Key Features

• Direct ignition coil boot kit for OE-style replacement

Detailed Product Overview

Standard Ignition CPBK181 is engineered for vehicles that use a direct ignition coil boot assembly rather than a traditional plug wire setup. The phenolic tube and silicone tip help form the connection path between the coil and spark plug, while the included spring and resistor support proper ignition transfer in the boot assembly. This makes CPBK181 a practical OE replacement choice for drivers servicing ignition components on models such as the Chevrolet Malibu, Cadillac CTS, and GMC Canyon.

This part cross-references 99-227K for the same application.

Common Issues This Part Can Address

• Cracked or heat-damaged ignition coil boot components
• Intermittent spark transfer at the coil-to-plug connection
• Misfire concerns related to worn boot materials
• Hard starting caused by degraded ignition boot contact
• Service replacement needs on direct ignition systems

Installation Notes and Tips

Verify the vehicle’s ignition system layout before installation and compare the original boot configuration to the straight design of CPBK181. Inspect the coil, spark plug, and surrounding ignition components for wear or contamination before reassembly. For best results, install on the confirmed application listed for your year, make, and model, including 2013-2018 Cadillac ATS, 2014-2018 Chevrolet Impala, and 2018 Chevrolet Traverse.

Quality Assurance

Standard Ignition supplies OE replacement ignition components for service and repair use. CPBK181 is built to match the original-style fitment and construction expected for direct ignition coil boot service on supported GM applications.
