Four harnesses with different front and rear lengths
The kit includes two 16-inch front four-pin extensions and two 18-inch rear four-pin extensions. Match the harness positions and connectors to your installation, with the wiring routed clear of the exhaust.
Check the parts already supplied
O2 extensions are included in Kooks header kits where needed. This is the replacement kit, so check your existing header-kit contents before ordering another set.
