Powerbuilt Self-Adjusting Oil Filter Pliers offer a safer, faster, and cleaner way to remove oil filters. The secret? They automatically close to the right size to grip and turn filters from 2 1/ inches to 4 3/4 inches diameter. That covers just about every size oil filter on the shelf at your auto parts store. You only need one hand to use them, and the more you turn them the harder they bite. They're constructed from laminated steel for maximum strength and stiffness. And the cushioned handles offer comfort and grip to spare.
