You guys are great entertainers when it comes to filters at least to retired filter peddlers like me. I've been flown to (via corp jet) and gone all through Baldwin's lube, fuel and hydraulic "filter plant". Left no doubt and they confirmed Baldwin makes the large, heavy duty and industrial filters they simply sub-out all the filters common to the automotive market (ultra competitive).
This thread starts right off searching for recommendations on a shorter spin-on filter. You can't have your cake and eat it to. Odds are great there will be less filter media in a shorter filter. Unfortunately increaseing the amount of media EXPONENTIALLY and directly improves the performance of the filter in every measurable way that filters are rated. Contamination capacity , restriction, flow:differential pressure, and surprisingly even the sizes of particles captured etc.. Conversely decreasing media does the opposite of increasing it in all aspects.
For the life of me I find it hard to comprehend why "laymen" get into such elaborate discussions on both oil and to a lesser extent air filters while they don't even put forth a tenth of that effort discussing gaskets, oils, carbs, headers, mufflers, tires, gears, pistons, cams etc.. I've sold over $25 million worth of filtration and get educated on filters all the time by laymen. I'm especially amused by the never ending hoards of snake-oil filter advertisers.... you know the ones that say: filters down to, filters as small as, increases HP & Fuel Mileage etc.
I was requested to do a speech for a group of ASHRAE engineers on antimicrobial treated filter medias. One engineer came up after I'd talked and said he liked my using the: "It filters down to a half-micron and so does a chain link fence if you find a half micron particle somewhere on it.'
Qikbbstang, what brand would you recommend? I like hearing from people in the industry. I figured filters, like most products, are manufactured by just a handful of companies and built to the label's specs.
