If your ride’s powered by a 4-, 6- or 8-cylinder that runs on alcohol or is fitted with a turbo/blower, then an MSD 8-Plus Ignition Box is the replacement starter you need to deliver unparalleled starting power. With a core group of hardcore racers and pullers to back it, you’ll know you’ve chosen wisely when you turn the key.
Offering a superior output to previous iterations, the 8-Plus Ignition Box features a built-in, two-step rev control, which allows you to switch between two rev limits without extra wiring or housings. Another way in which it differs is that it includes a smaller housing with improved efficiency and internal components.
Capable of firing two coils at once for dual-plug racing setups, your MSD 8-Plus Ignition Box is backed by a limited warranty.
