Cold-Air-Intake Systems For S197 Mustangs - 5.0 Tech Inspection

Due to the mass air's new position immediately in front of the throttle body, the sensor's wiring harness must be lengthened. WMS provides the wire that is necessary for this task, and Saul uses solder to ensure the connections are solid and permanent.

Western's ram-air box assembles quickly (a flat surface is required), as it only involves securing two borders (included) to the backside edges of the kit's ABS plastic tray. Each border is held in place with two-sided adhesive, as well as small screws. Once assembled, the ram-air box is placed in the radiator cover's original positioned and secured with factory fasteners.

On the left is the new 80mm, billet WMS mass-air housing and the factory's tube is next to it. The physical difference between the two (shape/diameter) is obvious. However it's important to note that overall, the WMS high-velocity intake is not larger than the stock system. According to engineers at Western, with the two setups being so similar in size, air/fuel ratios do not become leaner with the High Velocity and ram-air pieces, so tuning is moreso an option than a must-do task (a DiabloSport calibration for the system we tested can be purchased separately). The stock sensor is transferred into the new mass-air housing using the supplied T-20 Tork screws; the original PCV air tube snaps into a billet adapter that sits in the tube-to-throttle-body urethane coupler.
