Has anyone used these?....Do they really help that much?...They say that they give you new jets and all but do they give ya some step by step instructions or do you need to take to a shop.....Also on those Hot Seat nerf bars to they give ya the pegs too?

 

I could be wrong, but I think you mean the HPD aluminum airbox. Anyway, they work if you're looking for increased flow capabilities coupled with water protection. Also loose a few pounds off the machine to boot.

 

Ya could be i was lookin at both sites and many others this mornin when i seen it...Does it give any kinda hp boost do you think?

 

HPD claims about 2hp with there airbox kit and HPD are a pretty good after market company and do there research so there claims would be pretty accurate.
