Description

The Acura RDX fuel injector (Part # 16450-RWC-A01) is a genuine OEM Denso component designed as an upgrade for Honda engines. It offers a 410cc flow rate at 38 psi and 550cc at 70 psi, providing significantly more fuel flow and better atomization compared to the factory Type-S injectors (310cc). These injectors are an excellent choice for both stock and modified naturally aspirated K-series engines, especially those with performance enhancements like cams, upgraded valvetrain, or intake manifolds that may be pushing the limits of the stock injectors. For 9th Gen Civic and 1st Gen ILX customers, specific plug-and-play pigtail clips are available to facilitate installation. Please note that advanced engine management tuning is essential to properly control these higher-flowing injectors. Additionally, a "Prop 65 Warning" is in effect, indicating the product can expose you to chemicals known to the State of California to cause cancer or reproductive harm. This product is not legal for sale or use in California on any emission-controlled motor vehicle.
