STREET / STRIP HEI distributors Our HEI distributors are built from the ground up with all new components. We have engineered a special high energy module that operates without misfires beyond 7500 RPM. That's nearly 3000 RPM higher than most stock HEI distributors. Flame-Thrower HEI distributor produce 67% more energy with a 45% faster spark breakdown time when compared to the stock HEI. This means twice the energy to the spark plugs. Our tests show that with these improvements wider plug gaps can be used resulting in an increasing flame kernel growth for more efficient combustion.
Features:
  • Balanced rotor reducing vibration at high RPMs.
  • New lightweight aluminum alloy housing.
  • Legal in all 50 states and Canada (C.A.R.B. E.O. #D-57-23)
  • Aligned and honed high quality bronze sintered bushings for reduced friction and extended life.
  • Meets stringent automobile susceptibility, vibration and shock requirements.
  • Centerless ground corrosion resistant shaft reduces friction and provides concentric operation.
  • Distributor gear is ground to exact tolerances for tighter mesh with camshaft. (Bronze distributor gear available)
  • High dielectric strength cap with brass terminals and low resistance center coil brush.
About Pertronix, Inc

Originally known as Per-Lux, the company was founded in 1962, primarily a manufacturer of driving and fog lights for the heavy-duty truck market. In the early 70's, a Per-Lux engineer developed an electronic ignition system that would replace the points and condenser in distributors. After patenting the product, Per-Lux started manufacturing the Ignitor® with sales and marketing emphasis on the forklift and industrial engine markets. Soon the Ignitor was introduced to the automotive market, offering its superior performance and in 1985 the first replacement electronic distributor was introduced. In 1991, Tom Reh acquired the Ignition Division and PerTronix was born with a total commitment to the ignition market. In the years that followed, the reliable, high quality, competitively priced Ignitor took over the industry with Sales of Over 4 million units to date. The expertise and industry knowledge within PerTronix had the team setting their sights on new product segments and so began the legacy of PerTronix Performance Brands.

With the tremendous growth of the performance industry in the 90's, PerTronix began to shift our emphasis to our automotive product offering. This substantial growth, along with the addition of our Flame-Thrower® coil and spark plug wire product lines made it necessary for PerTronix to expand production and relocate to a brand new 22,000 square foot custom manufacturing facility in 1997. Today, PerTronix is renowned for our Ignitor Series points replacement kits, HEI performance modules, Flame-Thrower HEI, Billet and Cast Distributors, Ignition Coils and Spark Plug Wire sets. Ignitor kit sales have exceeded 4,000,000 units. The release of our Innovative Digital HP Ignition Box represents our continued commitment to lead the Ignition Industry.
