K&N I hadn't planned on using one on my ti but wanted to try it out. It's still on the car after a few thousand miles. It increases the induction noise up front (not totally unpleasant to me but it is louder) but the upside has been an increase in the mileage, about 1.5 to 2 mpg better than stock. HP gain? Probably minimal. It's a good kit, fits well and went on without any mods. I ran the supply hose up from the bottom and kept it short of the filter (to keep water at bay). I'll keep it on... |
