Using this Perrin oil filter cover is simple. First, follow the included installation guide to install it on your vehicle's oil filter. Make sure to align it properly for a secure fit. When it's time to remove the oil filter for maintenance, the knurled grip section on the cover makes it easy to unscrew. As for maintenance, keep it clean by wiping it with a soft cloth. If it's powder - coated or anodized, avoid using abrasive cleaners that could damage the finish. Remember, this cover won't work with aftermarket oil cooler kits, so don't try to install it if you have such a kit on your vehicle.
