The throttle body opening on a non-X51 engine is smaller so the hoover belt goes around that so that the intake hose from the new X51 air box fits.


Neil, What is the sound difference between the stock 997S air box compared to the X-51 air box?

Thanks for the explanation.

 

nice setup just wondering if the aero decklid was ever made to accomodate the x51 package from the factory.

 

nice!

 

This intake is really nice, and saves weight.

Only if you order the areo kit and the X-51 on a 997 from the factory.

 

SURE SWEEEET HAHA

 

The gruppe m is def a looker, but I doubt it is as good as the x51. The gruppe m for the e46 M3 made zero power.

 

2,540 USD after shipping!

 

I do not think there is any difference in the sound, which I am surprised at because the hemholtz resonator was taken off.

 

Thanks, I was thinking that too because I did a little experiment and taped off the hemholtz rez and noticed no real difference in sound.

 

The modification of the deck lid is part of the X-51 installation. The factory instructions provide a template for cutting. It is available on the RennTech.org site.

 

Good work... dremel the new hole and your good to go.
