This Briggs and Stratton OEM lawn mower air filter is designed to work with 3 and 5 horsepower industrial plus and 5.5 horsepower Vanguard engines. An air filter is the first line of defense against dirt and debris that can be kicked up from the mowing process.

The spark plug boot is a rubber piece that is responsible for connecting the spark plug to the spark plug wires and completing the connection. Spark plugs are necessary to create the engine spark that will start the motor in lawn equipment and other small engines. The boot holds the terminal and keeps everything protected from the elements and insulated so that it continues to work correctly. If the spark plug connection seems weak or if the existing boot is damaged, this replacement could provide the solution. This durable rubber boot will insulate the spark plugs and help any small engine run better.

This genuine OEM replacement part is a spark plug terminal for a wide variety of small combustion engines. In a combustion engine, the spark plug generates a small electrical charge that creates enough power to start up the ignition and engage combustion. The plug connects to the ignition through the terminal. Spark plugs generate and then pass a small electrical current through to the ignition. Usually, the main issue with spark plugs is that this current hyper-extends and ends up frying the spark plug. However, if the terminal is damaged, the charge will not pass into the ignitor, and the engine will not turn. If the spark plug can carry a charge but the engine still won't turn, it's likely the terminal that needs replacing. This is an easy repair because the terminal should just snap on and off. If stuck, a pair of needle-nose pliers should make it easier. This high-quality replacement part is compatible with engines from Murray, Toro, Lawn Boy, and Briggs & Stratton. It is sourced from the original manufacturer and ships individually.

This replacement pre-filter is an authentic OEM part for a wide range of small and medium sized gas-powered lawn appliances. Before gasoline passes into an engine's combustion chamber, it is first mixed with air in the carburetor to make a balanced and well-oxygenated fuel. The air comes in from outside of the engine. However, if the air is full of particulate matter, it can sully the fuel and cause the engine to degrade. To prevent this, manufacturers install an air filter to catch dust and debris. This is a pre-filter that adds a second layer of protection for the carburetor. After a few months of regular use, an air filter will usually have reached its maximum capacity. If left for too long, it can block air from entering the carburetor and cause the engine to choke up. Therefore, it's important to replace filters and pre-filters every two to three months. This is an easy fix, as most air filters will just pop open. If not, use a screwdriver to gain access. This replacement pre-filter is designed for Briggs & Stratton and Toro appliances. It comes from the original manufacturer and ships individually.
