The Best Bolt on Performance Upgrades for Late Model Porsches

IPD logo

What a well made product! I could tell instantly upon unboxing that my IPD Plenum was a well made piece of equipment...

We replaced the stock plastic plenum with this well made piece of aluminum and to our surprise we could tell the difference right out of first gear. It no question added a little boost to our get up and go and with an easy installation to begin we couldn’t be any happier with this addition to our little Porsche! Nice job IPD!!

Great customer support when I had concerns about used product purchased and decided to purchase a new Y-pipe. Y-pipe and plenum was also used in my prior 997.1 Turbo with tune. Highly recommend.

I installed the IPD Plenum in my 2004 Boxster S 3.2 and it works very well. I was a bit skeptical due to Mexico City altitude, but it worked very well. I can feel the performance gains between 2,200m and 3,100m (7,218 ft and 10,171 ft) above sea level.

I’ve heard a lot of chatter about IPD plenums over a few Porsche forums. Some people say they have a moderate improvement some say no improvement at all. I called IPD expressing my hesitation. Upon my discussion with Greg, I was confident that if I ran into any issues, I would be fully refunded. So, I purchased IPD plenum and 74mm throttle body. In the first couple of hours of driving, I didn’t see much difference, but THEN, after the ECU adjusted itself I felt SO much improvement! It picks up much faster across the entire bandwidth. Later on, I had ECU remapped to accommodate the additional airflow. Finally, with IPD plenum, 74mm throttle and remapped ECU, it almost feels as I have 911 in the body of 986, such a massive difference! Any 986 owner would agree that it feels underpowered from the factory, even S modeld. Well, not anymore!!!! Special thanks to Greg for his excellent support, now I have this setup on my sons 986.1 and my 986.2 — HUGE DIFFERENCE!!!!! Regards, Vadim!

The past years my 997.1 has been running like clockwork, more eager and better response from the Tiptronic box. A perfect investment! ?

997.1 Carrera

The IPD Plenum in combination with the GT4 throttle body, headers, high flow cats, exhaust and a tune produced phenomenal results in increased horsepower and torque. Based on Dyno results the Cayman now produces 317 hp to the rear wheels. The throttle response and performance are mostly contributed to the IPD Plenum and GT4 throttle body. I couldn’t be happier! Greg and his team are incredible to work with. Great job IPD!

I love the performance improvement. I plan to purchase another plenum for my 2000 911
