The spark plug gap is the distance between the plug's center electrode and the ground flap (curved conductor at end of plug). The size of gap determines the arc voltage delivered to the air/fuel mixture resulting in internal combustion. Incorrect gap size may cause your equipment to operate erratically and could also fail to start. GPS Oil Filter Wrench To ensure quality of service, always use the correct tools for the job. With the cup style oil filter wrench included in this kit; preventative maintenance will be a breeze. Perfect for hard to reach & hard to grip filters. You can maintain your equipment like a PRO!
