K-Jet .108

The KINSLER K-Jet .108 is a precision-engineered brass component designed for builders and tuners working with carburetor fuel metering systems on performance engines. This critical jet controls fuel delivery into the main circuit of Kinsler carburetors, making it essential for anyone tuning forced-induction motors, naturally aspirated strokers, or high-RPM competition engines.

The .108 orifice size sits in the mid-range of the Kinsler jet lineup, offering a balanced fuel flow rate for engines requiring moderate to aggressive fuel enrichment without running excessively rich at cruise. Manufactured from brass for durability and corrosion resistance, the K-Jet .108 features a precisely drilled orifice that meters fuel with tight tolerances—critical for consistent air-fuel ratios across the RPM band.

Carburetor tuners, drag racers, circle-track competitors, and street rodders building custom fuel systems rely on Kinsler jets to achieve repeatable performance and drivability. Installation involves simply swapping the jet into the carburetor's main metering position, allowing tuners to dial in the exact fuel curve needed without replacing the entire carb body.
