1989 GMC P3500 Performance Coils

Hypertech is a technology-driven company with a unique status in the aftermarket industry. Unlike other speed equipment manufacturers that produce hard parts like camshafts and cylinder heads, our core product is knowledge the ability to tune the complex computers that control essential functions in modern automobiles. We have invested in people, not machinery. The knowledge and skill of the Hypertech team are our most valuable assets. Our staff of engineers and technicians has degrees in a variety of disciplines, including electrical engineering, computer science, and mechanical engineering. Hypertech people know computers from the inside out! The Hypertech team is passionate about performance. We have racers, hot rodders, and performance enthusiasts on our staff. You’ll find modified trucks and street machines in our employee parking lot. We build project cars and use our trucks for towing on weekends. We come from different backgrounds, but we have all learned to appreciate the tremendous power of electronic engine controls to improve performance on the street as well as on the race track. Hypertech is the technology leader in High-performance engine tuning computer-controlled vehicles. Electronic engine controls have evolved rapidly since their introduction in the early ’80s. Hypertech has kept pace with these rapid advances in technology by developing power tuning products that take advantage of the capabilities of these electronic controls. Early automotive computers used replaceable PROMs or chips to calibrate the Electronic Control Module (ECM) for a specific engine, powertrain, and vehicle combination. Hypertech created the original Power Chips to recalibrate these electronic brains for improved performance. As the power of digital systems expands, Hypertech will continue to design and manufacture power tuning products that are on the cutting edge of technology.

Product Features:

• External Coil
• Product might not be available in all states due to local laws.

Hypertech’s Power Coil is capable of firing a street or slightly modified engine up to 7000 RPMs. Voltage gain over stock can exceed up to 57% more output depending on application. Stock coils usually average around 36,000 volts as compared to Hypertech’s coil kits that average between 45,000 and 55,000. Our coil kits include coil, brass terminals, cap, and rotor. Nylon rotor hold-down screws are included to prevent misfire, and our caps are made of high dielectric material to prevent carbon tracking. Each cap fits the distributor housing tightly to eliminate leakage. Power Coil/Caps/Rotors are NOT legal for sale/use in CA.
