Quick delivery.

Quick delivery, now I just need the video on how to replace. Also on the short ones do I use two?

Wrench issue

The lugs that engage the filter housing are symmetrical relative to the handle. This limits wrench travel in restricted spaces. Other filter wrenches skew the lugs so the wrench can be flipped over to gain more travel in tight spaces.

Sizing is wrong suppose to be 41/2 inches and it is actually 6 inch
