Did you view their diagram of how it works? They want you to believe that adding a RESTRICTION into the intake side of the engine will actually increase the efficiency... You're better off adding another $100-$200 and getting your head ported, it'll actually make a difference.

Aside from the occasional anecdotal "butt dyno" improvements often shared by people with questionable reliability/knowledge I have yet to see any evidence that they work at all let alone are worth the cost.

Your money is best spent elsewhere.

Think about it for a moment... with every bike/quad manufacturer hot to try to outdo their competitors, if this added any real power, don't you think they'd be using it? Damn thing should only cost about $2 to build into their existing intake boots...

It's fake. It's crap.

I've seen these things for years and have talked to people that have used them, if they work they give you a slight edge on the bottom end on the throttle, but hurt in the top end because of the restriction they cause in the throttle bore............:)

BUT it isnt worth it..................:D

"SCARY FAST POWER NOW"
sounds like a description of a willykiller 3-plugger to me! :)

rukind, I want that same design as you have on your quad, but red instead of the yellow.
I am going to mess with it in photoshop. I have had a few people ask about more red. let me see what we "chris" can do for me. If anyone find a cool picture send them to me.

Thanks, Willy - I chalk that up to a lot of the other things that give some extremely small, marginal improvement - If I'm racing and I need that 1/100th of a second to win, I'll do everything I can. If I'm riding for pleasure, I'll never notice the difference.

i hear finding an old sock and stuffing it in your intake may increase power and its free! Only thing scary about it is how fast your bike is without it. lol. im sure in tiny print its somewhere....

i mean thats why fcrs have better throttle respons/power no? no butter fly restriction and no vacuum slide. Its why yamaha went with a 42mm carb stock on the 2012 yfz instead of 39 fcr.
