Okay so recently I had a DC sports race header, AEM CAI, and a dezod 2.5" n/a exhaust system installed on my 2009 scion tc. The shop that installed everything said I need a downstream o2 sensor harness extension. Where can I find one??? please help thanks

 

search "anti-fouler".

 

i dont need the anti foulers. I need a 36" harness extension for the downstream sensor. The stock one was long enough.

 

i call b.s, i have every single pipe aftermarket and didn't add no extension.

 

A couple feet of 16 gauge wire and a soldering iron should do the trick Cheaper than anything else you can buy. Just be sure to throw a little heat wrap around it to keep it from melting.
