2004 + Yamaha YFZ450R AIS SAS PAIR Valve Block Off Kit YFZ450 YFZ 450 R SE

The PAIR / 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.

Kit includes 3 high-temp rubber block-offs,
plus a PAIR 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.
