Designed as a high performance replacement for the longitudinal 1.8T with K04 or F21 turbo upgrade, and 2.75" ID TT225/VR6 MAF housing. Constructed from high quality, automotive grade silicone using 4-layers of reinforced nylon with wire reinforcement - this hose will not collapse even under extreme vacuum.
The intake hose is 3" at the MAF and 2.0" at the turbo inlet, and features provisions for all factory DV, PCV, vacuum lines. Perfect fit with the TT225 MAF housing inside the factory airbox, or any aftermarket air intake.
Please Note: Although it is larger diameter than stock, this hose can also be clamped down over the stock MAF and stock K03 turbo inlet using spacers.
