Using this vacuum pump cover kit is easy. First, gather all the parts in the kit, which includes the cover and three stainless socket head cap screws. Then, follow the steps in the install video to attach the cover to your Subaru WRX's FA20DIT motor. When handling the caps, don't worry about the minimal external defects as they won't impact how the product works. For maintenance, simply clean the cover with a soft cloth and mild cleaner. Avoid using abrasive materials that could scratch the aluminum surface. Keep it in a dry place when not in use to prevent corrosion.
