Yamaha YZF-R3 Superbike/Supersport Velocity Stacks 2015/Current
$369.99 – $459.98
The OEM Air box on the Yamaha R3 contains two different length velocity stacks, one long, one short and a small intake tracks which limits the air intake into the engine,again remember this is a commuter designed motorcycle.
The performance difference with the Spears Racing Yamaha YZF-R3 Velocity Stacks compared to the stock is dramatic.
Here’s a dyno comparison with a stock motor(OEM), stock air box vs stock motor with a BMC air filter,M4 exhaust and a power commander five (PCV) vs stock motor with a BMC filter, M4 exhaust and a power commander five (PCV) modified air box (See Install ) with Spears Racing’s velocity stacks. You can see the power band carries strong through the complete power and starts a separation from the stock run at 9800 RPM’s and continues to make more power to the red line instead of falling off at 10,700 and we don’t lose any important midrange power. The increase from 10,500 to the rev limiter is massive both with RWHP and Torque.
