GM AC/ Delco Style Super DIS Coil 86+

The ACCEL GM AC/Delco Style Super DIS Coil 86+ (Part Number 140017) is a high-output ignition coil pack designed for General Motors vehicles equipped with Distributorless Ignition Systems from 1986 onward. Built to OEM specifications, this super coil delivers 45,000 volts of spark energy, providing the reliable cold-start capability and consistent firing performance required in modern engine management systems.

The coil features a 0.500-ohm primary resistance rating and male HEI connector interface, ensuring direct compatibility with GM DIS ignition modules and wiring harnesses. The bright yellow housing aids in visual identification during engine maintenance and diagnostics. At just 1.3 lbs, the compact 3.65 x 3.6 x 4.8-inch form factor fits into tight engine compartment spaces without interference with other components, making it an efficient direct replacement for worn or failing original equipment coils.

This ignition coil is ideal for owners maintaining or restoring late-model GM vehicles—trucks, SUVs, and sedans—that rely on DIS technology for precise ignition timing. Whether addressing weak spark output, rough idle, hard starting, or complete coil failure, the ACCEL 140017 delivers the voltage consistency needed to restore proper combustion and engine performance. Mechanics and enthusiasts choose ACCEL coils for their reputation in the aftermarket ignition sector, particularly when OEM parts are unavailable or cost-prohibitive.
