A bad DISA valve can cause a variety of issues, from a loud racket in the engine bay, hesitation at low rpm and a rough idle with lean codes. If the valve is making a loud noise, we recommend replacing it as soon as possible. It is possible for the pin holding the flap to be sucked into the motor causing serious damage. Very easy to replace, just need to undo the 4 bolts holding it to the intake manifold.

Increase the power of your vehicle by utilizing a water/meth injection kit. The purpose of water/meth injection is to reduce combustion temperatures and allow you to run higher boost pressures on pump gas. When using meth injection, pump gas will resist detonation much better because the methanol essentially raises the octane rating of the fuel and will allow you to run much more aggressive street tuning. This AEM kit has more features and components than any other comparably priced injection kits on the market. 1 Gallon tank with built in low level switch Boost referenced progressive controller ?Boost Safe? readiness safety system Check valve integrated into nozzle to prevent unintended fluid flow One injector and two nozzles to cover a wide range of HP levels High Pressure 200psi Recirculation-style pump Progressive Controller: Start Injection Boost 1-11psi.
