BDFHYK ignition coil set of 6 UF349 compatible - direct-fit replacement, OE-style control chip

BDFHYK UF349 ignition coil set of six is a direct-fit replacement designed to restore reliable spark to compatible Nissan, Infiniti and select Suzuki engines.

This six-pack ignition coil kit is engineered for drivers who need a dependable aftermarket replacement for worn or failing OE coil packs. Manufactured using high-grade PBT and PPO materials and fitted with the original-style control chip, these coils aim to match factory fitment and electrical characteristics while resisting heat, wear and corrosion. Verify year, make and OE numbers to confirm fit before installation.

Which vehicles will these coils fit?

These coils are made to replace OE coil packs on a range of Nissan, Infiniti and some Suzuki models spanning early 2000s to recent years. Compatibility covers common sedans, SUVs and trucks, but fit depends on engine type and original part number.

• Nissan Altima (2002–2006), Maxima (2001–2008), Xterra (2005–2015)
• Pathfinder (2001–2012), Frontier (2005–2019), Murano (2003–2007)

• Suzuki Equator (2009–2012) and other models using UF349-compatible OEM numbers

How do these coils improve engine performance and reliability?

The BDFHYK coils aim to reduce misfires and ensure consistent ignition timing by providing a stable high-voltage output and corrosion-resistant housing. Using original-style chips helps maintain proper firing characteristics, while durable polymer materials lengthen service life under heat and vibration.

• Original-compatible control chip for steady spark delivery
• High-temperature PBT and PPO housings resist cracking and corrosion
• Designed to cut misfires, hard starts and uneven idling when properly matched to spark plugs

What OEM part numbers and replacements does this set cover?

This ignition coil set cross-references several OEM numbers to help you confirm a correct match. Check your vehicle’s existing part numbers against the list or consult a parts database to ensure compatibility.

• Common references: UF349, UF349T, CUF349, C1406
• Additional OE matches: 5C1793, 224488J11C, GN10242 and IC479 among others
• Full compatibility list included in product details — confirm against your current coil pack number

How simple is installation and what should I check before fitting?

Installation is straightforward for anyone comfortable with basic engine work: remove the old coils, inspect spark plugs and connectors, then install the new units. Proper torque and clean electrical connections are essential; worn spark plugs or damaged wiring will undermine coil performance.

• Direct-replacement design for bolt-on fit and factory harness connection
• Inspect and replace spark plugs if they show wear or improper gap
• Ensure ignition coil boots and wiring are clean and securely fastened
