If you've installed an aftermarket intake, or done an engine swap in your Subaru, then you may have a situation where your MAF sensor harness now seem slightly too short. When pulled to tight, prolonged stress on the wires could cause damage to the harness, leading to some annoying hiccups.
We make a custom plug and play MAF sensor extension harness, which allows you to connect your MAF sensor with a little extra slack, so that you don't have unnecessary stress on the wires. It could also allow you more room to make things look neater by running the harness in a more discrete way.
Our standard extension length is typically about five (5) inches, but if you would prefer a different length for your application, let us know!
