Don't know how many hp I gained but its very noticeable. My 2011 Corvette Grand Sport loves it. Replacement was easy and took about 20 minutes and just used a screwdriver. My vette runs easier and peppier under normal driving and when you press the accelerator it really responds. I did not realize how important air is. Too early to tell if the gas mileage improves but I am sure it won't until my foot gives it a rest.
