The Classic Triple SD is a variation of the NO BLACK BOX system compatible with Miniature coils only. The coils are small enough to fit under the tank in some installations. The dwell time with this system is matched to the smaller coils for higher spark energy.
Suits the Rob North BSA Rocket 3
The mini coils, HT leads and caps are INCLUDED in this kit.
Please note the two versions of the Classic Triple are not interchangeable.
