BDFHYK Ignition Coil UF549 for Nissan Altima Rogue Sentra Versa — Direct-Replace, OE-Style Chip

The BDFHYK Ignition Coil Pack UF549 is a direct-replacement ignition coil engineered to restore reliable spark delivery for compatible Nissan, Infiniti and Suzuki models.

If your vehicle is showing signs of misfires, sluggish starts or reduced performance and it accepts UF549-style coils, this BDFHYK unit is built as a straightforward swap using high-grade materials and the original-style internal chip. Manufactured with durable polymers and designed to match OE electrical characteristics, the coil aims to deliver consistent spark timing and long service life when installed alongside properly maintained spark plugs.

How does this coil improve starting and engine smoothness?

The BDFHYK coil restores consistent high-voltage output to each spark plug, which helps reduce misfires and rough idling caused by weak or inconsistent ignition. Because it uses a factory-style chip and optimized windings, it closely matches the original coil’s performance curves for smoother combustion.

• Direct-replacement form factor for simple installation.
• Original-style internal chip for matched firing characteristics.
• High-grade PBT/PPO housing materials resist heat and corrosion.
• Intended to reduce rough idle, misfires and hesitation when paired with good spark plugs.

Which vehicles and part numbers is this coil compatible with?

This coil is designed to fit many Nissan, Infiniti and Suzuki models across model years listed by the manufacturer—confirm fitment before purchase. It is cross-referenced to several OEM numbers so you can match it to your vehicle’s existing coil part number.

• Common fitments include Nissan Altima (2007–2018), Rogue (2008–2020), Sentra (2007–2019) and Versa (2007–2012).
• Also fits select Infiniti models (for example QX60 and QX70 ranges) and Suzuki Equator years noted by the supplier.
• Cross-references to OE numbers such as UF549, 22448ED000 and others for easy verification.
• Always confirm compatibility by year, make, model and original coil part number.

What are the key construction and durability features?

BDFHYK uses PBT sourced from Germany and advanced PPO materials to improve the coil’s resistance to heat, wear and environmental corrosion. The robust housing and internal design reduce failure modes common to ignition coils when exposed to engine bay temperatures and vibration.

• Reinforced polymer housing for thermal stability and chemical resistance.
• Factory-style electronic chip installed for consistent electrical performance.
• Corrosion-resistant terminals and secure plug fit to minimize connectivity issues.
• Manufactured by an established parts supplier with in-house production and quality checks.

How easy is installation and what should I check after fitting?

This coil is a direct replacement with the same mounting and electrical connections as the OE unit, so installation is typically straightforward for anyone comfortable with basic engine work. After installing, inspect for secure electrical connectors, proper seating on the spark plug and perform a quick engine run to confirm smooth idle and absence of diagnostic trouble codes.

• Remove engine cover (if applicable) and unplug the old coil, then swap in the BDFHYK coil.
• Ensure connectors click into place and boots seat fully on the spark plug.
• Check for CEL or misfire codes after a test drive; re-torque any fasteners if needed.
• Replace aging spark plugs to prevent premature coil stress and extend coil life.

Who is this for: The BDFHYK Ignition Coil Pack UF549 is intended for vehicle owners and independent mechanics who need an OE-style replacement coil for compatible Nissan, Infiniti or Suzuki models. It’s well suited to drivers seeking a durable, cost-effective replacement that matches original electrical characteristics—especially when spark plugs and related ignition components are maintained to factory recommendations.
