Yeh , I'm pretty sure the larger Wix Xp or the Royal Purple filter will fit , here's pics of my current RP10-48 , plenty of room for a taller filter , but limited to about 3/4 " for a larger diameter filter .
The steering unit is no where near being an issue ?

In case anyone was wondering (as I was) what the sensor was in the second pic, it is the oil temp sensor.

With 2015 non 4x4 have about two inches clearance between electric steering unit housing and bottom of filter housing with short stock oil filter.
Longer filter will be difficult to install with wrench cup
Maybe 4x4 had more clearance than 2x4

The reason I even started considering a diff filter than the RP 10-48 I'm running now is because a member here suggested it may causes higher oil pressure with reduced flow because it has fewer holes for flow , and suggested using the Wix filter with 8 holes for improved flow . This seemed plausible so I purchased the WIX-XP to experiment by recording oil pressures at spacific settings with my current filter with 6 holes and then install the Wix with 8 holes and compare the #s .

I'll be installing the Wix Xp filter tonight and should post the comparison #s tomorrow after work , this will allow me to drive enough on the oil to get it above 200° for good comparison #s .



The holes are not the only variable though so experiment is flawed. The media and design differ enough that holes cannot be one and only factor.

I'm aware of the shorter filter and the electric sterring unit , but there appears to be plenty of room on my 2014 Ram 1500 4x4 for the larger filter . The larger filter is taller but mainly larger in diameter I think .
Wish I had a picture to reference with the RP 10-48 & Rp20-820 side by side .

I wonder as far as the engine is concerned does it matter which filter is used , or if it's just a clearance issue ?



TO ALL , who is using either of these filters

In a 2013 + Ram 5.7L 1500 4x4 with electronic power sterring ?
Thanks for your response !
If you look up the wixxp for the 2013 up ram compared to the2012 wox xp filter as i did you will see the larger filter flows 9-11 lbs and has a pressure relief set at 16 where the smaller wixxp for 2013 up flows 10-12 lbs and is set at 12 lb so just because it will fit it may not be the best choice to use it on a newer ram

That brings up a good point that just because one brand cross references over from another brand, does not mean the bypass pressure relief settings are the same. I have seen 10-15 PSI difference from make to make on oil filters.

I'm going to derail this thrilling filter debate.

Anyone tried a aux oil cooler on a 13+?

Well , I've installed the Wix Xp ( small one ) P/N 57060XP
☆☆☆☆☆☆☆☆EDIT☆☆☆☆☆☆☆☆
For those who haven't read the last couple pages , I have approx 700 miles on my current fill of oil and this is an oil pressure experiment between the Wix Xp and the RP 10-48 Filter on the same oil , @ the same operating parameters. Only difference is the oil filter .
Hope this helps someone ! It's just arbitrary information , but information non the less .




fe4d140b64fde75cec0de6fb98dc1ccf.jpg

I filled it full of oil prior to the install.

Started up & immediately had oil pressure as normal , no tick or abnormal noises.
Went on a 20 mile test drive and my oil pressures with oil temps up to normal operating range of 200+°f my pressures was exactly the same as the RP10-48 Filter ....As expected .
My oil temp at the filter swap was 149° , so tomorrow morning I'll see if my high idle on a cold start differs from before . I highly doubt it .

Anyway , here's some pics of how I always change my filters .... enjoy .

And I never spill a single drop .
Simply break the tq of the filter by hand then lay down rags ( just in case ) and cover with a comparable container , now spin the filter off & let it fall .

Now some comparison photos of the RP10-48 & the Wix Xp 57060XP

Last photo is the Wix Xp installed .

As RodRam eluded to above the holes in the Wix Xp are a tiny bit larger and there's 8ea as opposed to 6 very very slightly smaller holes in the RP filter , which so far has made Zero diff in oil psig .
Also as mentioned above a diff in oil pressures certinly should not be the result of a filter change , unless it's partially clogged . Oil pressure is directly related to the oil being squeezed through internal engin passes and components such as bearings and lifter orifice holes and such , not the oil filter .

With that said I'd like to remind everyone my current fill of RL 40 wt 3ea , +RL 30WT 4ea is reflecting very similar #s of when I ran 5W-20 pyb ...

Thanks to all who've responded and I hope my oil weight and filter experiment has been informative

My thoughts are , if you tow , haul or race a LOT , this may be a good idea .
Or climb a 6+% grade in California heat with 500+lbs of payload for miles at a time multiple times a week raven3 maybe not a bad idea ....

For me , I tow and haul occasionally , but I'm struggle to get my oil to 212° so it's not for me .
Sounds like I'm doing it!

The holes are not the only variable though so experiment is flawed. The media and design differ enough that holes cannot be one and only factor.

