The Mac Tools product is a set of oil filter cap cups designed specifically for Toyota and Lexus vehicles with 4-cylinder and 6/8 cylinder engines. These cups are essential tools for changing and installing oil filters in these types of vehicles. The Mac Tools brand is known for producing high-quality automotive hand tools, making this product a reliable choice for car enthusiasts and mechanics looking to maintain or repair their vehicles. The Mac stickers have long since fallen off. I notice these are no longer sold on the website as a set like this.
