What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire conditions related to plug wear or incorrect gap
• Reduced throttle response from weak ignition performance
• Service intervals where OE-style replacement is required

Installation Notes

• Verify the application by year, make, model, and engine configuration before installation.
• Confirm the plug gap is set to 0.044 in. where required by the vehicle notes.
• Use the correct torque procedure for the cylinder head material and plug seat type.
• Inspect ignition wires, coils, and boots during spark plug service to avoid repeat misfire issues.
• For the 1984-1988 Nissan 200SX Exhaust Side application, follow the listed dual-plug fitment notes and gap specification.
