📊 Back-to-Back Dyno Tested – Real Results

During dyno testing, even after seven consecutive full-power dyno runs, the HPD intercooler maintained a cold-side temp of just 40°C, compared to 65–70°C with the factory unit.

🔥 That’s a 25–30°C drop in intake temps, even under sustained load – meaning more power, lower EGTs, and reduced heat soak.

💪 Nearly Twice the Size of OEM

• Core Size: 600mm x 300mm x 76mm

• Almost double the volume of the factory intercooler

• Bar & Plate Core for unbeatable heat dissipation and toughness

• Proven resistance to heat soak – perfect for towing, 4WDing, and heavy use

🛠 Built to Perform – Built to Last

• 2.5” Mandrel-Bent Piping – up from the OEM 2” for improved flow & throttle response

• Cast Alloy End Tanks – durable & high-flow

• CNC Machined MAP Sensor Boss – welded on for perfect sensor fitment

• 10mm Thick CNC "Knuckle Duster" Mounting Brackets – rock-solid install
