Accessport: It has a larger, full - color, high - resolution screen, a customizable multi - gauge display, an in - vehicle mount with an on/off switch, and is faster and easier to use.
Intake: The composite intake body rejects heat, has an integrated velocity stack and airflow straighteners. The 4 - ply steel - reinforced silicone post - MAF in Cobb Blue makes induction and engine sounds more audible.
Air Box: Made of 16 - gauge aluminum, it uses the factory snorkel to feed cold air. It offers the benefits of a CAI without water ingestion issues and has an OEM - quality fit and finish.
Injectors: With a nominal flow rate of 1065cc/min @ 43.5psi, matched sets with less than 1% dynamic flow rate variance, a 14mm bottom O - ring, and data for tuning with Accesstuner Software.
Fuel Rail Lines: Stainless braided PTFE lines, up to 2500psi operating pressure, double - swivel - 6 AN hose ends, SAE 30R9 certified, and plug - and - play with the COBB Fuel Rail Kit.
Fuel Pressure Regulator: An OEM Subaru regulator, plug - and - play with COBB Fuel Rails and Lines, ethanol - compatible, and has abrasion - resistant sheathing.
Fuel Rails: CNC machined from 6061 billet aluminum, black anodized with a laser - etched COBB logo, pre - installed - 8 AN to - 6 AN fittings, compatible with Injector Dynamics Fuel Injectors, and allow parallel fuel delivery.
Turbo Inlet: 6 - ply silicone in stealth black, larger diameter for increased air flow to the turbo, increases horsepower, reduces turbo spool time, improves throttle response and acceleration, and is a direct OEM replacement for 2.4 - inch inlet turbochargers.
Throttle Body Coupler: 4 - ply silicone in stealth black, pad - printed COBB logo, lined worm - drive clamps, a drop - in replacement, and works with stock or aftermarket top - mount intercoolers.
NexGen Flex Fuel Ethanol Sensor Kit: Plug - and - play, includes an ethanol content sensor, mounting bracket, fuel lines, a NexGen Flex Fuel module, and a wiring harness. A billet adapter allows seamless integration with the COBB Fuel Rail Line Kit. The Flex Fuel Module on the passenger - side strut tower processes data before sending ethanol content to the ECU for the Accessport - delivered NexGen Flex Fuel calibration.
Fuel Pressure Sensor Kit (5 Pin): Plug - and - play, enables users to monitor fuel pressure on a custom Accessport, alerts users to fuel system faults, and uses OEM - quality connectors.
