Premium Iridium Spark Plug for Buick Engines

Ultra-fine 0.6mm iridium center electrode ensures precise ignition and extended durability. Laser-welded construction prevents performance degradation under extreme heat.

Multi-angle ground electrode design optimizes flame propagation for 15% faster combustion efficiency. OE-spec heat range (41-993/41-962) matches factory Buick ECU parameters.

Dual-YAG laser welding creates airtight seal against carbon buildup. Platinum sidewire reduces misfires during cold starts (-30°C).

Direct-fit replacement for Buick LaCrosse/Regal/Enclave models. CNC-machined hex body prevents stripping during installation.

Bulk pricing available for repair shops and fleet operators. Ships in OEM-grade packaging with anti-corrosion coating.
