Correct Air Filter Elements

[RALPHIE]

For some time now I (& other owners) have been unhappy and dissatisfied with the air cleaner elements recommended by Ford as the replacement for the original items that came with the car. The original equipment installed at the factory used a orange colored elastomer for the sealing gasket, whereas the recommended replacement, P/N FL 1682, uses a black gasket material which is definitely not as soft or pliable as the originals.

Two problems noted with these replacements are (1) they don't seem to fit into the Air Box without trimming the gasket material, i.e. the gasket is too large, albeit slightly, and (2) the gasket material has been noted to defray and/or deteriorate to the point (in a few cases) of going through the supercharger and winding up under the intake manifold on top of the intercooller. A third dissatisfaction of mine has been the fact that the filter "leaves" of the Ford replacement part run perpendicular to those that originally came with the car. Clearly, this recommended part is not a good choice for our supercars.

Picture 1 is one of the filter elements that were installed on my car at the factory.

Picture 2 is one of the filter elements of the Ford recommended replacement, FL 1682.

Clinton, aka BlacICE, has found a replacement filter element, Fram P/N CA 8958, which uses the original-type orange sealing gasket material and which seems to fit nicely to the Air Box. However, it also appears to have the filter "leaves" perpedicular to that of the original filter elements, and that it uses a white element. See Picture 3.

I just replace mine with Fram filters. The fit was as good as OEM. The gasket material is orange like the original air filters. Amazon has these for an super price of $5.40 each.

Similarly Lorenzo aka Lorenzo has mentioned a couple of times of a NAPA filter element , P/N FIL 2572, but there has been no other information about it.

There is also a NAPA Part # 2572 and i believe WIX makes it for them.

Recently, because we have a NAPA store here in Mammoth Lakes, I logged onto their website to see what they were asking for the Fram filter, but instead was directed to their own product, P/N FIL 2572. Looking at their picture (See Pictures 4 & 5), it looked like their product was identical to our original elements - an orange elastomer gasket with longitudinal filter "leaves." It also seems to have the correct treated element material, an orange looking paper. So, yesterday, I ordered a pair of these filter elements, and, upon their arrival today, found out that they are identical to the original items installed in the Ford GT, as shown in pictures of next Post.

Correct Air Filter Elements - Continued

Picture 2 shows the NAPA FIL 2572, Backing Side

This filter element is the same as our originally installed pieces at the Ford factory, and, it falls into place in the Air Box with no interferences or other problems. They do cost about twice the price of the Fram filters that BlackICE found, but they have the "leaves" along the correct axis, which may give slightly greater air flow due to the location of the air inlet (from the outside) of the Air Box.

Upon opening the second box, I then found that this filter was slightly different than the first - in that the metal web backing had more open space (a higher transparency) than the 1st one which was identical to our originals. Picture 3 shows the difference between the the metal support backing of the two elements, which are sold at NAPA under the same Part Number. The element on the right is identically correct with our originally installed filters.

So, if you want to put in filters that look and act as our originally installed items, you may have to look at each filter prior to purchase, to ensure that the backing spacing of the metal lattice is correct. I'm just happy that they both look like our originals, and that they fit properly with what appears to be the proper gasket elastomer, and that the filter sheaves are pointing in the correct direction.

We use the Fram filters unless the customers specifically requests K&Ns. We have not had any fitment problem with the Frams.

Air Filters

I would not use the K & N 33-2317 air filter; I would use the AFE 30-10100!!! It has more surface area than the K & N !!! :thumbsup

That is what i have in my Gal. I have checked them twice this season to make sure they are not falling apart. I am pleased to say they are still in perfect condition.
I woud be willing to bet they are made by the same Vender as the O.E.M.

Andy do you prefer the AFE 30-10100 over OEM type paper filters? Which type flow better when new?

 

[06fordgt]

Ok I bought the fram filters as well. Haven't checked them yet but I will. The question I have is how do you take the top off to change the filters? There about 6 or 8 screws whcih are not easy to get to. is there an easy way to change the filetrs?

Remove the complete air box; there is a 10mm bolt on bolt sides, loosen the stainless steel band clambp near the air box, unplug the KAF sensor plug, to do this lift slightly on the red tab and then squeeze the end and it slides off. Then lift the air box out; somtimes you will need to tilt it towards the bax to get it to break free of the rubber grommets and then carefully lift it out. Once out turn it over and remove the Torx screws, off comes the lid, replace the filters and reverse the operation.

Any questions or issues please let me know and I will gladly assist.

[06fordgt]

Shadowman Thx. It will be eisier to remove the screws holding the lid this way. I thought there was a simpler way but I guess not. I have taken the air box before so I am familiar with that procedure .
Thx again.

 

[06fordgt]

I have checked the filters. Sorry they are napa not fram as posted earlier. The part # on the box is 542572. Both are the same withe the smaller metal grate, orange "rubber" and the filter paper running the OEM direction. Iwill installl now that shadowman has explained the process to do so. I will report on the original OEM filters as they are still in the car.

AFE 30-10100 Air Filter

The AFE flows more than the Stock paper filter. AFE also makes a non-oiled filter 31-10100 too !!! :thumbsup

 

[PHXGT]

Wouldn't we get better air flow with the Napa version that has the "wider" metal grate?

 

[MTV8]

The pair of wix filters that I ordered both came in with the wider metal backing. It may be that this is how all of the newer stock will be.

 

[MNJason]

MT, any issues with those WIX filters? Im getting ready to order a few.

 

[MTV8]

No complaints. They fit like stock in the airbox and seem to be functioning well.

 

[The Grey Ghost]

Just ordered 2 from NAPA (542572) and they both have the black rubber.

Manager tells me it's a crap shoot.

Since they don't stock it, they are a little reluctant to keep ordering them in until they get the orange ones, and the chance of getting someone at the warehouse to go through them them before shipping is out of the question.

I just ordered two WIX from RockAuto and they have the orange soft rubber and long (OEM) run filter material. They appear to be identical except with the larger screen openings, which I like.

I'll let you know how they fit. They were like $8 each.

EDIT: They fit perfect and appear to be 100% correct other than the larger screen openings.

I also just picked up a pair from NAPA, and mine also had the black rubber - don't think its the same as the Ford parts though, as the paper is folded in the proper direction.

My manager also told me the same.
