Keep spark voltage routed cleanly to each cylinder with the Standard Ignition Distributor Cap JH-240, a direct-fit replacement cap that covers the distributor and passes ignition coil energy on to the spark plug wires. It fits many vehicles, among them the 1999-2004 Nissan Frontier, 1996-2000 Nissan Pathfinder and 2000-2004 Nissan Xterra. See the "Vehicles it fits" section for the full list and engine details.
Inside the distributor, the rotor turns beneath the cap and delivers voltage from the center terminal to each outer terminal in turn, feeding the correct plug wire. Over time a cap can crack, build up carbon tracks, trap moisture or develop corroded terminals. Signs it may need replacing include misfires, rough running or hard starting, but those symptoms can have other causes, so diagnose the ignition system before replacing parts.

This part cross-references / interchanges with the following part numbers:
Is the JH-240 a direct-fit 2000-2004 Nissan Xterra distributor cap?
Yes. It is listed as a direct-fit replacement for the 2000-2004 Nissan Xterra, and the "Vehicles it fits" section shows every vehicle it fits.
Does this distributor cap also fit a 1999-2004 Nissan Frontier or 1996-2000 Nissan Pathfinder?
Yes. It is listed for the 1999-2004 Nissan Frontier and the 1996-2000 Nissan Pathfinder, along with other vehicles shown in the "Vehicles it fits" section.
What does a distributor cap do?
It covers the distributor and carries high voltage from the ignition coil to the rotor. The rotor then passes it through the cap's outer terminals to each spark plug wire.
What is the JH-240 made of?
Standard Ignition makes this cap from high dielectric strength, glass/mineral reinforced polyester resin. The manufacturer chose this material for less carbon tracking and greater resistance to electrical breakdown.
What are signs a distributor cap may need replacing?
Look for cracks, carbon tracks, moisture inside or corroded terminals, along with misfires, rough running or hard starting. These symptoms can have other causes, so diagnose them before replacing parts.
