I know there's like many other posts like this in the forum, but they're not really in depth and not helping me make a educated decision. Basically, I am getting my stock ECU refreshed by Pep's Performance, and I have the option to purchase a FCI intake along with it for my 21 yfz450r. I would've liked the freedom to upgrade the intake in the near future, but I have to make the decision now. Is it really worth the $325? I only trail ride not race or anything like that. If so, what kind of performance difference will I feel? Im not really into dyno or horsepower numbers etc just care about if I really feel a difference rather than removing my stock airbox lid.
