Breathe Easy—Your 718 Just Got Set Free
The RaggDoll Motorsports High-Flow Air Filter & Cold Air Intake System is a complete intake upgrade for the Porsche 718 Cayman and Boxster (2.0L and 2.5L turbo engines). Designed to eliminate factory intake restrictions, this system improves airflow, reduces heat soak, and delivers real, measurable performance gains—without sacrificing OEM fitment or drivability.
Unlike simple drop-in filters or open-element intakes, this system replaces the entire airflow path, from the factory cold-air duct to the turbo inlet, allowing your engine to breathe the way Porsche originally intended.
Porsche engineered a large cold-air duct into the 718 chassis, but the factory airbox only accesses a narrow, baffled inlet opening that restricts airflow under load. At higher RPM and boost levels, this creates:
The RaggDoll intake system removes this bottleneck by fully utilizing the OEM cold-air duct and feeding the turbo with cooler, denser, unrestricted air.
This intake system was developed through on-road testing, track use, and dyno validation across multiple Porsche 718 builds—from stock vehicles to high-power turbo upgrades.
Proven results include:
Unlike open intakes that pull hot air, the RaggDoll system maintains a true cold-air feed while delivering race-level airflow.
Fully compatible with stock or RaggDoll high-flow turbo inlets.
Installs directly in place of the factory airbox with basic hand tools. No cutting, no permanent modification, and no tuning required.
RaggDoll Motorsports designs components specifically for the Porsche 718 platform. Every intake system is engineered with airflow analysis, thermal management, and real-world testing in mind.
This is not a generic intake or cosmetic upgrade.
It’s a platform-specific cold air intake solution built for performance.
Built differently — because performance demands it.
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!
