Product Description

A single overhead camshaft provides precise valve timing for maximum power with minimum weight. This 6-valve, SOHC design efficiently exchanges intake and exhaust gases for responsive power and fuel efficiency. All air entering the engine block of the F40A is routed through a single throttle valve to ensure the precise amount of air necessary for optimum power and fuel efficiency. The air silencer box reduces intake noise and air turbulence for smooth, quiet operation. Three individual compact electronic fuel injectors deliver the exact amount of fuel needed for optimum performance and economy. Controlled by the Engine Control Module via input from an array of on-engine sensors, their location just above the intake valves enhances fuel atomization, resulting in more efficient combustion.
