Default IPD Plenum

Have any of you installed the IPD plenum on your 992’s? If so, is it a modification you found to be worth it to do? I know dynos seem to suggest a legitimate increase in the overall horsepower/torque figures, but is it something that’s felt from the driver’s seat?

I've heard the opposite about plenum mods...except from those that manufacture or have them In essence, without other complimentary mods and tunes, the juice isn't worth the squeeze.

I'll see if I can dig up the data/review(s) where I heard this.

Not the 992, but you'll get the gist of it from reading.

I agree. I thought I read somewhere M-Engineering stated previously it didn’t help with power increase and part of the power band there was actually a decrease.

That's the source I was trying to remember, the forum post was just what I could find that was supportive of it.

I've reach out to a vender... (won't say the name out of respect) I was told I won't get power increase.. same thing with headers..
I was recommended to spend the money on the DO88 Hoses instead...

1) DO88 Turbo inlets hoses
2) D088 Intercooler pipe kit.

just based on flat6motorsports testing, I imagine you get some bump, but nothing you will feel. I installed the full big pack intercooler setup for the sport design bumper from do88, the turbo inlet pipes from do88, as well as their plenum.

the carbon fiber vents top and bottom are nice, seems like most people are using their hose kit, I figured might as well use their entire kit.

Beautiful setup. Have you dyno’d the car since the update?
