How do the outer and inner elements differ and why are both included?

The kit contains an outer element that serves as the primary barrier and an inner element that provides a secondary filtration stage. Together they capture larger debris and finer dust, helping maintain clearer airflow and protecting the carburetor area.

• Outer filter stops larger particles and provides structural support
• Inner filter captures finer dust that passes the outer element
• Both elements installed together restore designed airflow and sealing

What are the physical dimensions and fit details?

The filters are sized to match the original specifications so they seat correctly in the airbox and align with mounting holes. Measure your existing filters or air housing if uncertain to ensure the same dimensions.

• Outer filter: height 10 3/4", width 4 1/8", center hole diameter 2 1/2"
• Inner filter: height 10 5/16", width 2 13/32"
• Form and gasket designed to match OEM sealing surfaces for a snug fit

What maintenance benefits can I expect from replacing these filters?

Replacing both elements as a matched set helps reduce dirt ingestion and maintain consistent airflow, which supports smoother engine operation. While filters don't change engine power by themselves, clean air delivery reduces wear on internal components over time.

• Reduces dirt, dust and debris reaching the carburetor and intake
• Helps sustain designed airflow and engine performance between services
• Easy to replace during routine tune-ups or seasonal maintenance
