What is the best way to build up a 3.0 without major alterations to the engine on a 2004 Ranger XLT and without hurting the warranty? I have heard about a SpiralMax Twister thingy you put in the air duct vent that will boost power but not sure if this is a glimick or what.
Also mufflers I have heard boost horsepower. This 3.0 is rated at 154 horses stock and I would like to get up to at least 200+ any suggestion please?
