Hot Cams Stage 3 Intake Camshaft for Yamaha YFZ450 2004-2009 4097-3IN

The Hot Cams Stage 3 intake camshaft is purpose-built for YFZ450 racers who demand measurable gains in mid-range torque and peak horsepower without compromise. This is a bolt-on upgrade that works seamlessly with your stock valve springs, letting you extract significantly more power from your engine without fabrication work or expensive modifications. Whether you're chasing faster lap times or dominating trail riding, the Stage 3's Improved Throttle Response (ITR) technology sharpens your throttle feel and delivers the aggression your quad demands.

The engineering here is straightforward: HOT CAMS profiles the lobes to optimize valve lift and duration across critical RPM ranges, generating measurable power gains from mid-range acceleration through top-end pull. Drop it in, sync your timing, and feel the difference immediately. This is the kind of fundamental upgrade that separates competitive machines from stock ones.
