I love the performance improvement. I plan to purchase another plenum for my 2000 911
Made a huge increase in boost
Nice upgrade to low end torque, throttle response, and sound.
I installed the Boxster plenum and throttle body myself, it was a very easy install, such a great design and performance for both my Boxster and 911 turbo. IPD has done a great job to make this a easy install especially the intake hose on the Boxster, it flexes quite well but is still strong.
I just wanted to upgrade for a little more horsepower but got more than expected!
I am so pleased with my purchased. I called IPD and spoke with Greg. We discussed what my intentions are for the car, and he recommended the standard Plenum that utilizes my factory throttle body as being better suited for what I wanted to get road performance wise (vs track), along with advising on a load of other considerations I was planning for the car. Since the installation, I can definitely tell the difference and am very pleased with the performance. :-)
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.
