Questions And Answers Of The Customers

Is the KW1638 a primary or secondary (safety) air filter element?

The KW1638 is a primary high-efficiency air filter element. It is designed to capture the vast majority of airborne contaminants before they reach the engine. In many heavy-duty housing designs, it is used in conjunction with a smaller, inner secondary safety element.
How does the KW1638 protect the turbocharger on the 4BTA3.9 and 6BT5.9 engines?

The turbocharger’s compressor wheel rotates at extremely high speeds. Any dust or debris bypassing the KW1638 will act like sandblasting media on the aluminum turbine blades, causing "blade erosion" and loss of boost pressure. A genuine KW1638 ensures optimal protection for the turbo’s lifespan.
Is the KW1638 genuine or an aftermarket replacement?

It is genuine Fleetguard air filter. We also provide high-quality aftermarket replacement https://www.megawattsparts.com/kw1638af1811-fleetguard-air-filter-mw001638-compatible-with-cummins-engine-filter-parts
