A. Place the supplied air injection adapter into the

driver’s side exhaust air injection manifold port

with the taper facing up (if the exhaust manifold

is machined with an inverted flare seat for the

air injection flare fitting, ignore this point). See

Air Injection Modification diagram. If the

threads in the manifold are unusually deep

(such as in some aftermarket exhausts), use

the supplied washers to “space” up the adapter.

B. Thread the supplied tube nut and 5/8” flared

tube into the factory exhaust manifold injection

port.
