This extension harness allows you to run the stock wiring for our 15+ WRX Intake. No splicing or cutting. Plug and play connection.
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
Installed 1000 miles ago with no issues. Super fast shipping and love the free stickers too 😎
