1. Securely set your car firmly on jack stands, please take precautionary measures and ensure your safety when working under your car.
Caution: For your own safety, do NOT go under an unsecured car supported only by car jack(s)!!!
2. Position the side diffuser into the desired fitment; mark all mounting holes (5 on each side) for drilling in the next step.
3. Drill the previously marked locations with a 7/64" drill bit. It is a good idea to "mark" the drilling points with a center punch to prevent drill bit from "walking."
4. Mount the side diffuser using included screws and washers. Loosely screw in all 5 screws first before tightening will allow easier final adjustments.
