The Perfect Tool - Life is Short So Just Buy It.
Size: 88mm x 15
So. Life is too short to struggle with little demons and other inconveniences. I change oil in all my cars, trucks, and SUVs. One of my cars is a V6 Hyundai and the filter cartridge is inside a housing that is sometimes more than a tad inconvenient to loosen and screw back in place. My regular filter removal tools including strap style as well as a three arm gripper type just did not perform very well. I saw this thing, ordered it, and man...it is perfect. The metal top allows a wrench ( spanner) or a socket wrench to be used. I have a fancy Snapon torque wrench which I can also use just to be fancy. In any case removing and re-securing the filter housing on the Hyundai V6 is now a breeze. The cap wrench itself is solid and very well constructed Five stars and count me in as impressed. Well done CTA Tools !!!

Good fit and easy filter removal
Size: 88.5mm x 16
Purchased this for my 2022 Volvo XC60 PHEV. Used up all my 'free' dealer oil changes and not ready to drop hundreds on a simple operation. Removal of the oil filter housing on this car would be nearly impossible without this tool due to its location. With it the process was simple. On a side note, the dealership 'pros' stripped every one of the plastic splash guard nuts. Obviously in a hurry with a power tool. They also did not change out the smaller o ring included with the filter. It's a pain to remove and mine was hardened and likely original. Anyway, placed this tool in drawer with the rest of my oil wrench collection.
