I bought an ACDelco PF52 and the equivelant Wix 51036. Comparing them side by side they appear to be identical. Exact same length, same canister style.Both have a red ADBV and have the number "18" stamped on the baseplate.Both have 6 identical size holes in the baseplate. On top of the AC is the number 01130602.On the Wix is 04180602.On the side of the gasket both have identical green and yellow paint stripes. Could Wix be making ACDelco's now?
