This finest quality reinforced silicone MAF hose for the B5-S4 C5-A6 or allroad with the 2.7T. Designed to go from the stock B5-S4 C5-A6 or allroad 2.7T MAF housing to the 2.7T Y-Pipe. Directly modeled off the OEM hose to ensure optimal fitment.

Replaces OEM Part Number: 078 129 627 T or 078129627T

NOTE: This is modeled off the Bosch MAF Sensor cars. The only difference between the Bosch MAF hoses and the Hitachi MAF hoses is that the Hitachi MAF hose has a fitting on the bottom to receive a small breather. This breather is capped off for 90% of the Stage 3 conversions that run hoses with no hole in the bottom, so it has been proven to be ok to delete this breather for almost 10 years now. So if your car is equipped with a factory Hitachi MAF and has this breather hose, it must be capped off to use this hose.

Features a larger inside diameter and smoother surface for better flow, and stiffer construction to prevent collapsing. Manufactured from high-quality automotive silicone for life long reliability.

Available in black only.