The only experiment was that my truck had a faint lifter clatter on cold starts when i started using the RP 10-48 over the fram ultra i had used so i started looking into the difference in the top tier filters. And found the RP had 6 small flow holes where Wix had 8 somewhat larger and the fram had 10! However looking at the video i posted of all these cut apart the frams media was not wraped 100% in pleats it had a flat section which i did not cars for and like the RP it had a stamped steel bypass spring the Wix had the better Coil spring design so imo they are better built but that's my feelings. Once i changed to the WixXp my cold start lifter noise was gone and i had a little better oil pressure hot and cold. So in my real world test it proved better for my application. Now this does not mean the RP or fram are bad only that for me the Wix works better, now the RP might be a better filter for super long OCI but im not a believer that is in the best interest of my motors health. Imo 6-7 k is more that long enough to run any oil. Oil gets contaminated and its a proven fact new oil is better than old oil so i plan on 6-7k oci while using Amsoil even though they say it good for much longer. And im confident the Wix xp will filter just fine for that many miles too.

My thoughts are why do you want another oil cooler? You do know the Rams have a built in oil cooler in the radiator and also oil needs to reach 212 minimum to 230 which is the normal operating temps, i have only seen 228 so far and that was running 80 on the interstate. It needs these temps to burn off condensation in the oil. Now if you are heavy towing and your oil temps are exceeding 230 most of the time then the cooler you linked would probily be a good addition check out jegs performance too they sell quality coolers as well.

Where is the built in Oil cooler? I have yet to find it. I see the transmission lines.

It is a coolant-to-oil heat exchanger style, built in the oil filter adapter.

@ Nutshell , my oil was warm 149° when I installed the Wix Xp filter , I'll have cold oil start #s at high idle in the morning Sir .

It's important for me to note , I've never had any 1rst / cold start ticks or rumble or any abnormal noises .

Flawed , maybe . There are many variables .
For me it really just wasn't about the Qty of holes alone , my test was ultimately filter to filter , regardless of any one individual diff experimenting for since the results was ZERO difference between the two filters then all differences between the two filters are pretty much +-0.

For me the experiment was complete enough , for I wanted to know if the Wix Xp would have any pressure drop over the RP 10-48 on my current oil fill under the same conditions & parameters , and the final results (less a cold oil start up ) was Zero differences .

☆☆☆☆☆☆☆EDIT☆☆☆☆☆☆☆☆

As promised cold start / first start of the day oil pressure with the Wix Xp .

OAT = 61°f
Max high idle rpm = 1450 approx.
Max indicated oil psig=58

Continued pressures on my way to work , I started recording the pressures once the oil Temp was @ 200°f , max oil temp once I got to work 206°f.

55 mph flat ground = 52 psig
65 mph flat ground = 55 psig
75 mph slight + grade = 57 psig
Idle in park 206°f oil temp = 43 psig

These #s are essentially identical to the RP10-48 Filter as expected .

These #s are within 1-3 psig of when I ran the PYB 20 wt oil as well .
With the 20 wt PYB the cold start high rpm idle would be 61 psig at times ? Other times 58-59 psig , the rest of the #s with the 20 wt PYB wer just a tick lower on pressure 1 - 3 psig , thus indicating a bit more flow

So in conclusion as far as the Filter comparison goes Zero differences.

As far as the oil wt goes ( based off temps and pressures ONLY )

Not enough of a difference in flow to convince me to lessen the added film strength I'm getting using a heavier wt oil than the recommended 20wt .
My oil 3ea RL 40wt , 4 ea RL 30 wt which computes to approximately a 33wt oil (if you believe in a sliding scale ) maybe maybe not ?

I also feel it's important to note my MDS works the same with 20wt & my 33wt oil .
I've had Zero issues , my engine is stock less an occ and drop in air filter .
Some seem to be concerned with mpgs , I've notice no change at all , but logic tells me a 20 wt should get a little better ...
I drive like a blue haired grandma most of the time I avg year round about 19 mpg , right now with higher outside air temps my last two tanks I'm averaging about 21.0 .

I hope my experiences with my personal experiment has been informative and helps others make a more informed decision for their spacific wants and needs for oil & filter in truck .

We all operate in diff environments and we all have diff needs , remember it seems diff Rams 5.7L seem to be different as well .

Good luck with your truck !

Like I noted several times over the last many pages the Wix xp was better in my application because it got rid of my cold start lifter noise in RLK's case he has always said he has no noise so I can see where he might not get a since of the filter being better. However what some here that run thick mixtures and trust me redline is very thick compared with other oils in the same grade do not factor in is bypass pressure, if your oil is so thick that the filter can not process it thru the filter the bypass opens and the oil flows around the media not thru it. Not saying this is happening in his case but it is a possibility in any truck running a much thicker oil. At least running the wix you are getting better flow so that's a good thing.
