our logo
• Allows you to eliminate fresh air injection into your
exhaust system
• Each kit comes complete with a cap for airbox
• Made in the USA
Fresh air injected into the exhaust system on modified sport bikes
can cause backfires in the head pipes and muffler due to unburnt
fuel from modified fuel mapping combined with additional oxygen
spontaneously combusting in a high heat environment.

Driven's block off plates will stop the annoying and possibly
damaging backfires from occurring while allowing you to remove a
few pounds in associated valves and hoses from your bike.

On late model EFI bikes with 02 sensors, ESPECIALLY when using
Fueling controlers like the Rapidbike, the air injection system MUST
be blocked as it will introduce additional oxygen into the system
which will skew your 02 sensor's values and make it impossible to
get a correct tune.  Made in the USA.
