K-Jet .108

The KINSLER K-Jet .108 main pill is a precision-engineered brass component designed for high-performance carburetor tuning and fuel system optimization. This 0.108-inch inner diameter metering pill serves as a critical flow-control element in mechanical fuel injection and carburetor systems where precise fuel delivery directly impacts engine performance, throttle response, and overall driveability across varying load conditions and RPM ranges.

Manufactured from brass, the K-Jet .108 pill delivers consistent metering characteristics essential for carburetor calibration. The 0.108-inch orifice diameter is a standard specification within KINSLER's established product line, allowing builders and tuners to match fuel delivery rates to engine displacement, boost levels, and intended operating parameters. Individual metering pills enable fine-tuned adjustments without requiring complete carburetor replacement, making this component indispensable for street and competition applications where fuel mixture optimization is non-negotiable.

Carburetor and fuel injection tuners, engine builders, and performance shops rely on KINSLER metering pills to dial in proper air-fuel ratios during dyno testing and field calibration. Whether adjusting a carbureted domestic engine, fine-tuning a vintage hot rod, or establishing baseline fuel metering on a freshly built powerplant, having the correct main pill size ensures repeatable combustion efficiency and predictable part-throttle behavior. The K-Jet .108 is sold individually, allowing you to source exact quantities needed for your specific tuning work or inventory management.
