This OE Match spark plug set contains six identical spark plugs, each manufactured to OE-equivalent specifications to ensure consistent combustion and dependable ignition across all cylinders. Built to withstand high combustion temperatures and sustained electrical load, these plugs help maintain smooth engine operation, stable idle, and reliable power delivery.

Replacing spark plugs as a complete set is essential for balanced ignition and even engine performance. Over time, worn or mismatched plugs can cause misfires, hesitation, increased fuel consumption, and uneven combustion. This OE Match pack of six provides a cost-effective solution for routine servicing, tune-ups, or ignition maintenance while maintaining OE-level performance and fit.

 All plugs are direct-fit replacements and install without modification.

Function:
•  Provides reliable ignition for all six cylinders
•  Supports smooth idle and responsive acceleration
•  Helps maintain fuel efficiency and balanced combustion
•  Supplied as a complete engine set for correct servicing

Spark plugs degrade over time due to heat and combustion stress. Replacing all six plugs together ensures consistent ignition timing across cylinders, prevents misfires, restores smooth performance, and helps protect catalytic converters from damage caused by incomplete combustion. Using an OE Match set ensures reliable performance without compromising fit or function.

When to replace:
•  Engine misfires or rough idle
•  Reduced throttle response or loss of power
•  Increased fuel consumption
•  At manufacturer-recommended service intervals
•  During routine tune-ups or ignition system servicing
