They noted that 90% of all of the contamination passed through an air filter happens in the first 10% of the life cycle. Changing a filter more often than necessary is a waste fiscally and detrimental to the equipment.
Short answer, yes, the more dirt in the filter the more effective the filter is. Unfortunately, more effective filtration means more restriction. As an example, my personal experience suggests that K&N filters are less restrictive but they let through a lot more dirt. It was more of an issue with carbureted cars as restrictive air filters made the car run rich. Modern cars have an O2 sensor in the exhaust which tells the cars computer to feed less fuel when there is less air available. Replacing the filter too early is really counter productive and a waste of cash!
Sounds to me like Warren drank the cool aid and bought a K & N filter. LOL I bet you are one of those guys that still believes Wix filters are ok to use on performance engines? As I used to tell my students, "you can fight physics as much as you want but you likely won't win".
Ah, that makes perfect sense, I used to know it all as well, then I became a professional and completed both my LD/HD apprenticeships and then spent 22 years running a chassis dyno. My specialty was advanced diagnostics for gas/diesel. I've probably logged more miles on the dyno than most folks do on the highway testing this stuff.
Look, I get the fact that not everyone devotes their life to automotive tech but this is basic stuff, even a first year HVAC technician can grasp. Perhaps in future, if you don't have anything constructive to ad, you should just skip over the technical stuff as we have some folks here that actually want to learn the basics. Just a thought. Not trying to hurt your feelings but calling BS on something because you don't understand it seems a bit immature for a man of your years.
Just in case anyone was wondering, I still consider Warren a respected fellow hobbyist and I would not hesitate to buy him the beverage of his choice the next time we cross paths. I hope he feels the same? Just the other night we were both at the theatre and someone snapped a pic. Passion for hobbies is a rare find these days.
I luv my Wix Oil filters and if i can't find them then Purolator . i do not allow fram on the property
I used to say that too. Then I saw a guy cut apart a new Harley Filter , an old Harley filter and a new Fram.
Fram is the only one I can find that still made in USA.
If the Fram was better than the HD units, the HD units must be total junk.
If they are being made in the States, they got a close eye on the production and the people making them are given the materials and specs how to do them. Sad.
NAPA Gold filters are made by WIX and are virtually the same and cost less. I'll be there for that beverage. I wish I had seen the article before. Spent the weekend at the Jalopy Jamup, drank some beverages, met a lot of great people and hooked up with old friends.

Warren, look forward to it! On the filter subject, I'm not sure you can go wrong with just about any mass produced filter these days. Even the "white box" units seem to do a pretty good job as long as you don't try the "extended oil change intervals" which have become stylish. My only issue is when a stock filter is used on a high volume oil pump. Years ago I built an admittedly unscientific test rig using an external HV oil pump from a 440, and ground down distributer drive, my drill, some 20w50 oil and all the shavings from my drill press. On the stock filters, the same crap that went in came right back out suggesting that the bypass was opening. (no idea what RPM I was spinning at though) Using the HP rated filters, only clean oil came out suggesting the oil actually went through the filter media. No filter on earth will keep the bypass closed on a cold start or when the thing revs to 6k but i'd like to think it is closed most of the time. This diagram explains the filter bypass operation better. When I apprenticed with Volvo, we used the dreaded "orange can" Frams on every vehicle. Several cars got the "million mile badge" so they can't be all that bad.
Actually, I have to disagree with you. The Chinese have manufacturing plants that put us in the stone age. The quality of the product is determined by the demands of the US/CDN purchaser. How much do you want to spend. In an effort to have more at a cheap price, we formed this mindset that we should ship all our jobs to a place where as consumers we didn't have to pay much. It was junk at one time, but in order to keep our business, the third world has stepped up their act. Now we work for $16/hr as waiters.
Warren
USA parts are not what they used to be, I've had no end of grief with US Reman units and US electronica and at work, it usually the US tires we have warranty problems with. Chinese manufacturers like Michelin seem to have their act together as far as quality is concerned. Delays of up to 8 weeks are not unusual now though. Chinese casting seem to be the exception to the rule, seen some bad master cylinder/calipers.
Chinese plumbing clamps aren't worth a penny. My Chinese drill press packed it in (Mastercraft). My Chinese ratchet broke in two.
But if my mentor says things are improving, it must be true. I hope so. Hard to find anything that isn't made in China these days.
My next purchase is a wiring harness from Rebel wire. I think Canadian made. Or should I just wire it myself ? Hmm ?
Everything other then bread is made in China, probably even the fuse panel of your wiring harness. Products can look the same, check the reviews, don't always go for the lowest price and make sure it come with a warranty commiserate with the cost and the expected work load and lifetime. Remember, this ain't 1954 anymore. Everything is disposable.
Warren
I didn't go for the lowest price with my triples. I'll check reviews and get a fair warranty. First comes more research and spend the time saving pennies just like before.
I try to buy North American made products when I can. I don't have a problem paying a bit more for them either. I live in Canada, most of my friends too. I work in Canada and pay Canadian taxes. So I try to support them. Yes , it's true trying to find stuff that isn't made in China is hard. I don't have a problem with Chinese people, I have a problem with the government over there. The human rights violations are horrendous. Buying from them just supports it.
Not trying to make this a political post, just giving reasons for what I buy.
