Have gained noticeable power due to the IPD Plenum and Y-Pipe, would recommend to anybody looking for more than what stock has to offer.

Stock, this twin turbocharged car's ONLY "weak" point has been its lack of the various sounds that would come along with an NA performance car otherwise. Luckily there are plenty of aftermarket exhaust options to bring out a better exhaust sound, but I was thrilled to find how the IPD Y-Pipe and Plenum helped to increase the glorious induction-type noises heard in-cabin, after installing the Y-pipe to tap into for Meth nozzles (which would not be the best idea to do with the OEM y-pipe, as it is thin plastic.) These parts are really solid and offer a lot of confidence with regards to being tapped into for the injections ports. I am also sure that these components added to the quicker spool that my car has, after further tuning by Sam Ahdoot of By Design, once installed, due to their increased intake airflow. Lastly, they look the part that this platform offers much more so than the plastic components that come stock.

We have chosen to use IPD plenums on all of our Porsches. We honestly believe they increase the airflow into the engine, improving performance. We noticed the increase as it related to low end grunt improvement. We highly recommend doing your research before the purchase and installation of any aftermarket components. In our particular case, we have found Mr. Greg Martin to be an invaluable resource with regard to IPD products.

Plenum and Y-Pipe great product!

I observed a significant increase in both HP and Torque immediately following the fitting of the IPD Plenum and IPD Y Pipe, they were both relatively easy to fit and required no special tools or expertise. I could not recommend both these products highly enough; I am very happy indeed and several of my friends have fitted these same parts to similar cars and all are very happy with the results as well.

Great product, reaction time improved nicely.
