Im going to have RPM do it anyways, they know their stuff better then anyone, so im sure cutting the hole is no problem. Im just looking for performance, sound, and aesthetics.

Looks, fit, finish and if something goes wrong with the engine the dealer cannot point to the intake as the problem.... its usually always worth a little more to go with OEM if the option exists, especially if OEM is the superior product.

What he means is that the HP gains are minimal if there are any at all. However, your car will sound nicer, you will get a little better throttle response, and some have said the 3.8 will rev better in the upper band....

isnt the X51 considered OEM? isnt it a porsche aftermarket product?
