The British Customs Airbox Removal Kit

Air-cooled Triumph models made before 2016 come out of the factory with an air box designed to restrict air flow to the engine. Our airbox delete kit replaces this restriction with two high flow K&N air filters to free up the flow of air, resulting in performance differences you can feel instantly with a proper tune.

Through the testing we’ve done on our own bikes, we’ve ensured that our air box removal kit is the most complete on the market. Included in the kit is an aluminum battery box with all the necessary mounting points to refit the factory components, and the industry leading K&N air filters are washable and mount directly to the end of the carburetors or fuel injection housing.

Tuning Note: Airbox delete kits for carbureted models will come with a Jet Kit for rejetting, and a support brace (due to differences in manifolds on carbureted bikes). If your model is fuel-injected, we recommend getting your bike remapped. See our Tuning Guide for more details. 

FEATURES

  • Increased airflow means more horsepower
  • Improved throttle response
  • Designed to work with or without side covers 
  • Includes Jet Kit *carbureted models only

JET KIT INCLUDES

  • 135 Main Jet (Qty 2)

CALIFORNIA DISCLAIMER

Each state has its own emissions and inspection requirements.  In California, this is managed by the Air Resources Board (CARB for short).  CARB has determined that certain aftermarket motorcycle parts are not legal for sale or highway use in the state of California. Items subject to this determination include certain exhausts, fuel controllers, and other parts that might affect a vehicle's emissions.

British Customs has determined to the best of its ability which items are CARB approved and which items are not - items that are not CARB approved are not able to be shipped to addresses in California or used for on-road use in California. 

Items that are not CARB approved may still be utilized in the state of California, provided that they are not used on a public road (i.e. only used on a closed course or offroad).  At this time, British Customs cannot verify if a product is used for closed circuit or off-road use and cannot ship to addresses in California.  

This product is not legal for sale or highway use in the State of California due to CARB regulations. British Customs will not ship CARB restricted products to California customers. Orders of CARB restricted products by California customers will be refunded and the order will be canceled.

5/5 should have bought this sooner!

This airbox removal kit is a must for the Bonneville. I was on the fence after reading on forums that this didn't really do much for the bike and that it wasn't worth the headache blah blah... Just do yourself a favor and get it because the stock airbox is extremely restrictive. This along with the predator pros really do transform the bike to what it should have been like from the factory. I have not tuned the ECU yet but right off the bat I experienced an increase in power and the whole bike just sounds so much better with that induction growl.

Highly recommend this! (easy to install just watch the YouTube video by BC) cheers!

Nice weekend project

I purchased and installed the airbox removal kit as part of my performance upgrades. I followed the instructions BC has in their YouTube video, which are spot on. Everything went without a hitch. Installation took a little longer than expected because I didn't have a few things needed like multipurpose grease, anti seize and a 13mm box end wrench. So being prepared and having everything you need before you start will save time. Otherwise, like all BC bolt on parts, the quality is a 10, fit and finish is a 10, customer service is a 10.

Have just installed this intake kit on 900efi thruxton, it has transformed the bike. Had BC predators for years and they were an excellent upgrade, but this intake kit took it to another level of performance and sound. Be advised, this is a minimum 3 hour job, if you’re good....5 if you’re not. So take that into your cost computation. In addition, you’ll need to pay for a remap. So, actual cost to purchase kit and have installed will be around $600-800 USD. That being said, it’s absolutely worth it...mid and especially high rpm acceleration has increased noticeably, along within a nice induction growl. I rode my bike around for years, very happy with my slip ons, but that was a mistake...you need intake to fully take advantage of exhaust and you need a remap to take advantage of the hardware. Highly recommend.

I just completed the air box conversion install coupled with removing the AIS (air inject system) very simple process. Results so far, significant drop in running temperature, Idle speed can be screwed down to 7-8 rpm, over all the bike is very very smooth the jerky on / off throttle has completely gone, Is there an increase in performance....its not notable. I am having the bike go in for the first service this week, will be interesting to see if they re-map and if so will there be a significant difference in performance yet be be seen, either way I feel the money was well spent, one more thing I have a set of arrows two into one, so not only can the bike freely exhale it can now BREATH great products BC.

I have a 2016 Thruxton with Arrow pipes and fitted this kit last night.

The printed instructions were only satisfactory, but the BC youtube how-to is excellent. Overall, the job took an hour and was very straightforward.

The only disappointment was that there was no collar supplied for the small crankcase filter (they are for the 2 large filters).

The bike is way more responsive, powerful through the mid-range and the exhaust note from my Arrows have gone from throaty to almost like a death metal vocalist. Well worth the money.

Cheers from NZ

Scott.
