This is a custom maf adapter harness that allows you to run a 2g DSM maf in a 1g DSM. The 2g maf flows much more air and is far better at making horsepower. I have built hundreds of these harnesses over the years and have never had any problems. Email me with any questions you may have.

Note: With the 2g maf, the car will need to be tuned.
