4G93 DOHC 16v New Vehicle Performance Packages
After reading all of the options for your car, most people get to this point and ask - what can I do to my car without voiding my new vehicle warranty. RPW has produced a package that will provide the power improvements you are after without voiding the warranty on your vehicle. Before we go further though, lets clarify this position.
These products have been cleared via various Mitsubishi dealerships as permissible to alter. But what it fundamentally comes down to in any warranty claim is this. Can the modifications you have made to your vehicle be responsible for the failure of the product that has failed in the event of a warranty claim. In the majority of these cases the answer is usually no. But if you do fit a Nitrous Kit to your vehicle, destroy a piston then don't go back to Mitsubishi chasing warranty.
The suggestions below have been put together after many years of experience and are what we feel a safe package to go ahead with. Progressing in this order is also recommended so that you do not fit a component and get no power gains from it. Each modification done progressively will work in conjunction with the previous modification to give a subsequent gain. Changing this order will not produce the same result. Many of these products are also compatible with other higher level modifications later so you are not wasting your money now.
