Long style filter or shorty? Which would you prefer?

[resq302]

Here is a question I have been pondering with lately.  I know that around 1971 or 1972 Chrysler changed over from the L-72 (1851658) long style oil filter to the "shorty" filter that was not as tall but still had the same thread size and mounting area that screwed on to the fitting on the block.  If you had both styles available to you which one would you use?  Is there any harm in having a little bit shorter area for the filter media or would it not necessarily matter as long as it is still filtering like it should down to the set microns that both filters say they filter down to?

After I get your thoughts and replies, I'll post further where I might be going with this.......

in the land of supersessions, mopar has changed them all to the shorty. basically comes down to preference and or belief.

Not an expert but it seems like more filter area would always be better than less.

That's my thoughts too?

Has to be true, think about it.  If you put a AC filter in your house that was 1/2 the size wouldn't it need changing more often.

Typically, it's surface area that matters.  So you can have a smaller filter that has more surface area and is more effective than a larger filter.

The same principle applies to cooling, which is why some smaller radiators are more efficient than larger ones.

Not necessarily true.  You could have the same amount of dirt flowing through the house and being caught by the A/C filter no matter what size it is.  If it is suggested that you change it twice a year like my force hot air and a/c system suggests, I change it at the recommended intervals.  I would imagine if it is shorter and that is what all the newer cars are using that it would not be any problem with filtering.  Like Jamiez said, it could also be due to the surface area and better filtering media that todays filters have.  Granted, I don't put anywhere close to 3,000 miles on in a year (I'm lucky if I break 2000) but I change my filter out every year. My daily drivers get the oil changed every 3000 miles along with a new filter.

A long Fram filter will have less surface area than the mini 2.2 filter from Wix , at least wix still has a quality product .

Ok, here is the reason why I was asking for everyones opinion.  I am in the early beginning process of coming up with a slip on cover that will slide onto a current modern day filter (brand of your choice of your choice) that would have the exact correct appearance as what the green textured assembly line oil filter would have been installed at the factory.  This way,  you would have to only buy the sleeve once and then just replace the actual filter under it whenever you wanted at a much cheaper price than what it would be to replace an actual filter that looks like the assembly line one.

What is everyones thoughts on this?

Granted, I don't really know what we're talking about, but wouldn't the slip-on cover for the larger filter fit over the smaller filter too?

[resq302]

Plum,

Yes, for the sleeve to work and appear like it should (like an actual original filter) it would need to utilize the "shorty" style filter.

Food for thought, pretty much every header available requires the use of the shorty filter. Although I suppose if you're worried about your oil filter looking stock then you probably don't have headers.

I only use the longer filters 51515 Wix

[dutch]

I tried to get the wix 51515, but not available through wix europe... didnt even know it     ended up using a K&N HP 2003.  This is a long filter, the hp 2004 is a short one but has the same specs...

[resq302]

Here is a teaser of the prototype.  I forgot to take a picture of what it would look like totally hidden in the "shorty" filter.  The fit is exactly the same for the Purolator L30001 vs. the "shorty" Purolator L14670 with the shorty being able to be totally hidden by the sleeve.  Keep in mind, the L30001 will have the sleeve slip over the filter as shown but will not cover the bottom 1" of the filter due to the knurled part having longer flutes than what the Purolator filter does, hence the need for a slightly shorter filter.

Again, this is only the prototype so far and once I secure a source for the sleeves, the ball can be moved forward with Chrysler and licensing and such.  I would also need to know what kind of interest the general hobby would have as with anything, if there is not enough interest, it obviously wouldnt be cost effective for everyone.
