Real-world cooling results

Independent rolling road testing on a Stage 1 remapped 1.8T showed dramatic reductions in charge temps and a healthy mid-range power improvement:

• OEM cooler: Inlet 128°C, outlet 49°C, heat-soak evident
• AIRTEC cooler: Inlet 126°C, outlet 23°C with a 12 bhp mid-range gain

Figures recorded on a 1.8T platform using the same AIRTEC core. Expect the same strong results on your Mk4 1.8T. Higher tunes typically benefit even more.

What it replaces and why it works

This kit removes the restrictive side-mount style setup and pancake pipework, replacing it with a high-flow, front-mounted single pass design that keeps intake temperatures stable pull after pull. The result is repeatable power, improved throttle response and greater reliability for remapped cars and spirited driving.
