British Customs Air Box Removal Kit for Triumph America / Speedmaster

The better your Triumph breathes, the better it performs. Its just that simple. With the British Customs Air Box Elimination Kit you can remove the restrictive OEM air box and snorkel configuration and open up the fuel system with some freebreathing K&N cone filters. Dollar for dollar, this is the best performance upgrade you can get for your Triumph America or Speedmaster.

Simply scrapping your stock air box doesn’t work – it also serves as the mounting point for some pretty important equipment like your relays, fuses, solenoid and rear master cylinder. British Customs reengineered an entirely new air intake system, complete with a new battery box design that provides all those essential mounting points.

The battery box is made of lightweight aluminum with wrinkle powder coat finish for durability. All brackets, hardware and fastening points for reinstallation of stock components are included, right where you need them. 


  • Breather hose filter
  • Two K&N cone filters
  • Mock air box with all mounting points for stock equipment
  • Exposed version exposes the K&N cone filters
