Air Jet DGV, DFV, ICT, EPC 130

OVERVIEW

When it comes to extracting every ounce of performance and efficiency from your air-cooled Volkswagen, the devil is truly in the details. The EMPI Air Jet for DGV, DFV, ICT, and EPC carburetors is a critical component for any serious tuner looking to dial in their air-fuel ratio with surgical precision. Unlike generic components, these EMPI jets are engineered to provide consistent flow rates, ensuring that your engine doesn''t suffer from lean-out conditions at high RPMs or sluggishness during throttle transitions. Whether you are running a classic Weber ICT dual-carb setup on a street-driven Beetle or a progressive DGV on a daily-driver Bus, having the right air jet size is the difference between a motor that ''just runs'' and one that screams with reliability. By controlling the amount of air that bleeds into the main circuit, this 130-sized jet helps emulsify the fuel, creating a finer mist that burns more completely and provides a smoother power delivery across the entire rev range.

Achieving the perfect tune requires more than just adjusting your idle mixture screws; it demands a comprehensive approach to your carburetor''s internal calibration. This specific 130 air jet is a staple for those utilizing EMPI EPC or Weber-style ICT and DGV series carburetors, providing the necessary air-bleed correction to prevent the main circuit from becoming over-rich as airspeed increases through the venturi. In the world of air-cooled VWs, where cooling is largely dependent on the proper fuel mixture, an incorrectly sized air jet can lead to excessive cylinder head temperatures and premature engine wear. These precision-machined brass jets are designed to withstand the harsh environment of a hot engine bay while maintaining their tolerances over years of service. If you have been struggling with a top-end stumble or are trying to optimize your fuel economy for long-distance cruising, swapping to the correct EMPI air jet is an essential step in your performance journey.

PRO TIPS

Understand the Air-to-Fuel Relationship

Always remember that air jets have the opposite effect of main fuel jets. While a larger main jet makes the mixture richer, a larger air jet (like moving from a 120 to a 130) will actually make the mixture leaner, specifically at higher RPMs. If your engine feels like it is "choking" or blowing black smoke at wide-open throttle, stepping up to a larger air jet can help lean out that top-end curve. Conversely, if you experience a high-speed surge or "lean pop," you may need to go smaller. Tuning the air jet is the final step in perfecting your main circuit after you have selected the correct main jet.

Never Clean Jets with Metal Wire

One of the most common mistakes in VW maintenance is trying to clear a clogged jet with a piece of safety wire or a needle. These jets are machined to incredibly tight tolerances, and even a tiny scratch from a steel wire can change the flow characteristics of the brass orifice. If your air jet
