Stage 1 Kits: Designed for ATV’s with stock engines using the stock airbox, air filter and stock or after-market exhaust. Improve throttle response and driveability. Power increases of approximately 5% throughout the entire power range
Stage 2 Kits: Designed for ATV’s with stock or mildly modified engines using well designed stock or aftermarket exhausts with a modified airbox and stock or replacement air filter. For applications where individual air filters cannot be installed and where airbox modifications improve overall engine performance. A power increase of 8% can be achieved in most cases
Stage 3 Kits: Designed for ATV’s with stock or mildly modified engines using individual air filters and a stock or aftermarket exhaust. In most cases power increases 10-15%; driveability may be compromised in short-stroke high RPM motors. On some modern engine and airbox designs, individual filters and proper jetting offer no performance improvement and compromise driveability (stage 3 kits are not available in such cases)
