Help deliver ignition voltage to each cylinder in turn with the Standard Ignition Distributor Cap JH-188, a replacement cap that routes high voltage from the rotor to each spark plug wire terminal. It fits many vehicles, among them the 1996-1997 Toyota RAV4, 1992-1996 Toyota Camry and 1994-1999 Toyota Celica, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for engine details and the full list.
- Quality control: As a global manufacturer of original equipment ignition products, Standard Ignition keeps quality control in-house through the whole manufacturing process, from components to the finished product.
- Cap material: Made of high dielectric strength, glass/mineral reinforced polyester resin for less carbon tracking and greater resistance to electrical breakdown.
- RFI resistors: Used where specified to help suppress radio static and potential ECU-damaging spikes.
- Terminals: Solid brass terminals are used where available for better connections and greater resistance to electrical pitting and corrosion.
Distributor caps wear with heat and age. Signs this part may need replacing include misfires, hard starting, a rough idle, visible cracks, carbon tracks inside the cap, or corroded terminals. Other ignition parts can cause the same symptoms, so diagnose the cause first. If a worn cap is the cause, JH-188 replaces it. During installation, move the spark plug wires one at a time from the old cap to the new one to keep the firing order correct.

Frequently Asked Questions
What does a distributor cap do?
It covers the distributor and routes high ignition voltage from the spinning rotor to the correct spark plug wire terminal, so each cylinder fires in its turn.
Is JH-188 a direct-fit 1992-1996 Toyota Camry distributor cap?
It is listed as a direct-fit replacement for the 1992-1996 Toyota Camry. The "Vehicles it fits" section shows the engine details for each listed vehicle.
Does this 1994-1999 Toyota Celica distributor cap also fit the 1996-1997 Toyota RAV4?
Yes. It is listed for the 1994-1999 Toyota Celica and the 1996-1997 Toyota RAV4, and the "Vehicles it fits" section covers the other listed applications.
What is this distributor cap made of?
Standard Ignition makes its distributor caps from 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?
Common signs include misfires, hard starting, a rough idle, cracks, carbon tracks, or corroded terminals. Diagnose the cause first, because other ignition parts can cause the same symptoms.
