RacingLine Boost Hose Kit – Audi S3

RacingLine Boost Hose Kit for MQB 1.8 & 2.0TSI. The RacingLine Boost Hose package replaces the original rubber charge pipes with beautiful smooth-flowing silicone replacements, uniquely reinforced with internal wiring for guaranteed stiffness under the demands of high heat and boost levels.

The kit is a direct OEM replacement: simply remove the old weak, flexible rubber hoses and replace them with our five-piece kit. Simple.

Stepped internal joint transitions give a port-matched laminar airflow path, greatly reducing turbulence versus other non-stepped designs. Of course our kit is pressure tested far beyond the turbo?s capabilities, the system maintains performance under extreme temperature and high-boost conditions.

By minimising these restrictions, the smoother airflow and optimised hose routing ensures that the turbo meets less resistance and can thus perform more effectively – moving a larger volume of air and minimising turbulence.
