1970-1979 Oil Strainer Screen Dual Relief Case 1600cc 111115175B - OEM Number(s) (111-115-175-B)
Protect Your Engine the Classic VW Way
Our Oil Strainer Screen filters out metal flakes, sludge, and foreign particles before they can circulate through your Air-Cooled VW’s oil system. This direct-fit screen is designed for dual relief engine cases and features a 19mm (0.75") internal diameter on the oil pickup horn. A crucial component in early VW lubrication, this mesh screen ensures clean oil delivery and extends engine life.
Why Your Drain Plate Might Not Have a Plug
In 1971, Volkswagen deleted the drain plug from many factory oil plates. Mechanics were skipping proper oil strainer cleaning, causing warranty issues. Instead of pulling the plate to service the mesh screen, they were simply draining and refilling—neglecting the debris trapped at the base. VW's solution? No more plug—forcing full plate removal at each change.
If your plate lacks a plug and you want the convenience back, we offer several upgrades:
• Standard Plate with Plug – Part 353026
• Billet Aluminum with Plug – Part 300200 or 319908
Tech Note: Identifying Your Case Type
Look underneath your engine. If you see two nickel-sized slotted caps (one near the flywheel, one near the oil pump), you have a dual relief case. If there’s only one, you have a single relief case and should use a different strainer.
