The Injen SP9003WB is a Wrinkle Black short-ram cold air intake for the 2016-2018 Ford Focus RS 2.3L turbo four-cylinder. This is an SP intake, replacing every component in the OEM system, including the airbox and the intake pipe. The tubing is 6061-T6 aluminum, and the filter is an Injen SuperNano-Web dry air filter that can be serviced rather than replaced as a sealed unit. Where a stock airbox leaves the RS's intake path restricted, this swap is meant to open it up.
The main reason to choose this intake over stock is that it is built to fit the 2016-2018 Ford Focus RS L4-2.3L Turbo, no tune required! Injen's black powder-coated heat shield is designed to keep warm under-hood air away from the filter. Injen's published dyno gains have varied between its own pages, so confirm the current figure with the manufacturer before you buy. Buyers in California and several other states should note that this product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles.
Injen describes this as a direct bolt-on: no cutting or modification to factory components are necessary. All necessary hardware is included for a quick and simple installation. Owners on user forums describe the intake as having a built-in MAF housing, which removes the need to relocate the sensor. Searchers looking for an SP9003WB install, a 2016-2018 Focus RS short ram intake with no tune, or a CARB-status check for a Focus RS MK3 intake should find the key details here.
No. The manufacturer states that this product is not CARB exempt, and it is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles. The manufacturer also lists several other states where it cannot be shipped.
The manufacturer says no tune is required, and the intake is designed to work with the factory tune.
Yes. The manufacturer states the SP intake replaces every component of the OEM system up to the turbo, including the airbox and the intake pipe.
The manufacturer lists it for the 2016-2018 Ford Focus RS L4-2.3L Turbo.
The manufacturer describes this as a direct bolt-on that requires no cutting and includes all necessary hardware, so the job is mainly removing the factory airbox and intake pipe and fitting the new tube, heat shield, and filter. The manufacturer does not publish a tool list or install time in the sources I found, so check the included instructions before you start. Owners on user forums say the MAF sensor sits in a built-in housing on this intake, so check that the sensor connector is seated and the boot is clamped correctly before you test the car.
