Ignition Box, "Second Strike", Pertronix

Second Strike Ignition Supplement with Rev Limiter by PerTronix®

Adds a timed CD spark after the primary inductive spark.

The PerTronix® Second Strike keeps a compatible inductive ignition as the primary spark source and adds a capacitive-discharge spark after it. The second spark can be set 2-18 crankshaft degrees after the first, combining inductive burn time with a later high-energy discharge throughout the rpm range. This supports combustion efficiency and helps reduce plug fouling. An integrated rev limiter reduces output by distributing skipped sparks across cylinders. The supplement works with most compatible OE or aftermarket non-CD ignitions and many modern tachometers without an added interface.
