1.
Carefully remove the dirty filter.
Remnant dust and dirt inside the filter housing will mean contamination of your new filter element before its had a chance to do its job.

2. Always clean the inside the housing.
Dirt left in the housing can lead to engine wear. Use a clean cloth to wipe the inside surface clean and then a visual check to ensure its clean.
|
3. Always clean the gasket sealing surfaces.
One of the most common causes of contamination is improper cleaning of sealing surfaces. Thoroughly clean both the bottom & top of the air clean housing.
|
4. Check for uneven dirt patterns.
Old filters leave valuable clues to dust leakage or gasket problems. A pattern on the filter clean side is a sign that the old filter was not firmly sealed or that dust leak exists.

5. Test your new gasket.
Push down with your finger on your new gasket to test its compressibility. It should spring back when you remove your finger. A high quality gasket is a crucial component of a filter's workings.

6. All gaskets need to must sit evenly.
Re-check that the sealing surface is totally clean. Check that the gasket is the right type for your model. Incorrect fitting gaskets will lead to leakage and contamination.

7. Ensure air-tight fit on all ducts and connections.
Check that all clamps, flange joints aswell as air cleaning mounting bolts are tight and secure there by leading to better filtration.
