STi oil filter seems too small. What about a bigger filter and a heat shield?
I've seen the Impreza oil filter go from huge to microscopic in a few years, which sucks. I just realized that the filter for my 05 STi is the same as my wife's 02 Mazda Protégé 5! I have read that the push for a smaller filter on Imprezas was to keep them from being too close to the header (heat transfer to the oil) . So what about going back to the older, bigger filter and making a oil filter heat sheild? Anyone remember what the old Purolator Pure One part number was for the Impreza? Any thoughts?

No need for a larger filter. In fact why would you want a larger filter? The STi filter is the very same as the WRX filter.

Purolator does make a Pure One filter that is the same as their filter for the STi except that it is slightly longer. Dia., sealing surface, thread pitch is all the same as their filter for the STi. I do not remember the exact part number though. However, it is the exact filter specified for my wife's 03 Honda Element. Check out the fitment guide for the Element and you will have the longer filter for the STi. The last time I changed the oil on both cars, I was going to just get two of the longer filter, but they only had one of each in stock. Next time, I'll make sure to get the longer one. HTH

I'm pretty sure there are better things to worry about. That filter is spec'd with (without a doubt) a significant factor of safety. Its probably at least double what is required for the engine. You're engine is only .5 liters bigger than your wives, the block is the same size as a 2.0 wrx Why would you think you need a bigger filter???

You do realize that you are trying to out engineer a team of professional engineers at Subaru who specialize in this sort of stuff right? While you are free to do so, realize that your efforts are really for naught. If you are THAT concerned, get off the wallet and buy a $200 bypass unit that filters your oil to HEPA levels. This will both relocate and outfilter the OEM unit.

Somebody over on IWSTi.com purchased and cut open a large number of the most poplular filters and compared the internals. The consensus was the stock filter was one of the best ones out there in terms of construction and/or filter media area.

the subura filter is a quality filter, my dealer charges $6.50 and it's well worth it. i change w/ M1 oil every 4k, imo if your so concernced about clean oil then why would even consider changing it at 7.5K intervals. |
