Wells 5D1131 Distributor Cap - Ignition Distributor Cap Replacement

The Wells 5D1131 Distributor Cap is a replacement ignition distributor cap. It is built to restore reliable spark distribution in distributor-equipped engines. The cap receives high-voltage secondary current from the coil through the rotor. Each ignition wire attaches to a tower on the cap, and the wires carry that current to the spark plugs.

Key Features:

• Designed to meet or exceed OE specifications in form, fit and function
• Routes secondary ignition voltage from the rotor to each spark plug wire
• Replaces a worn, cracked, carbon-tracked or corroded distributor cap
• Made by Wells Vehicle Electronics, a supplier of OE and replacement vehicle electronics

Replace the distributor cap when the towers or terminals show oxidation or corrosion. This wear raises secondary resistance. It can cause misfires, rough running, reduced fuel economy, a check engine light or a failed emissions test. Many technicians replace the rotor at the same time as the cap.
