COVID-19 Update: Our website offers seamless ordering anytime, and with the exception of business critical personnel, the majority of our customer service, call center sales staff marketing and related support are officially connected and working from home as of Monday, March 30, 2020. Like most fulfillment centers, you’ll likely experience some delays in shipping, as our Warehouse team is running at reduced capacity. We are continuing to take extra precautions with additional cleaning and sanitization in our fulfillment center. With the new government guidelines in place, we hope to be back to normal sometime in May. For additional details, click here. Show More… Show Less…

The efficient components use less current and produce more power than capacitive discharge ignition systems. Box features a locked and sealed wiring connection and the 6AL includes a built-in soft-touch rev limiter complete with adjustable rotary dials for added protection. The control box comes with all necessary wiring, vibration dampers, instructions and hardware.
