RaggDoll Motorsports Turbo Inlet Elbow

Porsche 718 Cayman & Boxster 2.0T / 2.5T S & GTS

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.

Why This Turbo Inlet Exists

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.

Key Features & Benefits

• Larger Internal Diameter — Reduces inlet restriction and pressure drop
• Optimized Bend Geometry — Smooth airflow path into the compressor
• Improved Turbo Response — Faster spool and sharper throttle response
• Increased Power Headroom — Supports higher boost and larger turbochargers
• OEM-Style Fitment — Direct bolt-on with factory sensors and connections retained

Who This Is For

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.

Install & Tuning Notes

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.
