Advanced Efficiency Engine Oil Filter 1R-1808 for Caterpillar Diesel Engines
1R-1808 oil filter for Caterpillar 3406, 3408, 3412, 3306B engines and C9-C15 platforms. OEM cross-reference verified. Orders from IXIN Filter.
Description
This 1R-1808 oil filter is an advanced-efficiency full-flow spin-on engine oil filter engineered as a direct replacement for the Caterpillar 1R-1808, one of the most widely specified lube filters across Cat’s 3300/3400-series industrial engines and C-series diesel platforms. It’s built to capture the fine, damaging particles that standard-efficiency filters can miss.
Product Overview
The 1R-1808 oil filter is engineered with a higher-efficiency filter media designed to increase contaminant-capturing performance while maintaining strong dirt-holding capacity, targeting the fine particles most likely to cause abrasive wear on lubrication system components. It’s built with a one-piece can and a non-metallic center tube for a clean installation and a reliable seal, and can serve as an upgrade path for equipment originally fitted with a standard-efficiency filter. Each unit is manufactured with a 1-1/2-16 UN spin-on thread and dimensionally verified against OEM measurements before shipment.

Frequently Asked Questions
What engines use the 1R-1808 oil filter? It’s used across a wide range of Caterpillar diesel engines, including the 3406, 3408, 3412, and 3306B industrial engine families, as well as the C9 through C18 diesel platforms used in on-highway trucks, off-highway equipment, and generator sets.
Is this a standard or advanced-efficiency filter? The 1R-1808 is an advanced-efficiency filter, offering improved contaminant capture compared to standard-efficiency filters of the same physical size. It’s also used as an upgrade option on equipment originally fitted with a standard-efficiency filter.
Is this the same as the 1R-0716? The 1R-1808 and 1R-0716 share very similar physical dimensions (height and outer diameter), but the 1R-1808 uses advanced-efficiency filter media, while the 1R-0716 is a standard-efficiency filter. Confirm which efficiency rating your engine requires before ordering.
Do you offer samples before a bulk order? Yes. We recommend requesting a sample for independent testing before committing to a bulk order, especially for first-time buyers.
