Alcohol Jets (2)

The Holley Alcohol Jets (2) are precision carburetor components engineered for high-performance fuel systems running on methanol or alcohol-based fuels. These jets are essential upgrades for racers, hot rodders, and serious automotive enthusiasts who demand maximum power from naturally aspirated or boosted engines. Alcohol fuels burn cooler and require different jetting ratios than gasoline, making dedicated alcohol jets critical for optimal engine tuning and reliability in competition or high-output street applications.

Constructed from precision-machined brass, the Alcohol Jets feature a 0.156-inch inner diameter (Number 156 specification) that delivers the correct fuel metering for methanol combustion chemistry. Holley's manufacturing tolerances ensure consistent fuel flow across the pair, critical for balanced cylinder fueling and predictable power delivery. The brass material resists corrosion from alcohol's hygroscopic properties while maintaining dimensional accuracy through extended use. Proper jetting directly impacts air-fuel ratio at peak boost or rpm, preventing lean-out conditions that cause detonation and engine damage.

This pair suits Holley carburetors across street, strip, and road-racing platforms where alcohol fuel systems deliver superior octane and cooling benefits. Installation requires basic carburetor tuning knowledge—jets replace stock gasoline jets in the float bowl. Verify your carburetor model and fuel system specifications before ordering, as alcohol jetting differs significantly from gasoline equivalent sizes. Proper installation and carburetor baseline tuning ensure maximum performance and engine longevity in alcohol-fueled applications.
