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

QUESTIONS & ANSWERS

Ask a Question
  • Hi, will this work for a 19 sti. If not, is there one available that does? Thanks

    This is for a WRX. Not an STI.

  • I purchased an ETS cold air intake for my 2017 WRX and it’s connection is weak and my car is struggling to hold an idle and throwing a MAF code. Is there a warranty on the extension harness I can use?

    We offer a warranty on all of our products to the original purchaser. Give me a call and we can go over the warranty process.
