Oil filters

[Schralper]

ok so i'd seen the thing about the porsche? filter that fits.
why?

i've been running wix 51334, the EG33 filter.
the other one is wix 51287, which i recently put on.
it doesn't seem like there's much benefit, except like double the $.
in which case i'd rather change the filter twice.
i'm also running a flitermag, http://store.summitracing.com/egnsearch.asp?N=400551+314160+115&autoview=sku
on both engine and ext. trans (wix 51068) filters.

If you're talking about the Porsche 944 filter, the benefits are:

larger surface area = 1. better cooling 2. more filtration 3. increases your oil capacity

it's not going to add 10HP or anything like that, but if u can make your motor work more efficiently why not do it? The OEM filter is clearly way too small for the 3.3L boxer engine on our cars.

BTW, I use STP brand oil filters and it's the same price for the Porsche 944 and the SVX OEM filter, like $6 from auto zone. I've cut one open and they're probably just as good as Wix, they're definitely better than Fram.

i didn't expect any hp but as for the rest :lol:
You are kidding right?

better cooling?
no way. get an oil cooler
more filtration?
maybe a lil more surface area. change the filter more often.
increased oil capacity?
by 6 oz. for what?
i have a hard time believing the svx is so borderline oil sensitive
if i wanted more oil cap i'd get an oil accumulator as insurance.

I haven't measured the 2 side by side, but i'd bet the wix versions i've got here are about the same total area.
these aren't like my different sized chevy ones (wix 51794/51060) where you gain 1qt more capacity in the filter. they're literally twice as big.

Schralper, sorry if my explanation wasn't good enough for you. Everything I said was true, and if you have a better reason for using a larger filter, I'd love to hear it. Or, if you don't see the need for using a larger filter, and would rather use the OEM size filter that's fine too. :-)

[Schralper]

no worries,
i understand the reasoning behind it.
i use the biggest filter i can on my built chebbies.
i just measured the 2
oe wix- 3"x3.25"dia
wix for 944- 5"x3"
my price wix for 944 is exactly twice versus wix#51344
$11.80 vs 5.90
i realize $6 diff ain't that much compared to gas.
i'm gonna compare and see if the oil stays any cleaner in the same mileage.
it's cleaner than before i started using the filtermag.
btw- i'm using 0w30 synth

A bigger filter might be beneficial as it does not get clogged that fast. On the other hand: You might reduce the efficiency as it depends on the pressure applied.
As the line presure does not change but the effective surface of the filter is increased, a bigger filter might work less efficient than a small one.

Don't think the slower speed that the oil passes through the area of the filter is a negative condition. If it actually comes through the surface at a slower rate, if anything at all counts, it could be only positive. The pressure to all the engine components will be exactly the same.

My 2c worth.

Take care,
Keith

P.S. I went right out and checked out the taller filters and am going to give it a try. I am thinking that any difference may not be noticeable?

[Schralper]

the wix 51287 (944 style) has 22% more vol. than the wix 51334 oe style.
580cc vs 472cc
i'm having a hard time see any true benefit from an extra 3.4 oz/100cc of oil filtration. since there's 5 qts. and if i want more cooling i'll add a real oil cooler.
i guess i'll just be changing my 51334 filter more often, even if the belly pan is a hassle.
i'd rather change the filter 2x as often (based on my cost for filter), since it's the filter and not the oil that goes bad first.
especially if you're using a synth oil.

[kwren]

you are probably correct!

Can't afford to save $4.17:lol:

A real porsche filter is about 12 dollars

This is nutz!

Keith

[Schralper]

i suppose this is another option instead of purolator but it's still an $11 filter.

The link you gave shows the price as $6.96??

Enter another zip code, maybe your local store has them entered wrong??

[NikFu S.]

I'm showing 24.99.

[Hocrest]

I've heard that if you go into an Advance and let them know that one of their other stores has it cheaper, they'll give you that price???

My zip code is 17929 if anyone in the $24.99 area wants to check it out...

Don't have a local store listed on the web site for Washington state. Web order is 24.99 and probably + shipping:(

I already got the porsche one the day the information came out on the form and put it on. Fits great!
Keith

[kwren]

And... the oil is super clean!!

(could be due to the fact that I just changed it too?):lol:

Just thought I would give it a try and watch the results.

bigger capacity filter leaves it half way between lo and full on the dipstick for mine.

Now That is weird!!!!
I would like to buy a bunch of those at the 6.95 price but 24.99 is out of the question.

:confused::confused::confused:

I checked it out and ran an order for 11 filters @ 6.96 ea, with your zip code and it took the order!!!

I guess I just joined the tall oil filter crowd!:lol:

So far so good. give it a couple of days to get mine shipped before anyone else tries it please!!!

(kidding about waiting... not about the order... they took it!)
Thank you Hocrest!!!!
Keith:)

[kwren]

They were shipped today!!!!!

I am so excited. no shipping and no tax!

I could have lived with a little shipping, but I hate TAX.

(about time for another tee party...)

oops, that would be golf... (well that also)

This is an invitation for everyone to share in my excitement! Do anything you want to do and while you do it, "Have a great week end"

Got to run... here come the folks in the white coats.

Keith:o

[CorSVXette]

I also used Daves zip code. Got the same same price but had to pay tax. How did you get away with the tax?

[bheinen74]

does the tall porsche one stick down too far.

[Freeman]

does the tall porsche one stick down too far.

Lol! No.. It's not a foot long or anything.. It's like a whole other one of the OEM ones.. It's the only thing I've ever used on mine.

[liamrh]

the wix 51287 or whatevs works great and doesn't hit everything on the road.

[ensteele]

does the tall porsche one stick down too far.

Just don't go over big bumps, or it may knock it off the engine. :lol: :lol: :lol:

It is still above the engine shroud and it is not a problem. :)

[bheinen74]

good just ordered 2 from rockauto, 9.81 each filter

shipping is outrageous, but i ordered several hundred dollars in parts, including a distributor for the Brat since its distributor went into the rescued 83 GL wagon. a clutch kit for the Brat, oil filters for the legacy, and Brat, and GL wagon, pan gasket, etc etc etc

I have a question about the filters, hopefully someone may know.

My common practice when changing oil is to fill the new filter with oil as much as possible, so the filter itself is "primed" upon startup. The OEM Subaru filters and the Purolator OEM-size filters allow this - put the Porsche filter does not.

This indicates a difference in construction - and what the difference is I don't know. I like the concept of a larger filter, just have my doubts as to why it doesn't allow "pre-filling".

Any thoughts on that? :confused:

You could disconnect the ignitor before you actually start the engine.
This allows the bearings to get pre-oiled before you add the pressure of a running engine.
I always do this after the oil pump gets replaced or resealed.;)

[liamrh]

I would assume that it is because it has a better anti-drain back valve.
