EMP 300-01088 Distributor Cap, Replaces 41058, for Volvo Penta V8 190-415 HP GM Engines with Prestolite Ignition

The EMP 300-01088 is a distributor cap built for Volvo Penta V8, 190-415 HP GM marine engines equipped with Prestolite conventional ignition. It serves as a direct replacement for OEM 41058, restoring correct spark distribution to the ignition system after the original cap has cracked, corroded, or worn out from heat cycling and vibration typical in inboard engine compartments. The cap mounts to the distributor housing and routes high-voltage current from the coil to the correct spark plug wire terminal in firing order, so a worn or contaminated cap can cause misfires, hard starting, or rough idle on these GM-based marine V8s.

This part also cross-references with a range of aftermarket and OEM numbers used across Volvo Penta, Crusader, and other Prestolite-equipped marine ignition systems, making it easy to identify as the correct replacement regardless of which catalog number a buyer starts from. At 4 x 4 x 4 inches and 0.42 pounds, it is sized as a standard single-cap replacement, not a multi-part tune-up kit.
