Great extension!, 1.19.2010 Reviewer: KENNY YAU (BROOKLYN, NY) No problems whatsoever. Helped me out a lot since I have a race header! Good length for most applications, 11.19.2009 Reviewer: J (Houston, TX) I used this for the installation of an ITR on my base RSX. The secondary sensor with the 10" extension just barely reaches with no slack in the line. Should be ok, but I'm always worried the wire might get damaged after one good bump. Would be nice if it were a 12" extension instead of 10". Other than that, quality and fitment are great! Harness Extension used on Secondary o2 Sensor on Kidd Racing Header Install, 8.26.2009 Reviewer: Tim Fritz (Lancaster, PA) I used one of these harness extensions when installing my Kidd Racing "Krusher" on my '03 Type S. The extension did all that it was made to do and fit perfectly, no hassles. It wasn't absolutely necessary to run this on my secondary o2 sensor, as I could have just unclipped the female end of the harness from the retainer on the base of the firewall but I dislike doing things half assed so I opted for this extension and it worked great. By one now. A must for race header install, 12.9.2008 Reviewer: Brian (South Setauket, NY) I bought one O2 extension when I was installing my DCRH. The fitment was perfect and gave me no problems. In retrospect though, I wish I had bought the second one at the discounted price because the O2 sensor without the extension was barely long enough to work. I would've felt more comfortable using extensions on both O2 sensors. I say by 2 if you are in doubt. It'll save you time and grief. 02 extension, 9.20.2008 Reviewer: lmo (Mansfiedl, tx) plugs up perfect. works exactly the way its suppose to. i did not know u get a discount on your second one i bought them seperate and did not get a discount =[ View all 8 reviews
