Standard UF503T Ignition Coil

Ignition Coil for GM and Suzuki Applications

The Standard UF503T ignition coil is a coil-on-plug replacement built for direct ignition systems that need stable high-voltage output and consistent spark delivery. It is used across a wide range of Chevrolet, Pontiac, and Suzuki applications, including Chevrolet Aveo, Chevrolet Spark, and Suzuki Forenza models.

• Female connector with 1 connector and 3 male terminals
• 12-volt ignition coil for direct ignition systems
• Neodymium core for strong magnetic field and high-voltage output across engine speeds
• Vacuum-injected high dielectric epoxy helps reduce air pockets and moisture intrusion
• Reinforced bobbins help resist voltage flashover for extended service life
• OE-style ignition coil replacement for select Chevrolet Aveo, Chevrolet Spark, Pontiac Wave, and Suzuki Swift+ vehicles

Detailed Product Information

Standard UF503T is engineered as a coil-on-plug ignition coil for vehicles that rely on direct ignition performance. The internal core design supports strong magnetic field generation, while the epoxy-filled case helps protect the coil from thermal breakdown and moisture-related failure. This makes it a practical replacement for drivers servicing ignition systems on Chevrolet Aveo, Chevrolet Spark, Pontiac G3, and related platforms.

This part cross-references Delphi GN10230 and NGK 48932 for the same application. Standard UF503T is also referenced by Standard Ignition UF-503.

Common Problems This Part Can Address

• Engine misfire caused by weak or inconsistent spark output
• Hard starting related to ignition coil failure
• Rough idle from degraded coil performance
• Loss of power under acceleration due to spark breakdown
• Check engine light concerns tied to ignition system faults
