Found this chart of larger bodied filters. They all have 20X1.5 threads. For reference the Fram PH7317 is 3.47" high by 2.69" Wide. When I change my oil this week I will measure clearance and see how big I can go for next time. You can drop first 5 from the Wix# to get the Napa Gold#.

Don't you also need to measure the O-ring diameter so you get a proper seal?

asand1

iTrader: (1)

Yes, that'll be part of the trial fitting. I'll also have to look and see if there are obstructions to the body of the wider filter.

ive looked into this once

i forgot what i found

IIRC there are a couple of longer filters out there for us to use.

i think my end verdict was to get an adapter and use a larger filter and then i gave up?

if you find something lemme know

OK, here's what I found while changing my oil. The gasket surface on the engine measures 72.39mm O.D.. The 1182 Napa filter is 72mm O.D.

The closest obstruction is at the 5 O'clock postition and I measured short at 33mm from the threaded nipple. 33mmX2=66mm+20mm(nipple)=86mm O.D.. The 1182 Filter measures 93 mm O.D.. This means It will be a close fit, if at all. Basically, if I measured 3.5mm short it will fit. I wont try until I Change my oil in 3K, So if anyone wants to try first post your results please.

The 1344 filter should definitely fit.

----------seal OD-----can OD-----can HT
Stock----64mm------65mm------87mm
1344----63mm------82mm------103mm
1182----72mm------93mm------132mm

According to FRAM, 51344 is equal to PH9688 and PH3593A.

Both part numbers with cross reference to other brands.

The cross references seem to lose size, so Ill stick with the Napa gold or Wix.

jus wanted to kno wat difference will it make? larger oil filter? will it be beneficial for the engine?

asand1

iTrader: (1)

The smaller a filter is, the quicker it loses its ability to flow due to captured particles. After it gets to a certain point, the bypass valve allows unfiltered oil into the the engine. I don't like the idea of unfiltered oil pumping through my engine. A larger oil filter also increases the engines oil capacity by a small amount.

A larger oil filter doesn't mean there is more or less filter media inside.
You should be looking at the filter that has the best filtering media, not the size of it.

asand1

iTrader: (1)

Its a real good indication though. A thimble with a very fine media will plug up sooner than a larger one and start bypassing earlier. At that point it really doesn't matter how good the media was.

If you have ever changed oil on a 4cyl before, I wouldnt say our oil filter is small. I always use the K&N 1010 and when I change my oil about every 4500k the oil is still in great shape. It would add piece of mind to have the ability to filter more out though so I am in to see how it fits, thanks.

asand1

iTrader: (1)

Can anyone tell me how thick the Lower oil pan is where that 5 O'clock protrusion is. The
1182 filter is larger and $4 cheaper than the 1344. I would use the die grinder to remove a couple mm.

Quickywd01

iTrader: (16)

This is great but don't forget if you don't use a filter with the correct bypass pressure you will have problems. I also used a larger pureone filter but nothing this big, yet. Don't forget about the function of the bypass.

asand1

iTrader: (1)

Good point, all the more reason to run the 1182, the bypass is 24 where as the original is 13, meaning less bypassed oil into the engine. Racers are known to block the bypass when built into the adapter. Its really only needed in very cold climates or when owners dont change their oil often enough.

Quickywd01

iTrader: (16)

I was worried about cold start up.

njmaxseltd

iTrader: (19)

On a well maintained engine, you shouldn't be worrying about bypassing. You should absolutely be worrying about the micron size and capacity of the filtering media. I can use a screen filter and never go into bypass mode. Wouldn't want to see what the bearings looked like after 10K miles...
A huge filter could have 50 pleats and say 1 foot of paper filter media. The same amount of paper could be fit into the smaller container, just add more pleats and you've got the same surface area. So again, don't assume the larger filter gives you more surface area or any better filtration. It's just not true. It's all about the filter media inside, it's surface area and it's filtration rating (about 25-30 microns).

Look at the oil analysis spread sheet in the fluids section. There's never been any mention on any lab report of excessive contamination due to a lack of filtration.

Use a good detergent oil and any filter that meets the OEM requirements and change them regularly. That's all that's needed to see 300K or more on these engines. Anything else and your really just wasting your hard earned $$$$.

