Description If you're looking to upgrade your RHF4, RHF5, RHF55, RHV4 VNT, or some actuated applications, the custom-built td04l frame is the perfect solution for achieving more power from your engine. The Kinugawa td04l turbochargers are known for their exceptional response and overall flow potential, making them ideal for mildly tuned applications. However, these turbochargers may need more efficiency if you require higher boost levels. That's why the turbine and compressor wheel combination is an excellent choice, providing more power throughout the rev range with different varieties and a larger diameter than the factory turbocharger. Choose this upgrade to experience improved performance and power for your vehicle.
