Plenum
I have a 2000 Boxster, headers, exhaust, de snorkeled, vivid racing ECU flash. I just purchased a 74mm upgraded throttle body (#98660511501) can anyone direct me to a plenum I can use? I don’t want to buy a $800 IPD plenum, I was wondering if I can buy a used one off a 911 or something that could work with the upgraded throttle body....thank you in advance.

Hi Ray,
You can use a 997 plenum. It is also know as a distribution T or distribution tube/pipe. Search ebay. You can find them for under $50. Here is a link: https://www.ebay.com/itm/2006-Porsch...53.m1438.l2649
Good luck!

Pedro’s Garage is a website that has a a lot of good information for the Boxster. He has an upgraded plenum on there. He also has upgraded fuel injectors and a few other goodies. I haven’t tried them myself but they sound good. Pedro is pretty involved with the PCA forums.

I'm amazed at how you fit everything in. I bought all the parts silicone pipes/997 plenum/Tb etc. I've tried to fit everything in but a little too tight. It sits/rubs on the metal edge and didn't feel comfortable leaving it like that. All the parts are sitting on a shelf now.

You probably need to cut back the elbow to give you more space. Over on the 986Forum you can check out the Radium King’s solution which I like a lot! Look for my posts in the technical section of that forum. I will be mentioning this in my upcoming video, Boxster Intake mod, epilogue.

Hi
I'm activating this thread as I'm planning to upgrade my 03 986 S.
Plenum + TB upgrade is on top of my list so I've got few questions:
1- would upgrading to a bigger Plenum & TB be restricted / affected if I kept the stock air box?
2- Any experience or data to show the IPD plenum is better than the plastic 996 or 997 plenums of the same diameter?
3- is there a pre-made tubing (similar to IPD tubing) to ease the installation?
I'd appreciate your thoughts & input in this matter..

We love people who search before starting a new thread !

1- would upgrading to a bigger Plenum & TB be restricted / affected if I kept the stock air box? No but you will get a lot more airflow by installing the 987 airbox
2- Any experience or data to show the IPD plenum is better than the plastic 996 or 997 plenums of the same diameter? Yes Flat 6 Innovations recommends them
3- is there a pre-made tubing (similar to IPD tubing) to ease the installation? I believe IPD has a hose.