As I read the specs on the 57356 Maxima filter and the 51182 larger size, I noted 3 differences that were in favor of the Maxima recommended one:

By-Pass Valve Setting: 8-11 PSI vs 24 PSI
Max flow rate: 9 - 11 GPM vs 7 - 9 GPM
Burst Pressure: 363 PSI vs 350 PSI

The by-pass pressure is 3 times higher on the larger filter. If the filter ever plugs (which will ideally never happen) you may not have enough oil pressure at idle to operate the by-pass valve.

The maximum flow rate could be an issue. What is the oil flow rate in the engine?

The bursting pressure of the big filter is slightly less which I doubt is even worth considering. But it makes me wonder why.

asand1

iTrader: (1)

Ok the 1344 has the high flow rate as well. I guess the lower bypass pressure will be ok, as the filter media will be larger and the pressure differential should never get that high anyway.
I just don't see any benifits being worth the $11 price tag. Ill see if I can't find a cheaper crossover.

The larger filter will have more square inches
Of surface area inside the can. This means at a given psi, a larger can will have more force applied to its internal walls. Its the same relationship between psi and brake caliper piston size.

The correct napa # for our car is 1365. The Xterra and Frontier call for a 1356 filter which is slightly longer than the 1365 but all other dimensions are identical (including the o-ring). I'm guessing it maybe holds an 1/8th of a quart more if that. I've been using the 1356 filter and putting in a full 5 quarts of oil and the oil level shows just barely above full (on a 2005). Since the car uses a little bit it works out perfect for me.

I was hoping this would work out but seeing how the larger one flows less oil... Can't have that if you're running at 7200 rpm lol.

I'm changing oil this weekend and plan on getting the regular fram filter. Bought a Mobil1 last time and to me it wasn't worth double the price of the fram. I've used fram on my motorcycles and it was fine as well as cars... Anyone got a problem with fram?

asand1

iTrader: (1)

Lots of people don't like the fiber end caps on fram filters. As far as I know they don't actually pose a real threat. My self I will stay away from them just for the fact that you can buy better for less.
As far as the larger filter the 1344/51344 flows the same and has equal filtration. I will order a couple from the website above before my next change.

ABIGBRAIN

iTrader: (1)

Do you honestly think that any oil pump made for a VQ motor is going to be able to fully circulate all 4.5 quarts of oil 8 times in 60 seconds? 9 gallons of flow through the filter per minute is the minimum on the NAPA 1344.

Andy

carsnwomen91

actually till today i though that... oops forgot about that bypass valve

so by reducing the psi for the valve to open (delayed i guess or doesn't even reach opening pressure?) you're forcing oil through the filter possibly reducing the necessary amount of oil getting to the engine (i'm just using my logic so please correct ). a good thing to compare the two would be knowing the pressure of oil at wot to redline

asand1 they have the same nominal micron rating (filtration media class/rating?) but the larger one flows less (7-9gpm vs 9-11).

asand1

iTrader: (1)

The 1344 filter also flows at 9-11 gpm.
The low flow filter (1182) has been scratched from the list already.

asand1

iTrader: (1)

The oil pump and filter are both capable of outflowing the oil passages due to tight tolerances. There is no way 8 GPM flows through all the bearings.

carsnwomen91

Ooo ok my bad I missed that. I'll give it a try this weekend if I can find one at Canadian tire/partsource or Walmart. I would definitely like the added oil volume!

asand1

iTrader: (1)

In doing research I have found that the 1344 filter has been popular with Honda and Subaru guys for years. I guess in the ricer world, sometimes bigger really is better.

ShocknAwe

iTrader: (3)

When are you going to change your oil with the new filter? Do you have a way to test oil pressure as well? I am curious to see if it will work for us as another 1000k miles between oil changes will be nice

I'll be doing mine tomorrow

The oil filter on my 98 Civic with a 1.6 liter 4-banger is bigger than my 3.0 V6 Maxima filter. At least 1 and half times the size.

Then again maybe its a Nissan thing because the 98-2002 Altima with the "big" 2.4 liter 4-banger uses the same oil filter as the 3.0 V6 Maxima.

go figure

Post side by side comparison pics old and new please.
I wont be changing my oil again for while.

iTrader: (3)

Given that most wear to an engine occurs at startup, and that a larger oil filter would mean a longer time for the oil to reach lubricating parts (oil pump has to force more oil through the larger filter).....does the benefit of larger capacity outweigh the potentially detrimental factor of a longer time for oil to flow at startup?

asand1

iTrader: (1)

Because of the anti drain back valve, there is already oil in the filter. If you've ever changed your own oil you can attest to this. As soon as oil is pushed in, pre-existing oil is displaced into the engine oil passages. There is no delay.
