RacingLine Cotton Air Filter for VW Golf 6 Passat Scirocco Skoda Octavia II 1Z. Requires 2.0 TDI adapter.

Welcome to the RacingLine 2.0 TDI Cold Air Intake System with pleated cotton filter for A5-platform vehicles, including the Golf mk6 GTD and TDI, Scirocco TDI, Octavia II TDI, and other models featuring this engine. This racing-derived system incorporates RacingLine’s high-flow, maintenance-free cotton filter. In testing, RacingLine intake systems reliably deliver the highest power gains on the market, and with this cotton filter, it becomes an easy-to-install and maintain solution.

Developed and tested based on RacingLine’s extensive motorsport experience, gained with their exclusive 2.0 TDI race engines, this system combines OEM design and quality standards with significant power increases for modified vehicles. All handcrafted in the UK. The construction of RacingLine’s pleated cotton filter requires no maintenance, offering a truly practical filtration system for those who prefer to avoid cleaning and oiling a Trifoam filter.

Airflow is not by chance. Developed with F1-level CFD programs, it’s no surprise that so many high-powered cars choose the RacingLine intake. The large airbox volume and maximized filter surface are key to this, providing airflow that supports higher power without restriction.

By allowing cold, dense air from outside the engine bay to reach the fuel metering unit more efficiently, the system delivers a truly impressive increase in airflow – up to 9% higher at peak power compared to the original intake system.

By reducing turbo spool-up time by up to 500 rpm in some cases thanks to the system's increased efficiency, ultra-fast turbo response is guaranteed.

You’ll hear the rich induction sound of this racing intake as soon as you step on the gas, enhancing the TDI’s acoustics. However, being a fully enclosed intake, noise levels are well controlled.
