    Designed as an emissions control modification, the Triumph air injection system pumps air into the engine to force more fuel to burn inside the cylinder. While that may sound commendable, it comes at a cost. The downside of the system is that it creates a lean fueling condition that spikes exhaust temperature -- that encourages your header pipes to turn blue and makes low-speed throttle adjustments finicky at best. This upgrade has all the components needed to replace the air injection system for a finished look and a cooler running engine. The British Customs Air Injection block-off bolts are machined from aluminum in a low profile design and coated black to match the head perfectly or left raw: either way they virtually disappear.


    • Reduction in Exhaust temperature
    • Discourage blue pipes
    • Reduces lean conditions
    • Low profile air injection plugs
    • Copper crush gaskets
    • Rubber nipples
    • Air box plug (for stock air box)
