Grams Performance is a USA-based sister brand to Skunk2 Racing, focused on precision-engineered drive-by-wire (DBW) throttle bodies and high-flow fuel system upgrades. Their DBW throttle bodies are machined from billet aluminum to exacting OEM+ tolerances, delivering sharper throttle response and maximized airflow for both street and track applications.

Complementing the throttle bodies, Grams’ fuel system lineup includes uprated injector kits and supporting hardware—each injector calibrated for consistent spray patterns and higher flow rates to suit boosted or naturally aspirated builds. Every component is designed and tested domestically, ensuring direct-fit installation, exceptional durability, and the confident performance enthusiasts demand.
