I have noticed on many online aircooled parts stores that they sell an aftermarket oil pump adapter with spin on oil filter for most of the type 1 engines. I've been told that these work well as an upgrade as opposed to the original filtering system which most of the time leaves way too much debris and gunk circulating in the engine unless you change the oil every 2000 miles. Do any of you guys have any comments on your experience with these filtering systems?  I have included some photos of a Gene Berg System for Type III's and a link to a similar system.  Many thanks folks for the advice.

I don't have any experiance with external filter/coolers, but speaking from what I've heard from everyone else over the years -- If it comes from Gene Berg and your wallet can stand the hit, it's probably a good system.  If it says EMPI or it's made in China, India or Brazil, I'd recommend sticking to regular oil changes.   :wink:

I'm gonna second that, Chris.  The empi stuff is kinda poo, and just about guaranteed to leak.  The stock system works, but Gene Berg is da man when it comes to add-on legitimate improvements.  like Zen said, if your wallet can stand it....

I have used the CB unit and was happy with it.  The only thing that I have run into is SOME not all of these pump/filter units cannot be used with the stock exhaust system. Some are even tight on space when used with headers. The Berg system is fine if you want to put up with the hassle of running hoses and mounting the filter somewhere plus the high price.

Well that leaves one more question.  Where and how would you mount the filter itself?

There is a c shaped wierd clamp that mounts on the 3/4 side of the head the oil filter attaches to. off the top of my head JayCee makes one. I think they call it a claw???
