The S&S Off Road Division KRX Turbo Kit is now available for the 4 seater! How does a 50 percent gain in Horsepower with 0-60 in 7s vs the factory 11.5 seconds sound? This kit includes a massive fan cooled air to air intercooler (others do not) as well as 9:1 compression pistons that allow for 10 psi of boost (double of any competitors kits) and a pre-loaded PV3 tuner. To top it off, our kit also includes a tuned plenum (the factory unit can't handle boost), larger injectors, fuel rail, and even correct temp plugs, all in a factory-style package with hundreds of hours of durability testing behind it.
