These square 4 pin O2 extensions will extend your Traiblazer's Front O2 wires by 12 inches providing neaded length for installing headers. When ordering more than one, change quantity to two. Most header installs on the Trailblazer require two of these O2 extensions.

If buying for a header install, please confirm the manufacturer does not already include all needed O2 extensions before purchasing these. Any returns will be issued as store credit mius shipping only (no cash refunds).
