Sierra 18-5358 Distributor Cap, Replaces Volvo Penta 841263, for AQ145/AQ151 Stern Drive Engines, White

The Sierra 18-5358 Distributor Cap is a direct-fit ignition component designed for Bosch-style distributor applications on Volvo Penta stern drive engines, specifically the AQ145A, AQ145B, AQ151A, AQ151B, and AQ151C engine models. The distributor cap seals and protects the distributor's internal contacts while directing high-voltage spark from the ignition coil to each spark plug in firing order, making it a critical part for reliable engine starting and smooth running. This cap is finished in white with a machined metal construction and uses a twist-on closure for secure, tool-free installation and removal during routine maintenance or tune-ups.

Each Sierra 18-5358 cap is built to meet or exceed the performance of the original equipment part it replaces, making it a straightforward swap for a cracked, worn, or corroded distributor cap. It is interchangeable with several commonly referenced cross numbers, so boat owners searching by CDI, GLM, Mallory, or Volvo Penta part numbers can confirm they are ordering the correct replacement. One distributor cap is included per package.
