🔧 Engineered Specially for the K15B Platform
The naturally aspirated 1.5L K15B engine is renowned for its durability, but often lacks the power needed when running larger off-road tires, heavy steel bumpers, or roof racks.
The VT Supercharger system utilizes a high-efficiency displacement blower equipped with an integrated bypass valve. This unique setup ensures smooth, linear power delivery without lag, while maintaining factory-like fuel efficiency during low-load everyday driving.
