This is a genuine OEM (Original Equipment Manufacturer) Ford part. The part number is BR3Z-6500-A, and it's an engine camshaft follower, also commonly called a valve lifter or tappet. It's a crucial component in the valvetrain of certain Ford engines. If you're experiencing engine noise (like tapping or clicking), loss of power, or misfires, a worn cam follower could be the cause. This is the real deal from Ford, not an aftermarket part, so it's made to the exact specifications and quality standards for your vehicle. Essential for DIY mechanics or professional shops performing engine repairs or maintenance on compatible Ford models. Always verify that this specific part number matches the one you're replacing before purchasing.
