4 - Denso 410cc Modified Acura RDX injectors
4 - Injector jumper connectors
All seals and O rings included.
Currently OEM Honda S2000 injectors produce a maximum of 360cc spray volume. It has been known for some time now the Acura RDX utilizes a K23A1 turbo motor which requires the use of higher rate volume injectors. Therefore Honda/Acura made available a 410cc injector with a relatively inexpensive price tag. Unfortunately for the Honda S2000 2000-2005 model injectors use a unique fitment, 48mm long, 11mm top, and a custom cushion bottom. This makes a direct fit replacement not possible with the standard factory Acura RDX injector. Ballade Sports has custom modified the RDX injector to now become a direct fit into the 00-05 S2000 fuel rail with no added modifications or aftermarket fuel rail. Due to the unique connectors to the RDX injector the use of injector jumpers are required for this conversion. Ballade Sports S2000 410cc injector upgrade allow for more efficient spray pattern and higher duty cycle, thus increasing horsepower while tuning.
OEM Injector Facts:
2000-2005 S2000 Injectors use 360cc Ball Type Injector
2006-2009 S2000 Injectors use 360cc Disc Type Injector
2007-2012 Acura RDX Injectors use 410cc Disc Type Injector
Ball Type Injector - Controls fuel flow by raising the ball off its seat. This allows fuel to flow through the seat orifice and then out through a fixed director plate with several holes. The director plate serves to direct the fuel spray pattern. This type of injector has a 10 to 15 degree angle spray pattern. The fuel adomization of this type of injector is similar to the disc type injector.
Disc Type Injector - Controls fuel flow by lifting a disc off of its seat. The disc has as many as six holes around its circumference. When the injector is activated, the disc is raised and fuel flows through the holes and exits out the orifice. The disc in this injector may actually rotate while the injector is operating. This type of injector has a 10 to 20 degree angle spray pattern. This narrow spray pattern can aid in targeting the fuel.
