Keep ignition voltage routed to the right cylinder with the Standard Ignition FD-148 Distributor Cap, a replacement cap made of high dielectric strength, glass/mineral reinforced polyester resin. It fits many vehicles, among them the 1976 Ford F-150, 1987-1990 Jeep Wrangler and 1977-1983 Jeep Cherokee, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
The distributor cap covers the distributor and carries high voltage from the ignition coil to the spark plug wires, with the rotor passing the spark to each outer terminal in turn. Cracks, carbon tracks or worn terminals can disrupt that path. If a failing cap is behind a misfire, rough running or a hard start, this cap replaces it.
- Cap material: High dielectric strength, glass/mineral reinforced polyester resin, designed for less carbon tracking and greater resistance to electrical breakdown.
- Quality control: Standard Ignition is a global manufacturer of original equipment ignition products and maintains quality control through the whole manufacturing process, from componentry to finished product.
- Development: Draws on decades of Standard Ignition research and development in distributor caps and rotors.
Before you install it, consult the vehicle service information. Transfer the plug wires to the new cap one at a time so each wire stays in its original position.

Frequently Asked Questions
Is the FD-148 the right distributor cap for a 1987-1990 Jeep Wrangler?
The 1987-1990 Jeep Wrangler is one of the listed applications for the FD-148. Check the "Vehicles it fits" section for engine details.
Does it also fit the 1977-1983 Jeep Cherokee or 1976 Ford F-150?
Yes. The listed applications include the 1977-1983 Jeep Cherokee and the 1976 Ford F-150, and many other vehicles are listed in the "Vehicles it fits" section.
What does a distributor cap do?
It covers the distributor and carries high voltage from the coil to the spark plug wires. The rotor sends the spark to each outer terminal in turn.
What is the FD-148 cap made of?
It is made of high dielectric strength, glass/mineral reinforced polyester resin, which is designed for less carbon tracking and greater resistance to electrical breakdown.
What are signs a distributor cap may need replacing?
Look for cracks, carbon tracks, corroded or worn terminals, misfires, rough running or hard starting. Diagnose the cause first, because other ignition parts can cause the same symptoms.
