Ducati Monster 1200 | 821 Jetprime PAIR Circuit Eliminator Cover Set

**Ducati Monster 1200 | 821 Jetprime PAIR Circuit Eliminator Cover** **Set**

The Jetprime PAIR Circuit Eliminator Cover set includes two CNC machined
aluminum plate that replaces the original cover on the engine head and a
aluminum cap to close the hole in air filter box.

The secondary air injection system (PAIR) routes fresh air from the airbox to
the exhaust system in order to aid the combustion of unburned fuel in the
exhaust.

This system is designed to improve emissions on stock exhaust systems, but
will cause exhaust popping and backfiring when you fit aftermarket exhausts.

The kit gives easy removal of the secondary air injection covers on the
following Ducati**** models:
