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