What Not To Use: Bosch, STP, and Wal-Mart Supertech
While both the STP and the Bosch filters were at one point good filters, they are now manufactured off shore of sub-standard parts. The filter assemblies tended not to have even pleats and generally less media than other comparable filters. There was also a complete lack of a well functioning by-pass valve. With most filters there is an obvious and discrete by-pass valve, but with these filters the can spring and the by-pass valve are the same. The real issue is that in order for the filter to properly by-pass the entire filter assembly would have to move down during use. That is actually not possible with filter assembly properly seating into the anti-drain back valve. This means that the by-pass will effectively never work. In the center of the of picture below you see the filter assembly (top) and the can spring/by-pass valve (bottom). (The can spring / by-pass valve would flip over and into the filter assembly.)

Not all of the wal-mart supertech filters are chinese. I just bought one, #ST3675 and it says product of usa on the filter. On the box altough, it says check filter for country of origin.

You may want to note that Bosch Premium filters are of at least decent quality and made in the USA (mine was anyway).

Doesn't Bosch have less filter media (total square inches) compaired to Purolator oil filters ??

I read here somewhere that Champion inports 20% of their filters. Or something like that.

I've been stocking up on the Valucraft ones @ A-Zone. All are Pre-Ecore and say "product of USA" right on them.

Good stuff

I stay away from Frams amd Pennzoil since they are Frams and Purolaters with the bypass valve on the wrong end.

I was going to go back to useing Baldwin filters but I called my distributor and they want $6 a filter and that is not for an HPG filter either!!!! I will not buy a filter that cost more then $4.25!!! Their is no spin-on full flow filter for a gasser worth more then $4.25 in my book! I had thought about going back to SuperTech until they went to that stupid Encore design!!!

So now I am going to look for Hastings or Puralator at a decent price!

Al wmy walmarts still stock the pre-Ecore 3950 Made in the USA supertech. I have a couple left for the Outlander. Never fear, bad reviews are a dime a dozen..I kind of wish that theymade a 3950 Ecore, but as of right now they don't.

I like how panic spreads.
