I think most from this forum will tell you to stay away from sinister products. I had their coolant filter and I hav the aluminum oil filter cap

 

bypass coolant filters are not a guarantee of debris not landing where it shouldn't but it does eventually filter all the fluid

i think they are good for monitoring whats going on when you cut the can open and separate the pleats

i think bypass oil filtration is a good thing I have a FS2500 and i wouldn't suggest it
I would get a Amsoil setup ( and no I don't preach Amsoil or use their fluids )

 

I have the sinister bypass coolant filter, but I also have a bpd oil cooler.
If I had an oem style oil cooler I'd probably use the IPR coolant filter. It's a full flow filter system.

I also have an amsoil bypass oil filter, using the bpd bracket to mount it. Mounts right up in the front bumper behind the passenger side. Bolts in in about 5min, easy access to change the filter. Great setup.

 

I'm not too concerned with brand, I just liked the looks and location of the Sinister set up. Don't care about color. Not sure what other makes or brands are out there. Guess another question is what's so bad about sinister diesel products. Ultimately I am looking at this as a way to make sure I have well filtered fluids. Plus by watching some of the you tube videos and knowing that when it comes to farm use some times it is impossible to keep things clean.

 

The only thing "bad" I'd say about the sinister coolant filter is that it's a bypass. Meaning it only filters a small amount of fluid all the time. And that goes for any brand that mounts in that location and is a bypass system. They are all the same.
Where as the ipr kit, is a full flow system. It filters 100% of the flow of fluid all the time. Effectively having a much greater impact on the cleanliness of the fluid. BUT, the flip side to that is that it is maintenance dependant. If not monitored and maintained being that it is full flow, if it clogs, 0 coolant flowing through that, or partial floe, creating some issues that you don't want to find out about.
The flip side to the bypass style, if the filter clogs, it clogs. And it just doesn't filter anything, there is no impact on flow of coolant elsewhere to where it needs to be in the engine.
So imo, if you have a bpd oil cooler, go ahead and go with the bypass style, it's less reliant upon filtered and clean coolant, maintenance is simple and less regulated.
If you have an oem style liquid/liquid oil cooler, go with the ipr full flow kit. As your liquid/liquid is 100% reliant on clean filtered coolant in good shape.

 

O.K, I'll say it. Sinister sucks! I have the coolant filter but as soon as I can afford the IPR Full FLow filter I'll be doing away with leaky Sinister crap.

+1 on the IPR coolant filter. Hindsight being 20-20, the bypass filter I bought was a waste of money. Not a bad product, but I now feel a bypass setup isn't the answer. Realistically, the IPR filter isn't full flow either, as it only gets the coolant directed to the heater core; but, it is a much better setup than other bypass kits.

As to Oil bypass filtration, The OEM filter does a very good job filtering as low as 20 microns. As such, any bypass filter that is rated at 10 micron or higher isn't doing much for you. The Amsoil EaBP filters are rated for 2 microns, I have been using them for years.

 

I was just having this discussion today with a guy working on my house. I don't know much about IPR filters. He was saying the filter after the cooler. Seems like the cooler is the first filter and then the IPR. Is this correct???

 

The only places where all the coolant flows through the same spot in series is the water pump, and the radiator when the t-stat is open. There are four coolant loops after the radiator and water pump that all run in parrellel to one-another. Two are in the block, one to the heater core, and one through the oil cooler/egr cooler loop. All flow a roughly equivilent amount of coolant. The IPR filter gets plumbed into the heater core loop.

Long story short, there is no first filter. Some goes through the cooler, some goes through the filter.

 

I have absolutely no doubt that there is a reason for this but if there is a loop through the oil/egr cooler why wouldn't you put the filter there?

 

You can, there's even a manifold to simplify the installation.....however there is no way to filter the coolant before the oil cooler in the stock location, the oil cooler is in the engine block (basically) and gets its coolant directly from the block. Only way to pre-filter the coolant is to have a remote mounted stock oil cooler. Or better yet remove the whole clusterf**ck and use a bulletproofdiesel air cooled oil system.

 

It's worth mentioning that if you were able to stick a full-flow filter before the oil cooler, it would cut off flow to the coolers once it clogs up. This could cause problems if it doesn't clog up conveniently close to home. in some ways you are better off with a filter on the heater core loop.

 

True enough and I agree that anyone running an oil cooler relocation with the IPR filter before the oil cooler should definitely keep a close eye on their deltas, but you can remove the filter from the housing and replace the outer cover if it become clogged. The newer design actually has valves built in to allow for partial or complete bypass in that situation.





I personally do not see the need for the "OFF" setting and kinda wish it wasn't there. I'm sure someone will eventually select that and starve both of their coolers from free flowing coolant.

 

That all makes good sense!! I knew there had to be a reason :thumb:

 

I have the Bulletproof diesel air to oil heavy duty cooler with a Oilguard bypass filter along with a mishimoto coolant filter. Love my set up

 

OP I have a brand new in box sinister coolant filter I would make you a deal on --- let me know.
