Show original supplier description
The Turbosmart Kompact EM VR25 plumb-back blow-off valve is engineered as a direct, high-performance replacement for the factory diverter valve in the Nissan 400Z. The valve also features a positive seal O-ring on the piston face. This upgrade offers a true plug-and-play solution, allowing for a straightforward installation by simply unplugging and unbolting the OEM valve and installing the Kompact EM in its place, without requiring any adaptors, hoses, or extra assembly. It incorporates an onboard, proprietary solenoid system and internal pressure control channels for seamless integration with the factory ECU, ensuring full OE control without the need for reference hoses or separate solenoids. Constructed from billet aluminum and featuring high-temperature o-rings, the Kompact EM VR25 is built for durability and reliability. The valve is available in both plumb-back and dual-port options to suit different preferences and applications. This product is specifically designed for the 2022+ Nissan 400Z Twin Turbo V6 (RZ34). It is important to note that this product does not have a CARB EO number and is not legal for sale or use in California on pollution-controlled motor vehicles. It is intended as a "Race Only" product for competition use only, and any other use may be a violation of local, state, and federal laws. The buyer is responsible for verifying legal use for their intended application.
