Description
The Feuling 9948 fuel injectors deliver reliable fuel flow for Harley-Davidson® engines that need a strong OE-style upgrade. This matched pair flows 5.1 grams per second and installs easily using an EV-1 Minitimer plug-in connector.
Because these injectors use a 4-hole nozzle with a 20-degree dual spray pattern, they improve fuel atomization and throttle response. As a result, engines run smoother and respond quicker under load.
These injectors work best in stock to mild/medium performance VRSC, XL (Sportster), and Twin Cam engines. They support combinations with mild head work or increased compression. Therefore, Feuling recommends them for builds making 95+ rear-wheel horsepower.
Additionally, the Feuling 9948 replaces factory IWP063/B injectors and Harley-Davidson® OEM #27665-01/A, making it a true OE replacement with proven performance.
