Secondary Engine Air Filter for Caterpillar | Part 130-4679

Maintain your machine’s peak performance with the Caterpillar Secondary Engine Air Filter (Part No. 130-4679). This element is the critical "last line of defense" for your engine, designed to protect the intake while the primary filter is being serviced or in the unlikely event of a main filter failure.

Engineered with a radial seal for a secure, airtight fit, this standard efficiency filter ensures that dust and debris never reach the internal mechanisms of your iron. It is specifically optimized for use in CAT 3056, C6.6, and C7.1 series engines found in industrial generators, wheel excavators, and agricultural equipment.
