First question - I should be able to use the Ford Racing FL820 oil filter part number is CM-6731-FL820 oil filter in my car, no?

I have looked closely and it is on many web sites this filter will fit my car. I am not sure the differences but I purchased some of these filter due to believing they are an upgrade.

I received my Mishimoto oil cooler kit from American Muscle. Alex cam through with great customer service and got me the cooler kit.

It appears to me the sandwich plate does fit the FL820 filter.

Has anyone been on this path before me and can they offer some guidance on my question/concern? I will not be able to contact Mishimoto until Monday.

The filter is the correct part number right?

Am I missing a better solution for oil cooling and ports for gauges?

Thank you in advance, john

SHOSKER's install shown using the 500 motorcraft filter. I guessing that is the issue. I am not sure what I am going to do at this point. Would love to find a quality oil to air cooler for my project. I have searched around and have not found any other option that used a thermostat to control temp.
Sorry for the delayed response! I ran out of time yesterday to check these filters, but managed to sneak out today and grab some measurements.

Interestingly enough, the 820 filter does indeed have a larger O-ring, which is what is causing the overhang. Dimensions below.

OD: 72.75MM
ID: 63.35MM
Width: 4.7MM

OD: 69.75MM
ID: 60.35MM
Width: 4.7MM

Our kit was built around the 500 filter and I would not recommend using the larger 820. While the 820 might fit just fine on the factory oil filter housing, the footprint on our sandwich plate is smaller.

So, a 500 filter should solve this one for you. Samantha will likely be reaching out to you by phone or email today to pass on the information. In addition, we should probably add a note to our site indicating the 820 filter should not be used.

Let me know if you have any additional questions!

That's the one!
