ETS 15+ WRX MAF Extension Harness

Product works as advertised, only issue was shipping time

Does the job!

Works better than Cobb extension harness and fixed idle issues I was experiencing. After troubleshooting for boost/vacuum leaks, faulty sensors, and clogged catalytic converters, this piece solved the ‘phantom’ issue. Car would have a rising and falling idle between 600rpm-1200rpm, then stalled out. Mechanics replaced MAF but the problem persisted. No CEL was present. After replacing this MAF harness all idle issues went away. Thank you

No check engine light/works as it should 👍

Installed 1000 miles ago with no issues. Super fast shipping and love the free stickers too 😎
