Protecting your engine from contaminants is essential. More precise engineering leaves less room between machine components than before, so choosing the correct filter is more important than ever.

Cat Advanced High-Efficiency Engine Oil Filters have increased contamination control without giving up capacity. They meet stricter emission requirements and are available as an upgrade for some Standard Efficiency Filters when better filtration is favorable.

The Cat 1R-1808 filter contains an improved, higher efficiency filter media. This media is designed to increase contaminant capturing efficiency while maintaining excellent dirt holding capacity characteristics.

FEATURES:

Spiral roving and beading for pleat stability to better trap and hold particles
Properly cured filter media for long performance and life
One-piece aluminum base plate
One-piece molded urethane end caps to eliminate leaks

Caterpillar manufactures over 80 percent of its liquid filter volume on an automated assembly line. This strict quality control eliminates variation from part to part.

The CAT 1R-1808 filter offers better filtration efficiency than standard oil filters, improved engine cleanliness, and longer component life.
