The SAS / SMOG system feeds fresh air into the
exhaust to aid in the combustion of unburned fuel.
It was designed to improve emissions but will cause
problems with many aftermarket exhausts / mufflers.

Plates are machined from billet aluminium.
Stainless steel bolts & washers, plus a
high temperature airbox cap is supplied.

Also includes a SAS valve eliminator plug, to
fool the ECU into thinking it is still connected
& prevent it from throwing up an error code.

Fix exhaust popping & backfiring with aftermarket cans.
Achieve true A/F ratio for Autotune / mixture adjustment.
