Works with Factory 74mm Throttle Body

The incredible 991 Porsche Turbo received a completely redesigned exterior but the engine remained virtually identical to the previous model 997.2 Turbo. This 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.

The 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 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.

The 991 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or a series of spirited driving sessions, which of course IPD recommends only be performed on a closed course circuit. Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.

This version of the 991 Turbo /S plenum utilizes the factory 74mm throttle body and delivers impressive performance gains throughout both horsepower and torque curves for both stock and modified Turbos.

Features:

  • Manufactured using only the highest quality materials
  • Gives your vehicle a truly unique and exotic style
  • Outperforms the competition with dyno proven results
  • A taste of luxury combined with unbeatable power gives you a superior edge
  • Fitment guaranteed and withstands the test of time.

    Top Class Watch
    Color: sliver band blue face-G5885G
    I really love this watch, its very bright in the night, it was very easy to set the time on it, I also love the weight of this watch, it's definitely of top class quality, thankfully I didn't need the tool to adjust the band because it fit perfectly fine, plus the quartz system is working quite well, hasn't missed a second since I set it. Time keeping is amazing. Overall, I love this watch so much, I'm thinking of buying the black face one as I bought the blue face one.

    Tracking Process & Quality of Product
    Color: Black Watches for Men/Black Dial-2870
    I don't know where to review the tracking process so I will do it here. I just love the fact that they list stop by stop where your order is. I ordered this for my son for his graduation present and was very excited to give it to him. I was able to see how many stops the driver had before he got to me which allowed me to not only have a better idea of its arrival time, but I was also able to enjoy a buildup of excitement as it got closer and closer. As for the quality of the product ~ both my son and I are very impressed and more than satisfied with the watch so far. I was very trepidatious as so many items, especially jewelry items, look stunning, gorgeous, beautiful, high quality in the pictures online and are nothing short of utterly disappointing when you get them. This watch renewed my belief that there are honest sellers out there. I will say that we just got the watch today so this is purely about the initial presentation and look of the watch. So, the packaging was super nice, high-end quality. Each piece (bands, watchface) were separately wrapped in nice, thick plastic to protect from scratching. The boxes (box for watch & slip cover outer box) were great quality (you know, so many companie's packaging falls apart at barely a touch, which makes me wonder about the quality of what's inside). Thorough, grammatically correct (mostly) directions included; also had tools for taking out links along with fairly easy to follow pictured & written directions. We did have to use a separate pin with a head (like tailors use to mark hem points) to push out the pins bcz the one included bent. One thing I really appreciate is that the company said they are there anytime and to please let them know of any issues. Usually companies do all they can to make it as hard as possible to be contacted. I couldn't stop looking at the watch! It DEFINITELY looks SO MUCH MORE expensive than it was! And the workings move like a Rolex (smoothly), not jumpy like the workings of normal watches. Even my husband remarked on how "Rolexey" it looked. I ordered the all black watch. Again, we've only just gotten it, but if the initial presentation is any indicator of its performance, WE'VE GOT A WINNER!!

    Good looking cost effective
    Color: Gold Silver Stainless Steel/Blue Dial-2870, Color: Gold Silver Stainless Steel/Blue Dial-2870
    Good for the price. Looks nice from a distance. Feels heavy. Is a bit noisy when you walk. But value for money.

    Low cost watch returned.
    Color: Gold Silver Stainless Steel/Black Dial-2870
    I returned this watch the next day after receiving it. It was very attractive and I hope it would work as advertised. The watch came in shrink wrapped plastic that was very tough to removed. I feared damaging the watch. I set it then tried some of its features. The stopwatch worked but it did not reset to the zero position properly. The 24 hour time indicator was off by one hour. The rotating bezel had black lacquer on it that was tender to the touch. A fingernail could have damaged it and a very small nick had already started out of the box. If everything had worked properly I would have kept it for the money spent. I guess you get what you pay for so I am now shopping for a higher quality watch.
