Removes stock air box to improve airflow and increase performance.

The better your Triumph Modern Classic breathes, the better it performs. Its just that simple. With the British Customs Air Box Elimination Kit you can remove the restrictions inherent with the OEM air box and snorkel configuration and open up the fuel system with some free-breathing K&N cone filters. Dollar for dollar, this is the best performance upgrade you can get for your Bonneville or Thruxton. 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 de-sign 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. This upgrade works with stock side covers. Available as full kit with Air Filters and hardware or Battery Box only (including hardware)

Kit Includes:

  • battery box
  • K&N crankcase breather filter
  • K&N high flow air filters
  • Stainless steel hardware
