Unlock your turbo’s true potential
The RaggDoll Motorsports Turbo Inlet Elbow is a high-flow intake upgrade for the Porsche 718 Cayman and Boxster platforms, designed to eliminate the severe airflow restrictions of the factory turbo inlet. Built for tuned street cars, upgraded turbo setups, and track-driven builds, it delivers improved airflow, faster turbo response, and increased power headroom without sacrificing OEM fitment or drivability.
The RaggDoll Motorsports Turbo compressor Inlet is engineered to dramatically increase the efficiency and responsiveness of your factory BorgWarner B03G and K04 turbochargers — and is fully compatible with all 718 982 hybrid turbo upgrades as well.
By eliminating the restrictive, factory pre-compressor bottleneck, our inlet allows the turbo to breathe freely, improving both power and drivability across the entire RPM range.
Installing the RaggDoll Inlet is a highly rewarding upgrade — typically a moderate DIY and a straightforward install for most shops.
Independent Dyno testing shows 5–7% gains from stock to lightly moded and tuned setups, with up to 30+ horsepower gains possible on aggressively tuned and full bolt on cars.
But the performance story doesn’t end there. Thanks to the massive increase in airflow, power comes on faster, builds sooner, and holds stronger — and your Porsche 718 982 Cayman or Boxster will sound incredible, with a sharper, more aggressive induction roar under throttle.
Ideal for tuned and untuned 718s, upgraded turbo builds, ethanol setups, and track-focused cars looking for improved airflow, quicker response, and reduced turbo strain.
This upgrade has been installed with great success by many DIY owners. If you’re not confident with hands-on mechanical work, we recommend having a professional shop handle the installation.
Optional/required extras: high-flow intake system, upgraded turbocharger, ECU calibration
The RaggDoll Turbo Inlet Elbow is engineered to work as part of a balanced airflow system. For best results, pairing with a high-flow intake, upgraded intercooling, and properly matched turbocharger is strongly recommended.

Liza & most of the time Vince is amazing...lol. Nah, kidding, these guys are awesome folks to deal with. I purchased their Stage 2 turbo, turbo inlet, intercooler, engine tune, and high pressure fuel pump for my 2018 2.5L Boxster GTS and they're products and service have been top notch throughout the entire process.
Raggdoll Motorsports set up two dyno sessions for my Porsche Turbo S. The Porsche touts a 4.0-liter built engine and head work facilitated by Sam at ByDesign. Also has the XR ByDesign turbo kit with all the supporting mods. The first session the PDK kept transitioning out of manual mode. During the second session a boost leak at the throttle body boot ended the session early. We managed 812 hp on a Mustang dyno at only 20 psi of boost.
The people behind RaggDoll Motorsports have been in the game for a very long time and really know their stuff. They have a passion for modifying cars and are enthusiasts before anything else.
I purchased a RENNEN turbocharger for my 718 T. I had a special request, which was to get the turbine housing coated with Swain Tech white lightning thermal barrier coating and RaggDoll accommodated without hesitation even though it was something new for their team.
Hey All! Shout out to Liza and @Raggdolls718. Amazing customer service, product knowledge and a top quality product. Liza went out her way to accommodate my tight timeframe and the level communication and level of detail shared was amazing.
I purchased the Raggdoll Series One turbocharger upgrade and the turbo inlet upgrade from RMS for my Porsche 718 Cayman GTS and was very pleased with both the products and the customer service from RMS!
