Premium Iridium Spark Plug for Enhanced Engine Performance

High-quality iridium center electrode ensures superior ignitability and fuel efficiency, delivering consistent power output. Platinum side electrode minimizes wear, extending plug lifespan up to 60% longer than standard copper plugs.

Precision-engineered heat range (41-122) prevents pre-ignition, optimized for high-temperature performance in turbocharged engines. Laser-welded construction eliminates misfires, maintaining stable combustion under extreme conditions.

Direct-fit replacement for Chevrolet Cruze, Sonic, and Cadillac models (OE# 55585534). Seamless compatibility with OEM engine management systems, no ECU recalibration required.

Ideal for city commuting, highway cruising, and performance tuning. Reduces cold-start hesitation and improves throttle response in stop-and-go traffic.

Factory-sealed packaging with anti-corrosion coating. Each plug undergoes 12-point quality inspection including gap measurement and pressure testing. Sold in bulk quantities at wholesale pricing for repair shops and fleet managers.
