K-Jet .058

The KINSLER K-Jet .058 main pill is a precision carburetor jet component designed for high-performance and fuel-injected engine builds, where metering accuracy is crucial for optimal tuning response and throttle control. Engine builders and mechanics depend on these jets to ensure consistent fuel delivery in custom carburetors and electronic fuel management systems.

With a .058-inch orifice size, this jet is positioned in the mid-to-lean range, making it suitable for applications requiring precise fuel control during steady-state cruise and acceleration mapping. Kinsler jets are manufactured with exacting tolerances, featuring a hardened brass construction that minimizes variations that could affect air-fuel ratio consistency across different RPM ranges.

Builders working with carbureted street machines, circle-track race engines, or retrofitted electronic injection systems will find the K-Jet .058 particularly beneficial. Its primary pill design allows for quick swaps during dyno tuning sessions, enabling rapid A/B testing without the need to disassemble the entire fuel system. This versatility makes it an excellent choice for those looking to optimize performance without compromising throttle responsiveness.
