"I've been told that there is no performance gain from installing the K&N filters. There is a reason all 3 throttle bodies are "attached" together via the same
air horn. Triumph has done much testing and end result was that they all need to share the same air flow plenum."
Today I was told the same thing as well as something about the O2 sensor will just ad more fuel making everything rich all the time thus wasting fuel. I was told the way it would work would be to delete the O2 sensor and install a power commander and have it tuned that way. Looks like I'll just be doing the TORS with a CAT delete and downloading the TORS tune from Triumph. It's funny today while at the stealer I actually heard a a R3 with this setup and it sounded badass. I have found a NIB set of TORS if I want to spring for them. Money is a little tight at the moment, but I'd hate to miss an opportunity to get a set.
