Enhance Your Performance with a Genuine Bosch 74mm Porsche 997 Turbo Throttle body
Upgrade airflow and unleash the potential of your Porsche.
The genuine Bosch 74mm throttle body is a proven performance upgrade for various Porsche models. Originally equipped on the iconic Porsche 997 Turbo, this precision-engineered component delivers significant improvements in horsepower and torque. It seamlessly integrates with 996 Turbo and 997.1 Turbo, creating a highly efficient air intake system for your Porsche.
Unmatched Quality and Reliability
Don’t compromise on performance. Unlike unreliable imitations, the Bosch 74mm throttle body is built to withstand the demanding conditions of high-performance driving. As the trusted OEM supplier for Porsche, including their most extreme track-focused models, Bosch delivers unparalleled quality and durability.
Are bigger throttle bodies worth it?
- That’ll depend on the rest of your build, including the manifold, air filter, air intake system, engine, ports and many other factors!
- A 74mm throttle body upgrade on a 996 turbo is quite nice. It’ll pick up in power and throttle response without any compromise.
How much HP can a throttle body add?
- With a nice Ypipe upgrade, plenum and air intake, the 74mm throttle body upgrade can boost your mostly 996 turbo 35 to 50hp
- If you’ve fully built your engine to 3.8, 3.9, 4.0, 4.1, 4.2 or even 4.3L you’ll be wanting to head over to the gt3 throttle body or full GT3 intake manifold section!
- However, on a stock 996 turbo, increasing the throttle body with no other changes will not fit well nor net much of a power increase.
- So be sure to complete the air intake system for the best result!
What size throttle body is a 997 Turbo?
- The OEM (Bosch) Throttle Body for Porsche 997 Turbo is 74mm
Are there any downsides to a bigger throttle body?
- An excessively oversized throttle body can cause twitchy throttle response making the car hard to handle at low speeds or even on the track in subtle corners. The 74mm throttle body works very well on a 996 turbo. The GT3 can be a little large, or a 92 or even 100mm would be an issue.
- Without proper tuning to match the throttle body the fuel trims and idle can be very lean.

Trevor Morris2024-04-22Todd is the ultimate godfather of Porcshe! His knowledge and informative videos have been invaluable to me as a Porsche enthusiast. I'm incredibly grateful for his expertise and guidance. I had an intermittent problem with my 996tt that has plagued the car for 6 years, no shops were able to figure out the problem. I emailed Todd and he narrowed it down within a couple emails, and sure enough he guided me to the problem and it was a simple fix in the end. Not to mention Todd's tuning skills are off the charts, as the car also traps 144mph in the 1/4 mile. Keep up the fantastic work, Todd!
Chris Roundtree2024-02-19I wanted to thank Todd at Protomotive Motorsports for going above and beyond when he helped me sort out a problem with a product that I had purchased from another vendor. Todd seems to always have the knowledge to put together the best combination of parts to make any model Porsche not only go fast or handle better, but do it reliably. He always answers the phone. In the rare event he doesn’t pick up he gets back to you within twenty four hours. Emails get responded to just as quick. I really appreciate having some like Todd available when working on any Porsche as you know he has a proven setup to satisfy any goal. Thx Chris
Antreas Smilas2024-01-22Super in every way..2 years now in ecu and tcu perfect power delivery ,reliable,and fast as mr Todd promise in number...i can say even i draggy was the same numbers as promise to achieve with this set up.
Taylor Berg-Kirkpatrick2024-01-04Todd has got to be the world's expert in forced induction Mezger Porsche engines. I've worked with a bunch of mechanics, tuners, engine builders across multiple Porsches over multiple decades... and Todd has been the most helpful and knowledgeable of the bunch. And this has even been true while working with him remotely! (I'm in CA and he's in AR.) Just by looking at my logs and hearing about my engine rebuild, he's been able to diagnose stuff that in-person mechanics have not been able to. For example, Todd was the only person looking at my car to suggest a problem with a BRV could explain some of the weird behavior... following his advice, I dug in myself... lo and behold, torn BRV diaphragm on bank 1! Wow! Further, Todd has the most experience tuning these cars of any tuner I've worked with. Tune is absolutely solid and safe. Very very confident in his work!!! Absolute strongest possible recommendation!!
N K2024-01-04Todd and his team are true professionals and they always provide excellent customer service, quality parts they sell and very reliable engine builds. This is very rare in our industry today. Great job Protomotive!
raphael wirth2023-05-29Todd est l homme de la situation…. Des difficultés ou des problèmes pour régler le problème? Todd trouve la solution malgré la distance ( je suis français) Merci à lui et son équipe pour leurs conseils … Maintenant mon 997 turbo fonctionne à merveille et est un véritable avion de chasse! Je recommande a 1000% !!! À bientôt pour d autres évolutions !!!
Adam McGregor2023-04-05I don’t think there is a better shop to shop entrust your Porsche to then Protomotive and the Knighton’s. Just search there name with 993 and you can start to get an idea of their storied history of building monster but reliable 911 Turbos! I have over 12 years and 30k miles (street, autox & track) on the Protomotive set up on my 997tt and it has never skipped a beat!
Piotr L. Pawlak2023-04-05Unfortunately they could not resolve my issue, but Todd tried very hard to find some other resolutions. He was very helpful and responsive.
B W2023-03-23Todd is by far the most professional and knowledgeable Porsche person I have ever worked with in my life and I have had many cars and have been doing this for over 20 years. He not only knows how to overcome every single problem, but also knows how to explain exactly what he is doing and brings the car to a point where it feels like stock even though it has double or triple the power. If you go anywhere else you would be making a mistake
Alex May2023-02-20The engineers at Protomotive are absolutely the best. They performed extensive work on my Porsche GT2 and I literally could not be happier. Their work, attention to detail, problem solving and communication with me were all next level. Customer service is remarkable. I had a question while at the track, on a Saturday, and Todd immediately responded to my questions. Class act.
