MSD 8223 Blaster 3 Extra-Tall Tower Ignition Coil Oil-Filled Canister 45000V

The MSD 8223 Blaster 3 Ignition Coil is a high-output, oil-filled canister coil engineered for street and performance applications. Delivering up to 45,000 volts — 15,000 more than a typical stock coil — the Blaster 3 is a direct upgrade to your existing coil or an ideal companion to MSD 5, 6, and 7 Series ignition systems.

At the heart of the Blaster 3 is a 100:1 turns ratio winding housed inside MSD's signature red metal canister, filled with premium-grade oil for effective cooling and long-term durability. The lower primary resistance (0.7 ohms) works in combination with the high turns ratio to maximize voltage output and deliver a strong, consistent spark.

Key Features:

• Extra-tall secondary tower — twice the height of a standard coil tower, preventing secondary arcing and ensuring a secure coil wire connection
• 45,000-volt maximum output — significantly outperforms stock coils for improved ignition performance
• Oil-filled red metal canister — premium-grade oil keeps windings cool and protected; must be mounted in a vertical (upright) position
• 100:1 turns ratio with low 0.7-ohm primary resistance for maximum voltage build-up
• Includes 90° HEI-style spark plug terminal and boot for a secure, weather-resistant coil wire connection
• Compatible with electronic ignitions and MSD 5, 6, and 7 Series ignition systems
• Ballast resistor required when used with points-style ignition systems
• CARB E.O. Approved — legal for use on emissions-controlled vehicles in all 50 states

Specifications:

• Maximum Voltage: 45,000 V
• Inductance: 8 mH
• Peak Current: 140 mA
• Spark Duration: 350 µs
• Primary Resistance: 0.700 ohms
