Thousands of hours of research, hundreds of designs and dozens of tested vehicles, we make sure all and every kit performs to a world class standard.

smoother idle

By eliminating cylinder cross-talk, very aggressive cams can be run without low RPM stalling and with reduced lumpiness.

Instant throttle response

By allowing each cylinder to consume the same and maximum amount of air, your engine can be run at its optimum performance.
