Description
Hard starting is often caused by voltage drop to your ignition coil during cranking—a problem that compromises cold starts and wastes cranking cycles. The COMP Cams Fast Start Boost Relay (F-5030) solves this by delivering full battery voltage directly to your single-fire coil when you need it most, eliminating the struggle and ensuring reliable ignition every time you turn the key. If you’re running a high-performance or custom ignition system, this relay is essential insurance against starting issues that can plague dedicated builds.
