Why this kit

• Serious cooling capacity with a stepped core measuring 520 x 200 x 150 mm and 13,000 cm³ volume for outstanding heat rejection
• About 50 percent more frontal area and roughly 70 percent greater core volume compared with the factory unit for noticeable intake temp reduction
• Bar and plate construction with cast aluminium end tanks, flow-optimised for minimal pressure loss and rapid turbo response
• High-density internal turbulators to maximise heat transfer and keep charge temps stable pull after pull
• Protective anti-corrosion coating for long-term durability and consistent thermal performance
• Substantial improvement in exhaust flow from the SS304 stainless down pipe for reduced back pressure, less thermal load on the turbocharger and stronger mid-range shove
• Precise 1 to 1 fitment that mates to factory locations and hardware
• Plug and play install using stock hoses with no cutting and no bumper removal required

Real-world results you can feel

Lower intake air temperatures, quicker spool, and a freer-revving feel under load. Our team runs this setup on customer cars and our own builds, and feedback has been consistently positive for drivability and repeatable performance on the road.
