BSLA150P1019 DLC Diesel Injection Nozzle Set

The Fratelli Bosio BSLA150P1019 DLC (SPRINT 1019 DLC) injection nozzles are designed for significant performance and efficiency gains in specific VW TDI engines. These nozzles feature a unique DLC (Diamond Like Carbon) coating on the needle, which drastically reduces friction. This lower friction allows for a higher speed of needle movement, tighter manufacturing tolerances, and less fuel leakage, resulting in more fuel being precisely injected into the cylinder. These benefits translate to higher performance, an extended nozzle lifespan, and optimal operation, particularly when using fuels with a higher percentage of bio-components. The DLC coating ensures smoother operation and greater durability compared to standard nozzles. Installation of these nozzles is specified for engines including the VW T4 2.5 TDI R5 110kW/151hp (code AXG). For other VW Group engines like 1Z, AHU, AGR, AFN, AVG, expect performance increases to approximately 122 hp, while ALH and ASV engines may reach around 124 hp. These figures are based on simple installation and may require supporting modifications for higher outputs. The product is also noted as comparable in flow to the SPRINT 764. DBW LLC also offers these nozzles as part of a comprehensive package that includes injector body cleaning, overhaul, mounting, balancing, re-coating, and return lines. They also offer a HotSwap™ program for a convenient exchange. The nozzles are ULSD rated and come with a 5-year unlimited mileage warranty when installed correctly. Variable staged flow settings (Stages I-V) are available to fine-tune performance from 120-190hp and beyond, depending on supporting modifications. It is important to confirm the connector type on your vehicle, as 2002.5 models may use older connector types.
