This COBB performance package is a must - have for 2008 - 2014 Subaru STI owners. If you already own a COBB Stage 1 Power Package, upgrading to this NexGen Stage 2+ Flex Fuel Power Package is a great choice. It offers excellent value for money. The package maintains legal emissions standards while delivering similar performance and excitement, especially after the removal of downpipes. The package includes a range of high - quality components: an SF Intake System with a black silicone hose, an SF Airbox, a Silicone Turbo Inlet V2, a Throttle Body Coupler, Spark Plugs, Top Feed 1050x Fuel Injectors, an AEM 340LPH High Flow Fuel Pump compatible with E85, a Fuel Pressure Regulator for the Fuel Rail Kit, a Fuel Rail Line Kit, Fuel Rails, a NexGen Flex Fuel Ethanol Sensor Kit, a Fuel Pressure Sensor Kit (5 Pin), and a COBB Vehicle Badge. The NexGen Flex Fuel Ethanol Sensor Kit comes with a module, a plug - and - play wiring harness, an ethanol content sensor with a bracket, and an installation guide. The injectors work well with the stock fuel rail and have a nominal flow rate of 1065cc/min at 43.5psi. The fuel rail lines are made of stainless - braided PTFE, can handle up to 2500psi operating pressure, and are plug - and - play with the COBB Fuel Rail Kit. The fuel pressure regulator is an OEM Subaru part, ethanol - compatible, and comes with abrasion - resistant sheathing. The fuel rails are CNC - machined from 6061 billet aluminum with a black anodized finish and a laser - etched COBB logo. The turbo inlet is made of 6 - ply silicone in stealth black, which increases air flow to the turbo, boosts horsepower, and improves throttle response. The throttle body coupler is a 4 - ply silicone piece with a pad - printed COBB logo and lined worm - drive clamps. The fuel pressure sensor kit (5 Pin) has OEM - quality connectors and is required for COBB NexGen Flex Fuel OTS Maps. The spark plugs have a laser - welded iridium - tipped center electrode and a heat range of 7. The AEM High Flow Fuel Pump is compact and compatible with a variety of fuels including ethanol up to E100, methanol up to M100, and all types of gasoline.
Using this COBB performance package is straightforward. First, gather all the components in the package and make sure you have the necessary tools. Start by installing the SF Intake System with the black silicone hose and the SF Airbox. Then, move on to the turbo inlet and throttle body coupler. These parts are direct replacements for the OEM ones, so they should fit easily. Next, install the fuel - related components such as the fuel injectors, fuel pump, fuel pressure regulator, fuel rail lines, and fuel rails. Make sure to follow the installation guides provided with each component. For the NexGen Flex Fuel Ethanol Sensor Kit, connect the wiring harness and install the sensor with the bracket. Remember, tuning is required for some components like the turbo inlet, fuel pressure regulator, and the Flex Fuel Ethanol Sensor Kit. When it comes to maintenance, regularly check the silicone hoses for any signs of wear or damage. Inspect the fuel components for leaks. Replace the spark plugs as recommended by the manufacturer. Also, keep the air filter in the intake system clean to ensure optimal performance. And always refer to the official COBB website or customer support if you have any questions or encounter issues during installation or use.
