Standard Motor Products UC21 Ignition Coil OEM Replacement

The Standard Motor Products UC21 is a direct-fit OEM replacement ignition coil engineered to restore reliable ignition performance. The ignition coil is a critical component of the engine's ignition system, responsible for converting low-voltage battery current into the high-voltage energy needed to fire the spark plugs and ignite the air/fuel mixture in each cylinder.

Key Features:

• OEM Replacement Design – engineered to match the fit, form, and function of the original factory coil
• 100% Pure Copper Windings – used in both the primary and secondary bobbins for improved durability and higher resistance to internal shorts and dielectric breakdown
• Full E-Lam Silicon Steel Core – limits magnetic circuit loss factor to reduce heat buildup and extend coil service life
• Solid Brass High-Voltage Terminal – protects against corrosion and ensures consistent electrical contact
• Enamel Magnet Wire Windings – provide the highest temperature rating available in the aftermarket
• Special Blended Compound Formula – optimizes performance, longevity, and heat dissipation
• Built for Maximum Output Voltage – delivers strong, consistent spark energy across all engine speeds and loads

Standard Motor Products is a Tier 1 manufacturer with over 100 years of experience in ignition components. All ignition coils are produced under strict quality control standards from raw componentry through finished product, ensuring reliable, maintenance-free operation that meets or exceeds OE specifications.
