Standard 3418-1 Direct Ignition Coil Boot

Direct Ignition Coil Boot for OE Replacement

Standard 3418-1 is a direct ignition coil boot built for OE replacement service on select Cadillac, Chevrolet, Buick, and GMC applications. It uses a straight boot configuration with a black silicone insulator and a multiple-piece design that combines a phenolic tube with a silicone tip for reliable coil-to-plug connection.

With an integrated spring and 2k ohm resistor, this ignition coil boot supports consistent spark transfer in vehicles such as the Chevrolet Camaro, Cadillac CTS, and GMC Acadia. Standard 3418-1 is a direct-fit service part for ignition hardware repair where the original boot has worn, cracked, or lost resistance control.

Detailed Description

Standard 3418-1 is engineered as a direct ignition coil boot for vehicles that use a boot-and-resistor style ignition connection. The straight design, silicone insulation, and phenolic tube construction support secure fitment at the coil end while helping maintain electrical continuity through the integrated spring and resistor. This part number is commonly used in ignition service on Cadillac CT5, Cadillac XT5, Chevrolet Blazer, and Chevrolet Colorado applications, along with other listed GM platforms.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Replacing a cracked or heat-damaged ignition coil boot
• Restoring spark transfer through the coil-to-plug connection
• Addressing misfire concerns tied to worn boot insulation
• Replacing a boot with degraded resistor performance
• Servicing ignition hardware on GM vehicles with OE-style boot design

Installation Notes and Tips

Verify the boot configuration, length, and resistor specification before installation. Standard 3418-1 is listed as an OE replacement part and should be matched to the original ignition hardware layout on the vehicle. Confirm application details for the specific engine and ignition setup on Cadillac CT6, Buick LaCrosse, or GMC Canyon models before service.

Quality Assurance

Standard supplies this ignition boot as a standard-grade OE replacement part built to match the listed fitment and construction requirements for the application.
