It was designed to improve emissions but will cause
problems with many aftermarket exhausts / mufflers.

Kit includes 2 x M12 cylinder head bungs
and a blanking cap for the airbox, 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.
Improves throttle response &  smothes out power delivery.
