Features may include: 

Impressive Power-to-Weight

• A proven 16-valve DOHC In-Line design, with four valves per cylinder maximizes efficiency and power. It also streamlines design, giving the F200 impressive power-to-weight.

Optimum Power

• Precision Multi-Point Electronic Fuel Injection and long-track intake system combine to maximize power and fuel efficiency across the line of In-Line Fours.

Better Charging

• With up to 50-amp alternators, our In-Line Fours provide plenty of power for a range of electronics, which comes in handy, now that they're all compatible with digital controls.

Quick Acceleration

• A 10mm Offset Crankshaft allows for larger intake volume design. Four tuned intake tubes boost torque in low and mid-speed ranges for quick acceleration.

Powerful Hole Shot

• The Composite Intake Manifold is a lightweight, compact design, making these engines very versatile. Long Tube Intake Tracks are tuned to increase airflow, boosting low-end and midrange torque. This means a more powerful hole shot and increased acceleration. Even with all this responsive power, an air silencer box and surge tank reduce air intake noise and air turbulence for smoother operation.
