What is a Stage 1 Upgrade?
The basic purpose of a Stage One is to modify the air filter, exhaust system, and fuel metering system to run as efficiently as possible, allowing it to breathe freely and, as a result, increasing the available power.
Moving more air and fuel through the engine is the fastest (and most cost-effective) ways to generate more power and torque. A free-flowing air filter and matching tuned exhaust will add performance you can really feel. Heavy breather and Stage 1 Free Flow Air Filters bring a big boost and a sweet-sounding exhaust system delivers power you can feel across a broad RPM range.
