What Katech does

Katech Engineering LLC is a Clinton Township, Michigan-based performance engineering company founded in 1977 by Fritz Kayl and Warren Frieze. The company specializes in high-performance automotive engine development, precision CNC machining, and motorsports engineering, with a primary focus on GM LS and LT platform engines. Its offerings span Custom Spec Engines, Installed Vehicle Performance Packages (covering C5-C8 Corvettes, Cadillac CTS-V, Gen 5-6 Camaro, and GM trucks/SUVs), and a broad catalog of performance parts including superchargers, throttle bodies, TrackFlow billet dry sump oil pumps, KoolFlow billet thermostats, ignition systems, and cylinder heads. In-house manufacturing capabilities include multi-axis CNC machining for porting services and powder coating for durable finishes.

The company operates a horizontal go-to-market across three primary customer segments: private enthusiasts and aftermarket buyers (served via direct e-commerce at katechengines.com and a dealer network), professional racing teams (notably Trans Am TA2), and OEM/automotive manufacturers (including a long-standing engine development relationship with the GM Corvette Racing program and a newer research partnership with Renault Group for autonomous vehicle testing). Revenue is generated through one-time parts sales, mail-in CNC machining services, professionally installed performance packages, and race car preparation services, with publicly disclosed unit pricing ranging from $9.99 for spark plug insulators to $11,899.99 for the Gen 5 V8 Truck/SUV Stage 1 supercharger package. Katech is a privately held LLC with 11-50 employees and no disclosed institutional ownership.

The firm leverages race-proven engineering discipline from its Corvette Racing involvement as a core differentiator across commercial products. Marketing is multi-channel, combining an e-commerce storefront with fitment guides, an email newsletter, six social media platforms, and a Become-a-Dealer program. A 2026 partnership with Renault Group and Valeo at Renault's Busan, South Korea plant signals an emerging extension of Katech's engineering capabilities into autonomous and remote control vehicle development beyond the traditional motorsports and aftermarket core.
