JET® Performance Products, Inc. was started 45 years ago as an engine building and carburetor store specializing in Drag Racing applications. In 1985 Mike Jones, the company’s founder, sold it to its present owner Bryant Seller. The company, led by Seller, got the name 'JET Performance Products' and launched the first performance chips for General Motors applications. Continuing to be a leader in the tuning industry, JET provides a wide range of performance programmers, modules, chips, throttle bodies, accessories, as well as carburetors.
