Please Note: Only available for purchase and shipment within the United States 

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 Audi S4 and A6 2.7T 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.

Harnesses are assembled in-house at 034Motorsport and tested before shipping.

*Please Note: This harness is designed for use with the factory Hitachi 2.7T MAF sensor, and proper ECU calibration for the Hitachi sensor.  Hitachi MAF sensor part number 06C133471A is not included*
