Standard Ignition Distributor Cap P/N:JH-197

$32.99

Description

Keep high-voltage spark flowing to every cylinder with the Standard JH-197 distributor cap, a direct-fit replacement for the 1990-1997 Lexus LS400 and 1992-1997 Lexus SC400. It covers the distributor and carries spark from the spinning rotor out to each spark plug wire terminal, and it helps keep moisture and dirt away from the ignition components inside. Engine details for each application are listed in the Buyer's Guide tab.

Reinforced housing: Made of high dielectric strength, glass/mineral reinforced polyester resin, which Standard specifies for less carbon tracking and greater resistance to electrical breakdown.
Built by an ignition specialist: Standard is a global manufacturer of original equipment ignition products and maintains quality control throughout manufacturing, from componentry to the finished product.
Decades of development: Draws on Standard's long history of research and development in distributor caps and rotors.

A distributor cap works in a hot, high-voltage environment. Over time it can crack, develop carbon tracks, or build up corrosion on its terminals. Signs it may need replacing include misfires, rough running, hesitation, or hard starting, especially in damp weather. Diagnose the ignition system to confirm the cap is the cause before replacing it.

Frequently Asked Questions

What does a distributor cap do?

It covers the distributor and carries high-voltage spark from the rotor to each spark plug wire terminal, so each cylinder receives spark in its firing order.

What is the Standard JH-197 made of?

Standard specifies high dielectric strength, glass/mineral reinforced polyester resin, which it states gives less carbon tracking and greater resistance to electrical breakdown.

Can I use this as a 1990-1997 Lexus LS400 distributor cap or a 1992-1997 Lexus SC400 distributor cap?

Yes. It is listed as a direct-fit replacement for both models. The Buyer's Guide tab shows the years and engine details for each application.

What are signs a distributor cap may need replacing?

Cracks, carbon tracks or corroded terminals on the cap are signs of wear. Misfires, rough running or hard starting in damp weather can also be signs, so check the ignition system to confirm the cause first.

Any tips for installing a new distributor cap?

Move the spark plug wires from the old cap to the new cap one at a time so the firing order stays correct. Inspect the rotor, and follow the vehicle service information for the procedure.
