Plug-In MAF Conversion Harness, 2.7T, Bosch To Hitachi

No reviews


034Motorsport is pleased to introduce the first and only Plug-In 2.7T Bosch to Hitachi MAF Conversion Harness!

This plug-in harness will convert early (1997 -2000.5) Audi S4, RS4, A6, and Allroad models equipped with Bosch MAF sensor to the later (2001+) Hitachi MAF sensor without any cutting, splicing, or wiring skills needed!
Since the Bosch MAF's male connector is not manufactured separately from the sensor, 034Motorsport engineers designed our proprietary male connector in order to make this plug-in harness a reality. The connector is printed in-house on 034Motorsport's Dimension Elite 3D printer out of P430 ABSplus Plastic to ensure perfect fit and durability.
Designed for use with the Stock 2.7T Hitachi MAF, Part Number: 06C 133 471A
Harnesses are assembled in-house at 034Motorsport and tested before shipping.
