AMS Performance R35 GT-R Upper Intercooler Piping

Stepping up from the 60mm factory pipes to full 76mm (3″) tubing, the AMS Performance R35 GT-R Upper Intercooler Piping gives your boosted charge roughly 60% more cross-sectional area between the intercooler and the throttle bodies. Built-in MAF provisions make it ready for a speed density conversion or blow-through MAF setup, and each pipe is flanged for TiAL blow off valves and finished in durable wrinkle black powder coat.

• 76mm (3″) piping replaces the 60mm factory upper pipes

• Roughly 60% more cross-sectional area than OEM

• Ready for speed density or blow-through MAF setups

• Flanged for TiAL blow off valves

• Durable wrinkle black powder coat finish

More Flow Between the Intercooler and Throttle Bodies

The factory R35 upper intercooler pipes were sized for factory power levels. As boost and turbo size climb, those small pipes become a choke point, and pressure is lost before the charge ever reaches the throttle bodies. Our 3″ upper intercooler pipes open that path up, so less boost is lost on its way to the engine and your turbos don’t have to work as hard to deliver the pressure your calibration is asking for.

Flexible MAF Options

The upper pipes include MAF provisions, so they work with whatever metering strategy your build calls for. Keep your MAF sensors in the intake and seal the pipe ports with AMS R35 GT-R MAF Block Off Plates (sold separately), and no ECU calibration is required. Building bigger? The same piping is ready for a speed density conversion, the go-to route for high-horsepower R35s today, or for relocating the MAF sensors to a blow-through position. Either of those routes requires a custom ECU calibration. Run speed density with the factory MAF sensors mounted in the upper pipes and they keep supplying the ECU’s intake air temperature signal, so no rewire kit is needed.

Built for TiAL Blow Off Valves

Each pipe is flanged specifically for TiAL blow off valves, one of the most proven valve designs in motorsports. Factory and other aftermarket valves will not bolt to these pipes, so plan your build around TiAL valves when ordering.

Engineered to Match Your Build

The SnailWorks Engineering Team developed this piping in configurations for both stock and AMS intercoolers, intake manifolds, and throttle bodies, so every connection lines up the way it should. Most aftermarket piping is designed to fit. AMS engineers it to dominate, with the fitment, flow, and finish to match the rest of a serious GT-R build.

Product Notes

• Select your installed intercooler, intake manifold, and throttle bodies when ordering.
• Flanged for TiAL blow off valves only.
• No ECU calibration is required when the pipe MAF ports are sealed with AMS R35 GT-R MAF Block Off Plates (sold separately) and the MAF sensors remain in the intake.
• Speed density conversions and blow-through MAF setups require a custom ECU calibration. Failure to calibrate can cause engine damage.
• Installing with non-AMS aftermarket intercoolers may require additional parts and custom fabrication.
