The Sierra 18-5361 Distributor Cap is a direct-fit replacement cap for New GM Module-in-Cap 4-cylinder distributors, including 3.0L LX applications. It is built from machined metal in a white finish and uses a twist-on closure for a secure, weatherproof seal over the distributor. As the cap that routes spark from the ignition coil to each spark plug in firing order, it is a wear item that should be inspected and replaced when it shows cracking, carbon tracking, or corroded terminal contacts, since a failing cap can cause misfires, hard starting, or a no-start condition.

The 18-5361 replaces OMC 986643 and is manufactured to meet or exceed the specifications of the original equipment part. It is compact, measuring 0.39 x 0.39 x 0.39 inches and weighing 0.21 pounds, and is sold as a single distributor cap ready to install in place of the original.
