Standard Ignition Distributor Cap P/N:JH-155
Standard Motor Products
Keep spark delivered to the right cylinder with the Standard Ignition JH-218, a direct-fit 1994-1998 Toyota Supra distributor cap that also fits the 1993-1997 Lexus GS300 and 1992-1997 Lexus SC300. The cap carries high-voltage ignition current from the spinning rotor to each spark plug wire terminal in the engine's firing order. See the "Vehicles it fits" section for engine details.
Signs a distributor cap may need replacing include cracks, carbon tracks or corroded terminals inside the cap. A worn cap can contribute to misfires, hard starting or rough running. Other ignition or fuel faults can cause the same symptoms, so diagnose the cause before replacing the cap. When you install the new cap, inspect the rotor as well.

Will this distributor cap fit my 1992-1997 Lexus SC300?
The JH-218 is listed as a direct-fit replacement for the 1992-1997 Lexus SC300. The "Vehicles it fits" section shows the engine details for each listed vehicle.
What does a distributor cap do?
It carries high-voltage ignition current from the spinning rotor to each spark plug wire terminal, so each cylinder gets spark in the engine's firing order.
What is the Standard Ignition JH-218 made of?
It is made of high dielectric strength, glass/mineral reinforced polyester resin. Standard Ignition uses this material to reduce carbon tracking and resist electrical breakdown.
What are signs a distributor cap may need replacing?
Look for cracks, carbon tracks or corroded terminals inside the cap, which can contribute to misfires, hard starting or rough running. Other faults can cause these symptoms, so diagnose first.
How do I install the new distributor cap?
Move the spark plug wires from the old cap to the matching terminals on the new cap one at a time to keep the firing order. Follow the vehicle's service information for the full procedure.
