Keep high-voltage spark routed cleanly to every plug wire with a new 1991-1997 Toyota Previa distributor cap from Standard, part number JH-189. It is a direct-fit replacement for the 1991-1997 Toyota Previa. Engine-specific details are on the Buyer's Guide tab.
The distributor cap receives voltage from the ignition coil. As the rotor turns beneath the cap, that charge passes to each spark plug terminal in firing order. Over time, heat, moisture and electrical arcing can crack a cap, leave carbon tracks on its inner surface or corrode its terminals.
- Quality control from start to finish: Standard is a global manufacturer of original equipment ignition products. It maintains quality control throughout production, from componentry to the finished cap.
- Reinforced cap body: The cap is made from high dielectric strength, glass/mineral reinforced polyester resin.
- Designed to resist tracking: The resin is intended to give less carbon tracking and greater resistance to electrical breakdown.
- Decades of development: The cap draws on decades of Standard research and development in distributor caps and rotors.
Signs this part may need replacing: misfires, hard starting, a rough idle, or visible cracks, carbon tracks or corroded terminals inside the cap. Other ignition components can cause the same symptoms, so diagnose the cause first. If a worn cap is behind the problem, JH-189 replaces it.
