I have off and on used the Supertch ST2 filters on my F-150 5.4 Those and Motorcraft. Bought a few Mobil 1 AC Delco and Castrol Maxpro when K-Mart had them on sale. I found some of the Supertech filters at Wally World with the bypass spring in the top like Ford says it should be. You guys think these are okay?? I bough all of those they had cause they are hard to find. Are these an older style they are discontinuing or are they a newer version to come up to Ford specs? Really have to look through all the boxes to find them though. They seem to have a lot more of the one that are made like the STP/Bosch filters than the ones that are made with the bypass spring in the top(next to the mounting base).
Metroplex, The filters I have are the black ones that are supposed to be patially synthetic. Think they are okay?? Did they change lately to cut costs maybe?
