The perfect compliments to Fabspeed's exhaust upgrades, this high performance intake plenum and y-pipe from Innovative Pro Design provides substantial power gains by increasing the efficiency and flow of the engine's air intake system.

The incredible 991 Porsche Turbo received a completely redesigned exterior but the engine remained virtually identical to the previous model 997.2 Turbo. This latest Turbo is the most powerful, revolutionary and capable Porsche Turbo to ever come out of Stuttgart. This latest generation Turbo engine, titled the 9A1, delivers 520 HP (560 HP with the "S") and once again, raises the proverbial performance bar in the sports car world.

IPD Plenum

The new 991 IPD Turbo Plenum is nearly identical to the previous 997.2 Turbo Plenums. The new IPD Turbo Plenum is offered in one single 74mm version which utilizes the factory 74mm throttle body. The 991 Turbo intake manifolds are smaller than the 997.1 Turbo manifolds which is great for improved boost response and gas mileage but less than ideal for making substantial power gains. The 74mm TB provides more than adequate flow for these more restrictive intake runners eliminating the need for a larger 82mm "Competition" version.

The already explosive power of the 991 Turbo can be further increased with the new 991 Turbo IPD Intake Plenum. The patented IPD Plenum design works exceptionally well with all forced induction applications and the 991 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay well above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed, most critical and most enjoyed.

The 991 Turbo plenums deliver smooth and linear power with considerably quicker boost response creating a longer and more desirable power band. The Turbo plenums deliver reliable performance for both street and motorsport applications enhancing the already visceral Porsche Turbo driving experience.

Features:
  • Superior and more efficient design over the factory intake
  • Deliver impressive power gains regardless of modifications
  • Produce substantial gains for both turbo and NA applications
  • Do not require an ECU flash and will not cause a CEL
  • Aluminum Plenums run cooler and don’t suffer from heat soak
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty
  • NOTE: If you are upgrading your throttle body along with the IPD Plenum, you may need to visit a dealership to have them perform a manual throttle body adaptation process. Some customers have reported that installing the throttle body and plenum while the battery is disconnected results in the car performing an adaptation check once the battery is reconnected, alleviating the need to visit a dealership. However, Fabspeed recommends having the adaptation performed at a certified dealership for optimal results.

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.
