Walker Products 920-1009 ThunderSpark Ignition Coil Canister

The Walker Products 920-1009 ThunderSpark Ignition Coil is a canister-style replacement ignition coil engineered to restore reliable spark delivery to your vehicle's ignition system. Acting as a compact electrical transformer, it converts the battery's 12-volt supply into the high-voltage pulse needed to fire the spark plugs and ignite the air-fuel mixture in each cylinder.

Key Features:

• OEM Fit, Form, and Function: Manufactured to meet or exceed original equipment specifications for a direct-fit replacement with no modifications required
• High-Voltage Output: Capable of producing voltage pulses up to 40,000 volts from the vehicle's standard 12-volt electrical system
• Precision-Wound Primary Coil: Low-resistance primary winding allows substantial DC current flow, which is then interrupted to generate a high-voltage spike in the secondary winding
• Step-Up Transformer Design: Secondary coil features a significantly higher number of turns than the primary, maximizing voltage output for consistent, reliable ignition
• Quality Inspected: Every unit is tested before packaging to ensure it meets Walker's strict performance standards
• All-Conditions Capable: Designed for reliable performance in both city and highway driving, as well as on- and off-road applications
• New Construction: Contains no remanufactured components
