    Kawasaki 250x aftermarket intercooler and hks blow off valve

    Hey. I want to install an intercooler from frozenboost.com and install a hks bov to it for racing and pleasure rides. I know I have to get the intercooler made to fit because I know others have done it and it works but I am curious to know if the bov will work because I was told there is a difference between the stock Kawi relief valve and the hks bov. Love the sound of the hks and I liked how it worked on my old fzs. Just not sure if it would work the same way on a 250x. Really don't want to waste money on something that won't work so please reply to let me know what's best for me to do.

    The thing is that i race and the stock intercooler that i had has a leak which can cause you to lose power and become a pain in the ass. Other teammates run vortec chargers with a intercooler that can handle more pressure, is lighter, cheaper, and more reliable. The stock intercoolers are too expensive and costly to replace especially with the salt water conditions i ride in. Frozen boost has a replica to the vortec that works great but i just want to know if a hks bov can work because i know that the vortec intercoolers and stock intercoolers require a different type of bov.

    proper maintenance, rerouted cooling lines on the stock ic setup, a blocked of BOV, and properly functioning bypass valve should give you all the reliability you need in a race setup.

    look at the welds on a frozenboost intercooler and you'll see why its cheaper.......

    i've had an ultra for the last 8 years.... never had an issue with the intercooler whatsoever and it was raced hard for the first 3.5 years of its ownership.
