Oil Filters - Quest for the Best, Anyone do testing in the 914 arena? Options

[bandjoey]

I started my own search for oil filters quality last week after an oil change. I have always walked into a parts store and picked up a filter...BUT...Are they all the same?? (IMG:style_emoticons/default/idea.gif)

What started the questioning was a part number on a Bosch filter. On a prior change I always bought from the local Porsche parts shop - they just handed me a Bosch filter 72137, and I put it on. When I started to do this oil change, I was out of filters, so I went to AutoZone. They stock Bosch. The filter book on the shelf showed the 3204 and the 32138 Bosch filters fit the 914 4 - a different number than the Porsche shop filter ?? On the Bosch site their part finder agreed with the Autozone book. So, why did the Porsche shop sell me a different filter number. (the 137 vs the 138 filters looked identical from the outside.

I did a search on World, and went through all 22 pages of oil filter posts. Googling also brought up Corvette, Honda, and other sites with filter posts. It's about a 50-50 tossup for Bosch. People like it and hate it..no real testing could I find. The only consistent opinion is that FRAM is only for lawn mowers. (IMG:style_emoticons/default/biggrin.gif)

This is a web site of oil filter analysis for What's Inside, but no real information on what works best.

Jake - You're the expert on OIL but what about Filters??

OK experts. Chime in. I'm listening. (IMG:style_emoticons/default/popcorn[1].gif)

frams in vangons are bad, more pressure drop and the back flow valve is not present. (hence lots of lifter noise after long sits) the Mann brand does not suffer as such. (personal experience here)

difficult to find, but internet search will get you the specificaition on each filter, pressure drop, back flow vlace, by pass pressure etc... these are importnat parameters. when i added an extenal cooler, I had to use a sandwhich plate, so i had to seek out a smaller filter, many would "fit" but not all had the same pressure drops, and by pass settings, so i had to search and find on that was short enough, and had the same factory specs as the OEM one

look up "Bob the Oil Guy" on the world wide web, sign up and post a question, there are many folks on that site and they can give you great filter info.
