HP Gain and CARB Exempt!
Small HP increase but was able to feel the difference. Illustrated installation instructions was a plus but there was a small variation in the removal of the air inlet duct and resonator. The illustrations on the duct & resonator were probably for pre-2007 TSX's. Won't need to do a Calif. smog for another 2 years or so since I just got the car and smog was required for the transfer of ownership. However, the CARB exempt sticker with reference number should resolve any issues.
Great bang for your buck
Great intake! If you notice other intakes ofer more horsepower but ft. Lbs. of torque is where it's at and that's why I select this intake. Torque is where you're going to get that "seat of the pants " feeling when you hammer the throttle and this intake absolutely delivers! This only problem I have with the installation is they don't supply a coolant hose. That want you to reuse the original one which is a stretch. Come on K&N it would only cost you a few cents to add one to the kit
