Iridium Spark Plug RC12PEC5 Engine Ignition Powerful 3034

This iridium spark plug RC12PEC5 (part number 3034) precisely fits a wide range of GM-based engines from 2.0L to 3.6L including Buick Regal, Chevrolet Cruze, and Cadillac CTS among others from 2000-2010. Core function is to provide strong, stable ignition energy, optimize combustion efficiency, reduce carbon buildup, and ensure smooth engine operation. Though not bearing an OEM number, this model is compatible with GM factory standards. For B2B buyers, cross-check thread size (M14x1.25) and reach (26.5 mm) before bulk purchase to avoid installation errors. Replacement difficulty is medium; torque wrench should be used to tighten to factory spec. As a universal replacement for standard maintenance, reduces aftersales inventory costs.
