WIX marketing doesnt blow up their image. They do have NASCAR but otherwise they are low key. But that doesnt make them second! They are the best in my opinion!

 

I've done a little research on this oil filter thing. After crunchin some numbers, I think a standard 318 Dodge oil filter will fit and WORK. If so, this would allow for a much larger filter. Actually a MUCH larger one, as the 318 filter is available in a one quart size, which is part number 51515 in WIX. Here are the numbers for the gasket size. The thread size is the same at 3/4"-16.

Stock 3.8 Gasket OD- 2.784
Stock 3.8 Gasket ID- 2.430

318 Gasket OD- 2.834
318 Gasket OD- 2.462

I got all these numbers right off the WIX site.

Notice the outside diameter of the 318 filter is exactly .100" larger than the stock 3.8 filter gasket. At first, you might not think that would work. Keep in mind two things. First, that's under 1/8". Second, it's less than 1/16" per side. Also, the ID is only .032" of an inch larger. I believe this will seal. surely, since it is the same thread size, there is no argument there. The only other point I'm not certain about is the clearance for the full one quart size filter. I know the half quart size will fit, and that's way bigger than the stock 3.8 filter. It's enough for me to go buy the 318 filter and give it a whirl. Just food for thought.

 

No...I got the engine clatter with Mopar as well......use a Fram and you won't hear it anymore.

 

Well, I did email them and received the following response.
I think it's a good response and hopefully they will find and alleviate the problem. I still have my old filter. Maybe I should send it to them to check out.

 

I have always been somewhat of a freak on oil filer/oil selection - I have several motorcycles that typically place high demands on lubrication. Here is a site that will provide you more than you ever wanted to know about filters:

I have always use K&N Filters but I got the clatter with it. Even spoke to the K&N people and send them the Filter. According to them the filter was tested and it was "within" operational parameters ! WTF
Change to 400s Motorcraft filter and problem fix .

 

I had the dry star with the Fram filter !!

 

And now I find out AC Delco is crap! I went to Autozone last weekend and they had a special on 5 qts of Mobile Super 5w30, a Fram filter, towels, funnel and drain pan for $19.99. So when I went back to grab a Fram filter they were all gone, so were the Mobile 1, Motorcraft, K&N and a couple other brands. BUT, there was one AC Delco PF53 left on the shelf. They substituted the Fram for the AC Delco for no cost. The clerk said all of that part number in Frams had a recall and they pulled them off the shelf. I didn't ask what the problem was. Anyways, I've never had a problem with AC Delco in all my GM products, hopefully I won't with the JK, but I'm switching to Wix when I change it again. They've always had a good rep.

Thanks for the link.

 

Hey Guys, quick question.
Whats the part number on the motorcraft filter? Having trouble locating it or maybe I'm just blind.
THanks.

 

A Motorcraft FL-400S filter, No startup clatter. The FL-400S is longer than the stock filter and has the good anti-drain valve. Hope this helps.
