Tomei Powered: Japanese Engineering Without Compromise

Tomei Powered USA Inc. carries a reputation that resonates through pit lanes, dyno rooms, and weekend track days around the world. Founded in October 2006 and headquartered in Lake Forest, California, the company operates as the North American arm of Axesta Inc., whose engineering and manufacturing base is rooted in Zama, Kanagawa Prefecture, Japan. All product development and manufacturing oversight for the Tomei brand flows directly from that Japanese headquarters, ensuring every part meets the exacting standards the brand is known for.

The story behind Tomei is one driven by a refusal to compromise. Axesta Inc. was founded in 2014 by Akira Sasaki — a former top executive of Tomei Powered Japan — alongside engineers who shared his vision of building world-class tuning parts free from the restrictions that governed the domestic Japanese market. That founding philosophy, captured in the brand's identity as "The Engine Specialist," has since produced a catalog of components that are trusted not just by street-car enthusiasts, but by professional racing teams and tuners on multiple continents.

Tomei's product range is notably broad for a brand so focused on quality over quantity. The lineup spans engine internals — including crankshafts, connecting rods, camshafts, valve train components, and head gaskets — as well as turbochargers, intake components, fueling hardware, and drivetrain parts. Where Tomei arguably attracts the most attention, however, is in its exhaust systems. The flagship Expreme Ti cat-back exhausts are crafted from full titanium, delivering meaningful weight savings alongside the aggressive, race-bred sound character that JDM performance enthusiasts have come to expect from the brand. Stainless steel manifolds and downpipes round out an exhaust lineup designed to optimize flow from the head all the way to the tip.

Beyond the engine bay and exhaust tunnel, Tomei also brings the same precision-first approach to the driver's most tactile connection with the car. The brand's Duracon shift knobs — machined for a direct, adapter-free thread fit — have been a favorite among enthusiasts for decades, offering a warm, naturally grippy feel that improves with every mile. Available in multiple height profiles to suit different driving positions and seating setups, they are a small but meaningful upgrade for any manual transmission car.

Tomei's platform coverage is a major part of its appeal. Whether the application is a Nissan RB26, Subaru EJ or FA-series engine, Mitsubishi 4B11T, or Toyota 2JZ, Tomei engineers have developed purpose-built components tested under real competition conditions. In 2023, Axesta Inc. opened a newly built headquarters facility in Zama City, equipped with precision machining equipment, a roller dyno, and a purpose-built logistics warehouse — a clear signal that the brand's commitment to development and quality control is only deepening.

For performance builders who take the details seriously, Tomei represents something increasingly rare: a brand where race-proven heritage and uncompromising engineering standards drive every product decision.
