Protect your Volvo Penta D4 or D6 with this Osculati 17.501.23 by pass oil filter. Engineered as a direct replacement for Volvo Penta part numbers 3582733 and 22030852 (superseding 21632901), it is the dedicated bypass / secondary oil filter used on the full range of D4 and D6 marine diesel engines.
Working alongside the main full flow oil filter (typically 3582732 / 22030848), the bypass filter routes a portion of the oil through a finer media to remove very small particles, soot and sludge that a conventional filter may not catch. This helps keep the oil cleaner for longer, supporting the long service intervals and high load capability that D4 and D6 engines are known for.
The Osculati canister matches Volvo Penta dimensions, with a 94 mm body diameter and 202 mm height, ensuring correct sealing and flow characteristics in D4 and D6 lubrication systems. It is suitable for all Volvo Penta D4 and D6 inboard diesels and IPS installations where the handbook specifies 3582733 or 22030852 as the bypass oil filter.
Use this filter during routine servicing together with the primary oil filter to maintain optimum engine protection, or keep one as an onboard spare in your D4 / D6 service kit.
