xBoost ignition reliability with BDFHYK Iridium Spark Plugs
Meet the BDFHYK Iridium Spark Plugs (OE 41-114 / 12622441 ILTR5E11). Designed for modern V8 engines found in popular GM vehicles, these plugs combine precision engineering with durable materials to support crisp starts and smooth running under a variety of driving conditions. The result is a plug you can install with confidence, while keeping maintenance needs in check.
Crafted from iridium, the plugs are engineered for fast ignition and consistent power while resisting fouling and wear. A copper core helps transfer heat away from the tip, assisting in stable temperatures and steady combustion across RPM ranges. The insulator is made with isostatically pressed ceramic for strong insulation and reliable performance even in high-heat environments.
Key benefits you may notice
- Faster ignition and quicker throttle response with confident starts
- Potential for improved fuel efficiency through cleaner combustion
- Strong power delivery across highway and city driving
- Reduced fouling risk and longer service intervals (design life up to 40,000–60,000 km)
- Durable construction that resists dirt and wear in demanding conditions
