Show original supplier description
The COBB Tuning Subaru 08+ STI Fuel Pressure Regulator Kit provides a straightforward, plug-and-play installation for your vehicle. Designed to eliminate the common 2800 rpm stumble experienced in 2008+ Subaru STI models, this kit ensures a smoother driving experience. It requires no modification of factory hoses, making installation simple and easy. This kit features an OEM Subaru Fuel Regulator and Dorman Quick Connect Fuel Fittings, along with sheathing for abrasion resistance. It is flex-fuel compatible, offering versatility for different fuel types. The kit includes the fuel pressure regulator manifold reference relocation kit. Attention: Custom tuning is required for this kit to function correctly. COBB recommends consulting their dealer network to find a Protuner for your specific setup. While this part is undergoing external testing for emissions compliance, it is not currently legal for sale or use in California on any emission-controlled motor vehicle.
