Many will-fit manufacturers have filters that will work, but the construction of the filter doesn’t take into consideration actual operating conditions.

Toro designs all filters so you can be confident that they’re manufactured to meet or exceed engine and application requirements. For example, tests show that will-fit air filters can allow up to 10 times more dirt to pass through the filter into the engine than Toro air filters. With genuine Toro filters you get consistent performance over the life of your engine and they help ensure full engine performance and protection in-between services.
