K-Jet .106

The K-Jet .106 is a precision-engineered brass main pill designed for high-performance fuel injection systems in drag racing and engine tuning applications. This component is purpose-built for competitors and engine builders who demand exact metering control in carbureted and nitrous oxide systems. Whether you're running a bracket racing program or building a fuel-injected engine for maximum efficiency, the K-Jet .106 delivers the precision sizing required for consistent, repeatable performance across multiple passes.

Manufactured by Kinsler, a respected name in fuel system engineering, the K-Jet .106 features premium brass construction that resists corrosion and maintains dimensional accuracy under high-pressure operating conditions. The .106-inch specification denotes the precise orifice diameter, critical for controlling fuel flow rates in both naturally aspirated and forced-induction applications. At just 0.01 lbs, this compact main pill integrates seamlessly into most fuel metering blocks without adding unnecessary weight, while the machined tolerances ensure repeatability that translates directly to lap-time consistency and engine reliability.

Racers, engine shops, and serious enthusiasts rely on the K-Jet .106 when tuning carburetors or fine-tuning fuel injector sizing for specific displacement, boost level, and fuel type combinations. Installation is straightforward—the main pill drops into compatible Kinsler fuel blocks and similar metering systems. If you're chasing optimal air-fuel ratios or stepping up power levels, having multiple jet sizes in your pit kit allows quick on-the-fly adjustments without breaking down fuel systems, making this component essential for both track testing and competition day.
