Product Information

The Porsche 718 982 Cayman and Boxster whether a Base, T, GTS or an S are all equipped with the same rear quarter-panel-mounted heat exchangers, presents unique challenges in maintaining optimal intake air temperatures, especially under increased performance demands. The factory cooling system, with its limited coolant volume and modest pump capacity, can struggle to dissipate heat effectively. Introducing a dual-pass intercooler in this setup can exacerbate these issues by increasing coolant temperatures and system resistance, potentially leading to heat soak.

Why Intercooler Efficiency Actually Matters—Stock or Tuned?

Whether you’re running a factory tune or pushing serious boost, intercooler efficiency is mission critical. Intake air temperature (IAT) directly affects ignition timing. And on the 718 platform, the ECU doesn’t mess around.

Timing pull starts around 104°F (40°C) IAT. Go beyond 120°F? You’re losing timing fast. At 140°F and higher? Say goodbye to a big chunk of your power—even if your AFRs and boost look perfect.

Tuned cars suffer even more because they’re pushing hotter, denser air—and unless you keep IATs low, you’re leaving horsepower on the table every time you go wide open. That means slower lap times, weaker 60–130 pulls, and inconsistent dyno numbers.

An inefficient intercooler in a tuned 718 can cost you 20–40 horsepower or more, just from heat soak and timing reduction. So whether you’re daily driving, canyon carving, or track smashing, you need a system that holds up under pressure—and heat.

Because when your cooling system is designed right, you don’t need gimmicks.

You just need results.

And that’s exactly what our single-pass delivers.

Why Choose the RaggDoll Single-Pass Intercooler?

Our single-pass intercooler is engineered to maximize cooling efficiency without overburdening the existing system:

  • Enhanced Coolant Flow: The single-pass design ensures lower resistance, allowing for optimal coolant circulation even with the stock pump.

  • Reduced Coolant Temperatures: By preventing excessive heat accumulation, the system maintains more stable intake air temperatures.

  • Increased Core Volume: A larger core provides greater surface area for heat exchange, improving overall cooling performance.

 

Synergy Effect If Used With The RaggDoll Extreme Charge Cooling Kit

For those seeking the pinnacle of cooling performance, our Extreme Charge Cooling Kit complements the single-pass intercooler perfectly. Featuring increased coolant volume, an upgraded pump, and a triple heat exchanger setup, this kit enhances the system’s capacity to manage heat, ensuring consistent performance even under the most demanding conditions.

Raggdoll Single Pass Intercooler Vs Dual Pass and Proven Performance

Let’s be real—the only reason anyone built a dual-pass charge cooler for the 718 / 982 was to keep the coolant inlet & outlet on the same side, just like the factory setup. It wasn’t about performance—it was about convenience. But in doing so, they overloaded a system already struggling with limited heat exchanger capacity and over whelming the system.

And here’s the kicker: even when tuned for optimized flow, dual-pass intercoolers in real-world testing (like Mishimoto’s study on the BMW F80 M3/M4) showed negligible advantages over a well-designed single-pass system. That’s right—negligible, even with ideal coolant flow tuning.

Meanwhile, our RaggDoll single-pass intercooler? It brings that same performance out of the box. No gimmicks. No unnecessary routing. Just a clean, efficient, plug-and-play system engineered to keep your Porsche 718 Cayman or Boxster cooler, faster, and running stronger—without complicating your build.

Because when your cooling system is designed right, you don’t need marketing tricks. You need results.

And that’s exactly what our single-pass delivers.

Key Features

  • Optimized and Tailored to the unique cooling architecture of the 718 Cayman Boxster.

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.

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.
