ADJUSTABLE IGNITION MODULE FOR CARBURETED TWIN CAM & SPORTSTER

Twin Cam engines were designed with their performance potential in mind. No mater what modifications are made to the carburetor, exhaust or motor, the full effect will never be realized without the proper spark strength and exact delivery. Different combinations of performance products will require a distinct spark delivery and Crane's FireBall HI-4TC Adjustable Ignition Module is a dependable choice. This type of adjustability allows you to tailor fit the maximum spark advance curve (slope) without the damaging effect of spark knock.

• Provides a wide timing advance adjustment range for stock to highly modified engines
• Adjutable REV limit settings up to 9900 RPM in increments of 100 RPM. Sequence type limiter equalizes cylinder firing at REV limit to reduce popping and banging
