PerTronix Flame-Thrower EST Distributors

Pertronix Flame-Thrower EST performance distributors for GM late model computer-controlled (EST) applications dramatically improve high-rpm performance. When used with their Flame-Thrower remote-mounted coil, voltage to the spark plugs is increased by more than 40 percent. These distributors are a direct bolt-in for most 1987-93 GM cars and 1987-95 trucks. Additional features and specifications include: * Housing is cast and machined from strong but light A384 alloy * Ignition modules are laser-trimmed for precise peak current control and use thick film technology for greater accuracy and improved reliability * High dielectric strength cap and rotor with solid brass terminals to prevent high-rpm arcing * Centerless-ground, corrosion-resistant shaft reduces friction and provides concentric operation * High-quality bronze sintered bushings are installed, aligned, and bored for accuracy and extended mileage use * A hardened steel distributor gear is machined to exact tolerances for a tighter mesh with the cam gear, eliminating horsepower losses caused by timing fluctuations found with excessive clearance and wear * Legal in all 50 states and Canada (CARB E.O. #D-57-13) Show Less
