If you’re chasing more horsepower, faster spool, and a sharper throttle feel on your Porsche 718 Cayman or Boxster, the stock turbo inlet is one of the most overlooked restrictions in the system. It’s small, plastic, and worst of all — it chokes off the turbocharger right where airflow matters most.
That’s why RaggDoll developed a 3" High-Flow Turbo Inlet designed specifically for the 718 platform. It’s one of the highest ROI upgrades you can make on any 2.0L or 2.5L engine, tuned or stock.
The OEM turbo inlet on the 718 is narrow, restrictive, and made from thin plastic. It also includes a resonator chamber that dulls throttle response and kills induction sound.
Here’s how it holds you back:
RaggDoll’s inlet is a fully aluminum, direct-fit upgrade that removes the resonator and expands diameter throughout the flow path — resulting in 22% more airflow over stock.
Key features:
When tested on tuned 718 builds, the RaggDoll Inlet has shown:
And since it bolts on in under an hour, it’s one of the fastest ways to feel a real difference in your car.
Whether you're chasing times at the track or just want more excitement on daily drives, the RaggDoll Turbo Inlet brings power earlier, more consistently, and more efficiently. Combined with a RaggDoll Intercooler and Turbo, it creates a high-flow ecosystem that gets the most out of every PSI.
You can install this inlet without updating your ECU, but if you’re running a custom tune, the improved airflow gives your tuner more room to optimize ignition, boost, and fueling.
It’s the perfect supporting mod for:
