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.
