HQPASFY Ignition Coil & 4 Iridium Spark Plugs Kit UF549 — Direct-Fit for Nissan/Infiniti 1.6–2.5L, Longer Life

HQPASFY Ignition Coil UF549 with a set of four iridium spark plugs replaces worn coils and plugs to restore reliable spark and steadier engine running for compatible Nissan, Infiniti and select Suzuki models.

If your vehicle shows rough idle, misfires, or reduced throttle response, failing ignition components are a common cause. This bundle pairs one UF549-style ignition coil with four iridium spark plugs engineered for higher conductivity, thermal resistance, and longer service life than stock units prone to high internal resistance or rapid insulation breakdown. The kit is built to match OE mounting and electrical fitment for a wide range of Nissan, Infiniti and Suzuki engines, letting you swap components without major modification.

Which vehicles and engine sizes will this ignition coil and plug set fit?

This kit covers many model years and engine sizes across Nissan, Infiniti and Suzuki lines. It’s targeted at 1.6L–2.5L petrol four-cylinders and some 5.0–5.6L Infiniti V8 applications where UF549-style coils are specified. Always verify your vehicle’s OEM part number before purchasing.

• Common Nissan fitments: Altima, Rogue, Sentra, X-Trail, Frontier, NP300, Tiida, Versa, NV200/350, March, Pathfinder and Urvan models.
• Infiniti & Suzuki examples: Q70/Q70L, QX60, QX70 V8 and select FX/M56, plus Suzuki Equator 2.5L where noted.
• Reference OE numbers: UF549, 22448-JN10A, 22448ED000 and related cross-references for confirmation.

How does this coil-plus-iridium-plug combination improve ignition performance?

The coil provides consistent high-voltage output and the iridium plugs maintain stable spark over longer intervals than conventional electrodes. Together they reduce misfires, improve combustion repeatability and support smoother acceleration without altering engine management.

• High-conductivity copper winding reduces electrical losses during spark generation.
• Iridium electrodes resist wear and preserve gap precision for consistent firing.
• Heat-tested design maintains stable output under elevated temperatures and vibration.

What should I expect during installation and ongoing maintenance?

Installation is a direct swap where the UF549-style coil and standard spark plug threads match factory locations; basic hand tools and a torque wrench are sufficient. Inspect the coil boot, connector and plug threads for corrosion during install, and replace the set in matched intervals to keep firing consistent.

• Direct-fit electrical connector and mounting; no splicing required.
• Use correct torque values for coils and plugs to prevent damage or mis-seating.
• Check ignition boots and wiring harness for wear when replacing components.

What warranty and part references come with this product?

HQPASFY backs this component with a 12‑month warranty covering manufacturing defects. The product lists many cross-reference numbers so you can match it to OEM parts when confirming fitment.

• Manufacturer warranty: 12 months for defects and workmanship.
• Cross-reference numbers included: UF549, 22448-JN10A, 22448ED000 and others.
• Sold as one ignition coil (UF549 style) plus four iridium spark plugs per kit.

Who this is for: Drivers and independent mechanics who own compatible Nissan, Infiniti or Suzuki vehicles and want a cost-effective replacement bundle to restore reliable spark, reduce misfires and extend time between service intervals. Ideal for those replacing a single failed coil plus plugs or refreshing the ignition system with components that match factory fit and electrical characteristics.
