Rich Sound And A Couple Of More Ponies
I'd say it took me under an hour to install. I didn't have any issues. Not even with the provided silicone hose kinking when making the 90 degree angle necessary in order to connect from vent port on intake tube to valve cover. If you manipilate the tube the right way it can be achieved. The sound is rich and the horsepower improvement is evident when you climb to higher rpms before the next gear shift (manual) Imroved fuel economy? not sure and don't really care. Didn't buy it to improve on MPG
got this for my 08 scion xD. had to pull off the bumper to get in on, but it really wasnt that much work to get it going. went with the polished because i heard the MAF sensor wouldnt fit right in the powder-coated one. everything went in quick. throttle response is nice, and you notice the gains at the higher rpm range. not so much at the lower range. engine breathes much better too.
