If you're looking to unleash the full potential of your Triumph Modern Classic, the British Customs air box removal kit is a must-have. This simple upgrade allows you to ditch the restrictive factory air box in favor of two high-flow K&N air filters, for a significant boost in power and performance.

The British Customs Airbox Removal Kit

  • _ _

How does removing the air box increase performance? The OEM air box routes air intake through the stock snorkel (located underneath the left-hand side cover), which then flows through the restricted air box to the carburetors or throttle bodies. By removing the stock air box and installing two high-flow K&N filters directly onto the carburetors or throttle bodies, you'll ensure maximum airflow for optimal power and performance.

Whether you're hitting the open road or the race track, this easy upgrade will help you get the most out of your Triumph. So don't wait - make the switch today and experience the difference!

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)
  • 140 Main Jet (Qty 2)
  • 42 Pilot Jet (Qty 2)
  • Needle Shims (Qty 4)

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.

Note: If you're looking for the Battery Tray replacement alone, please view product here

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 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.

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.
