Which Nissan and Infiniti models will this coil and spark plug kit fit?

This kit covers a broad range of Nissan and Infiniti vehicles across multiple model years and engine sizes. It’s designed for four-cylinder Nissan models as well as several V8 Infiniti models—check the provided OE numbers to match your vehicle precisely.

How do these coils and iridium plugs improve engine performance?

Replacing aged ignition coils and spark plugs helps restore strong, consistent sparks that support efficient combustion. That can reduce rough idling, lower misfire incidence, and make throttle response crisper without additional tuning.

• Iridium plugs maintain a precise gap longer for consistent ignition.
• High-voltage coils convert battery voltage into the energy needed for stable combustion.
• Factory testing and OEM-matching form, fit, and electrical characteristics ensure plug-and-play replacement.

What should I check before ordering to ensure a correct fit?

Confirm compatibility by comparing the part numbers printed on your existing coils or the numbers listed in the product’s OE reference. Check model year, engine displacement, and connector style to avoid returns and installation delays.

• Compare UF549, 22448-1KT1A, 22448-ED000 and other cross-reference codes with your current parts.
• Match engine type (L4 or V8) and model year listed in the compatibility table.
• If unsure, provide your VIN to the parts supplier or consult a trusted mechanic.

Is installation DIY-friendly and what comes in the package?

The set is intended as a direct replacement suitable for experienced home mechanics and professional shops. Installation complexity depends on engine bay accessibility and whether ignition coil access requires removal of other components.

• Package includes four ignition coils and four iridium spark plugs—everything needed for four cylinders.
• No extra wiring or modules required; designed to plug into existing connectors.
• Basic hand tools and a torque wrench recommended; follow OEM torque specs for spark plugs and coils.
