacement
I wasn't looking for great power gains with this SR Performace 70mm upper intake - my old stock throttle body and plenum were just so gummed up with carbon and oil deposits I just thought it best to replace them. This piece is a GREAT compromise between the more expensive, name-brand TB's and plenums and your tired, dirty stock ones. I had a very small issue with a port that is located on the back of the SR plenum (facing the firewall) that seemed to accept a larger hose than my stock one I took off. The port (I can't remember what it went to) appeared to take a 3/8" diameter hose and my old plenum's port was a 1/4". Easy fix was to get an adapter that went from 1/4 to 3/8 and some extra hose and done. Install time for me was quite long because I took my time and was in the midst of other projects with this car but any semi-experienced home-mechanic can change this thing out within 1-2 hours. Like I said, not a big change in performance, HOWEVER, the car does seem to idle better and there is slightly better throttle response. My car has over 300K miles so it's not a good benchmark. As a suggestion to AM, would you consider adding the oval-shaped rubber gasket that sits in-between the upper and lower intake to the kit? I wanted to replace mine when doing the swap but couldn't find the gasket alone - it is only included with some larger gasket kits on some other sites. I ended up re-using my gasket with no problems. Very satisfied with this product!!
