Cap-style oil filter wrench
This cap-style oil filter wrench fits filter housings with a 73 mm inner diameter and 15 flutes. It uses a 13 mm square drive for standard ratchet or breaker-bar attachment. The metal body measures 83 mm outer diameter and 45.5 mm total height. It is a dedicated hand tool for automotive oil changes.
Upgrading from strap or claw wrenches
Strap and claw wrenches can slip on tight or crushed filters, while this cap design engages every flute for positive grip. The jump is worth it when the filter housing matches the 73 mm size and 15-flute pattern exactly. It removes the guesswork of adjustable tools on stubborn, recessed housings.
Limited to matching filter housings
The wrench only works on housings with a 73 mm inner diameter, 15 flutes and enough clearance for the 83 mm outer diameter. It cannot fit smaller, larger or differently fluted caps, nor can it reach housings blocked by surrounding components. A different cap size or style is required for any other filter housing.

Questions about this item
What drive size does the 73 mm cap wrench need to fit a ratchet?
It uses a 13 mm square drive, so a 1/2 inch ratchet or breaker bar will engage it directly.
How do you install the 15-flute cap onto the filter housing without rounding it?
Seat the 15 flutes fully over the housing flats, keep the wrench square to the filter, and turn counter-clockwise with steady force — the step most people miss is ensuring full flute engagement before applying torque.
When should the metal cap wrench be replaced if the 73 mm inner diameter wears?
Replace it once the 15 flutes show visible rounding or the 73 mm bore no longer grips the housing tightly, as a loose fit will slip and damage the filter cap.
