RacingLine - Turbo Boost Hose kit / MQBE / 2.0 TSI EA888.4 - TT / TTS Mk3 21+

The RacingLine Boost Hose package for the latest Gen.4 2.0 TSI engines 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. An essential upgrade for any 2.0 TSI EA888.4 car.

The RacingLine 2.0 TSI EA888.4 Boost Hose package is a three-piece kit to replace the factory soft flexible rubber hoses and replace them with our beautiful reinforced silicone replacement versions. The kit is a direct OEM replacement: simply remove the factory hoses, and replace them with the three uprated silicone pipes. Simple. Stepped internal joint transitions give a port-matched laminar airflow path, greatly reducing turbulence versus other non-stepped designs. Of course the RacingLine hoses are pressure tested far beyond the turbo’s capabilities, allowing the system to maintain 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. Within the kit, the two Intercooler Boost Hoses have unique steel wire helix buried within the silicone construction. This eliminates the very real risk of hose collapse, yet still allowing sufficient flexibility without wall distortion. A particularly good upgrade for any remapped 2.0 TSI EA888 gen.4 car running higher boost than standard.
