Fitted mine today.
My butt dyno do feel the responsiveness and the speed going quicker than before. I'm very happy for the money smile.gif
Took me about 3-4 hours, because i take my time and cleaning the inside of the plenum and the throttle pipe.
If someone decided doing it themselves, you need to get the Torque wrench and it's very important for the installation. Find the one that can do Inch Pound rather than Foot pound.
Just a quick note, that i already have the CF tube intake, Drop in K&N filter, and the Amuse Exhaust. So that's probably why i felt the improvement more.
