IIRC the Evo IX OFH oil cooler ports are M18x1.5.

I am installing the Evo OFH and a Mishimoto oil cooler. The oil cooler comes with -10 an lines. I have never worked with AN fittings before (yes, I am that much of a noob).

Is this all I need to plug the oil cooler AN lines directly to the ports on the OFH?

Here is the oil cooler I am using and the lines that are included (I don't really want to use that sandwich adapter thingy that it comes with I would rather just use the ports on the OFH):

Thanks in advance I am learning as I go...

The cooler kit comes with all hardware to attach the lines to the cooler itself, you're getting the OFH, all that remains is the fittings to connect the OFH and the lines. Those would need to be M18x1.5 on the OFH side and -10AN on the cooler lines' side, precisely what the fittings you linked to show.

Looks like you're good to go! :thumb:
 
Make sure you get the manufacturer's recommended seal or crush washer for those fittings. And know that with those fittings, you will either have to remove or modify the plastic splash shield since the fittings will stick out too far.

Thanks. I realized that I just needed two of the fittings for the OFH side. Didn't specify that in the OP sorry. LOL. Figured that would be a given but I guess someone could be that stupid...

Wouldn't the 90 degree angle fittings go on the cooler side and then the straight fitting to the OFH? Still sticking out too far set up that way? This oil cooler is thinner than yours I checked the dimensions from your oil cooler thread. It is the same width (height the way we need to do it) but not as tall (wide).

I thought that I wouldn't run into any fitment issues with getting one a little smaller but I don't mind plastic getting in the way... I am getting used to it. I had to cut a bunch of plastic and metal to get my FMIC in...

Thanks for the info though guys. I didn't expect you, turbosax2, to actually chime in. I was basing my info from your thread with your oil cooler setup.

Edit: I will double check on any seals/washers they might need as well. Thanks. I thought I read that it creates a full seal on its own but I will double check.
 
I'm talking about the side connection at the OFH, not the cooler. Those fittings in the OFH will make whatever line you put on stick out far enough to interfere withe plastic shield there. I had to use banjo bolt fittings (which are thinner) to retain use of the plastic shield without modification to it.

Ok I get where you are meaning. I've never really liked banjo bolts. Never had good luck with them. I don't mind plastic being in the way. That is an easy obstacle to deal with haha.
 
Update for anyone who uses that cooler or OFH in the future:

Those fittings I linked to worked perfectly. We used some crush washers just to be safe and we haven't had any leaks so far. The lines that come with Mishimoto's kit are actually long enough to reach where the side mount intercooler used to be so we mocked up the position on both sides to see what we liked better. It looked like it would get way better airflow on the sidemount side and it didn't hang lower than the exhaust over there either which I liked also since this car is for street use as well.

I thought I read the dimensions correctly for the cooler that turbosax used but I must have been wrong because I expected it to be the same length but skinnier. It was actually a little longer so it hung lower.

The 90 degree fittings that Mishimoto provides work great if used on the OFH side. They clear where the tire would be if you were to turn the wheel fully to the right by about an inch or so.

For future reference as well if you use the stock oil pressure gauge and dummy light only one of them threads into the evo OFH. The other one we had to use an adapter for the different thread type. I don't know why they made the evo ix housing with two different threaded sensor holes that are the same size. The two larger 3/8 ones are identical but the smaller ones one is fine threaded and one isn't... Brilliant LOL. Not a big problem but I wish I knew that.

I will post pictures to my build thread of everything later tonight hopefully.
