15. Apply a small amount of anti-seize to the threads of the oxygen sensor and install and
tighten it. Connect the wire and route the wire away from the exhaust piping, but allow
enough slack to allow for exhaust system movement.
16. Install the spark plugs and connect the wires to the proper plug. If the spark plugs have
a lot of miles on them, now would be a good time to replace them. When you install the
spark plugs, apply a small amount of anti-seize to the threads.
17. Install the appropriate connector pipe on the appropriate side of the vehicle and attach
them to the headers using the gaskets and hardware provided.
18. If you removed the inner fender panels and front tires; replace the panels and tires and
be sure to torque the lug nuts.
19. Connect the throttle body to air cleaner hose.
20. Connect the battery cable.
21. Check over the installation to make sure that all wires, lines, hoses, etc are connected
and have adequate clearance to protect them from the heat generated by the exhaust
system.
START THE ENGINE
Start the engine and allow it to warm up to operating temperature. Check for any unusual noises or exhaust leaks.
If every thing is OK, stop the engine and tighten all bolts while the engine is still warm.
NOTE: Check the bolts periodically to make sure they have not loosened. Re-tighten after the first 500 miles and
then again at 1000 miles.
IMPORTANT CHECK LIST
Be sure that all brake lines and fuel lines are clear of headers and/or connector pipes.
All spark plug wires, battery cables, or other electrical components should be clear of headers
and/or connector pipes.
If dipstick tube was removed, make sure it is installed properly and that the dipstick has been
replaced.
Double-check the tightness of all bolts including brackets and accessories.
