Genuine Caterpillar OEM Oil Filter – 1R1808 (Cross Ref: B7299, 275-2604)

The Caterpillar 1R-1808 Engine Oil Filter is a genuine Cat Advanced Efficiency spin-on lube filter engineered for demanding heavy-duty engine applications.

Its filtration media is designed to capture and retain harmful particles that can contribute to component wear. Caterpillar incorporates a spiral roving and beading design to help maintain pleat stability, along with a one-piece aluminum base plate and molded urethane end caps designed to help minimize leakage.

The 1R-1808 uses a durable one-piece can design and non-metallic center tube to support reliable filtration performance and engine cleanliness.

Choose genuine Cat filtration components when proper fit, filtration performance, and equipment protection matter.
