IDF MAIN JETS

Precision Calibration for Maximum Output Finding the "sweet spot" in your fuel mixture is essential for both power and engine longevity. Our selection of main jets is designed for the tuner who demands accuracy:

• Broad Range of Sizes: We stock an extensive variety of jet sizes, allowing you to move in small increments to find the exact fuel volume required for your engine’s displacement and compression ratio.

• Dual-Carb Consistency: When running dual Weber IDFs or EMPI HPMXs, consistency between all four barrels is vital. Our main jets are manufactured to strict tolerances to ensure balanced fuel delivery across the entire engine.

• Essential for Performance Builds: For stroker engines, high-lift cams, and ported heads, the factory jetting is rarely enough. Upgrading your main jets allows your engine to safely reach its full horsepower potential without the risk of overheating from a lean mixture.

Engineered for Reliability A properly jetted main circuit does more than just add speed; it helps manage cylinder head temperatures by ensuring the combustion process is efficient. Whether you are prepping a Beetle for a cross-country rally or a Sand Rail for a weekend in the dunes, high-quality brass main jets provide the reliable, consistent fuel flow that air-cooled engines depend on.
