Changing Air Filter

Share |

September 13, 2012

Briggs & Stratton engines use one of three types of filters: Paper, Foam, and Dual Element Air Filter including a filter cartridge and pre-cleaner to ensure your engine will run smoothly this season and the next.

We also offer special high performance air filters designed to extend the life of your outdoor power equipment. These filters last twice as long as our regular filters and allows your engine to perform at the highest possible level.  

Paper Air FilterPaper Filter
A paper air filter element works by causing any air that is intended to enter the combustion chamber of the engine to pass through a filtering device made with microscopic holes in it. The paper element traps the dirt particles on the outside of the element. How to change a paper air filter.

Foam Air FilterFoam Filter

The “foam only” style air filter system works by trapping dirt and debris through the use of motor oil spread throughout the oil foam holding medium. A dry or non-oiled oil foam filter will trap only the largest particles. If the air filter element is foam only, it MUST be oiled and serviced regularly. How to change a foam air filter.

Dual Element Air Dual Filter
Combination filters provide the highest degree of air filtering in the industry. The foam portion is used as a pre-cleaner for the paper element. Pre-cleaning the air increases the life of the more expensive paper element. Air passes through 2 types of filtering mediums providing clean air for the engine.
