Reliable Ignition Performance by CHENDAXHUN

CHENDAXHUN was shaped by a tradition of precision engineering and engine service culture, creating dependable ignition parts that honor Nissan's legacy of performance while solving modern daily-driver problems. This UF349 ignition coil pack and spark plugs set is a complete tune-up solution for rough idle, hesitation, engine surging, hard starts, and P0300-P0306 misfire repair. You get 6 high-output ignition coils and 6 double iridium spark plugs—built to restore smooth power and consistent firing.

Precision Fitment for Nissan & Infiniti V6 Engines

The 6-pack ignition coil set replaces OE numbers 22448-8J115, 22448-8J11C, and 22448-8J111, compatible with Nissan and Infiniti 3.5L V6 platforms. This ignition coil pack fits 2002-2004 Altima, 2002-2003 Maxima, 2003-2004 Murano, 2002-2004 Pathfinder, and Infiniti I35, QX4 models. For drivers searching for a reliable coil pack replacement or a complete V6 engine maintenance set, this 12-piece kit brings all the key service parts together in one box. Please verify your vehicle's engine type and OE number before purchase.

Advanced Materials & Design

OE 22448-8J115 style coils use high-dielectric epoxy for superior heat resistance and stable output, helping the V6 engine work perfectly under high-temperature or heavy commuting conditions. The double iridium spark plugs feature a fine-wire center electrode and come pre-gapped for strong, rapid ignition. Our components are engineered for magnetic suppression and cleaner signal delivery, providing reliable combustion for your Altima, Maxima, or Pathfinder.
