The element measures 3-1\/2\" inside diameter by 5-3\/4\" outside diameter. If the filter element on your S3, P3, S4, or P4 pump is dirty, torn, or collapsed, this is the correct OEM replacement. Running a compressor pump without a serviceable inlet filter is a fast way to destroy pump valves and bore surfaces — abrasive particles from unfiltered air cause accelerated wear that no amount of oil changes will compensate for.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eManufacturer page data was not available for this listing.
