Looking for a cost effective way to increase the performance of your Triumph Bonneville or Thruxton? British Customs has designed an aluminum battery box that allows riders to remove the factory air box while maintaining all necessary securing points for relays, fuse box and starter solenoid. By removing the air box and installing the two supplied K&N filters directly to the end of the throttle bodies (EFI models) or carburetors (carb models), the motorcycle's intake system is opened up, allowing it to increase flow into the motor.

The aluminum battery box fit the battery, ECU, ECU spacer, starter solenoid, fuse box and replays while allowing the stock side covers to be fitted, allowing the rider to maintain a factory appearance. The British Customs Battery Box is constructed from aluminum and all including mounting hardware is machined from stainless steel. (Carb models only: Carb brace is constructed CNC from aluminum and anodized black.) The best known and best manufactured K&N air filters feature K&N's million mile warranty. Jet Kit includes 135, 140, and 42 pilots. All the necessary brackets, hardware, and fastening points for reinstallation of stock components are included.

Kit includes:

British Customs Battery Box Carburetor support brace (needed for carbureted models only) Custom stainless steel, washable crankcase breather hose filter in chrome finish K&N high flow air filters Rejetting kit (stock carbs) Hardware included

Can I use this kit for the 2017 Street Twin?
Unfortunately this kit will not work on the Street Twin but please be sure to keep checking as we are frequently releasing new products for the liquid-cooled twins.

After installing this and a set of 2+2 arrow exhaust, will the jets included in the kit be sufficient or recommend a different size?
The supplied jets would be for our high-flow exhausts like the Predator and etc therefore we cannot recommend a specific size for other exhausts as we do not know the qualities yet it should get you close if it's a high-end exhaust with good flow.
