SYKRSS Ignition Coil Pack for Nissan & INFINITI — 4-Pack OE-Style Direct Fit, Durable Performance

SYKRSS UF549 4-pack ignition coil set replaces worn factory coils to restore reliable spark and smooth running for compatible Nissan and INFINITI 4‑cylinder engines.

This four-pack of UF549 ignition coils from SYKRSS is built as a direct OE-style replacement for many Nissan and INFINITI models. The kit is engineered to match original electrical and mechanical specifications while using upgraded internal materials for improved durability and consistent high-voltage delivery. Each coil is bench-tested before shipping and comes with a user manual and access to U.S.-based customer support.

Which vehicles will the UF549 coil pack fit?

These coils are produced to fit a broad set of Nissan and INFINITI applications. Confirm the exact fit by comparing OEM part numbers or consulting the model chart for year, engine size, and VIN-specific compatibility.

• Nissan: Altima, Sentra, Rogue, Pathfinder, Cube, Versa, NV200 (1.8L, 2.0L, 2.5L L4 applications)
• INFINITI: FX50, M56, QX60 (cross-referenced to multiple OEM numbers)
• Replaces numerous OEM references such as UE549, 1788369, 22448-ED000, 5C1753, C1696, and others

How does this coil pack improve running performance?

SYKRSS coils use enhanced internal components to maintain stable voltage and faster discharge compared with aged original coils. That leads to a more consistent spark, which helps maintain smooth idle, stable throttle response, and efficient combustion across driving conditions.

• Silicon steel cores and German copper windings for reliable high-voltage delivery
• Heat-resistant rubber boots and Japanese-grade epoxy for longer service life
• Bench-tested to reduce misfires and minimize rough idle or hesitation

Is installation difficult and what tools are required?

Installation is designed to be plug-and-play and mirrors the original coil layout—no modifications are necessary. A basic set of hand tools is usually enough, and many DIYers can complete the swap in about 15 minutes per coil depending on engine access.

• Typical tools: ratchet, socket set, and possibly a small extension
• Includes a user manual; no special programming or calibration needed
• Professional support available from SYKRSS if you encounter fit or installation questions

What quality controls and warranty support come with the coils?

Each coil undergoes bench testing for voltage stability and is manufactured using upgraded materials to exceed many factory specifications. The set ships with a customer support channel in the U.S. for compatibility or installation help.

• Strict bench-testing for consistent voltage across operating range
• Upgraded materials intended to extend service life over time-worn OE coils
• 4-coil kit packaged with manual and backed by SYKRSS support

Who is this for: The SYKRSS UF549 4-pack is aimed at Nissan and INFINITI owners who are experiencing ignition-related symptoms (misfires, rough idle, check-engine codes) or who want a cost-effective, higher-durability replacement for worn factory coils. It’s also suitable for DIY mechanics and professional shops seeking a direct-fit, cross-referenced replacement that installs without custom work.
