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!
