Air Filter Comparison

If a car manufacturer only had to change air filter design to gain more horsepower to advertise I’m sure they would spend an extra 20cents to do so. It’s rare, even for cold air intakes to get better power.

You clearly haven't met the bean counters.

Lay people do not realize that a new air or oil filter is much less effective as no loading of the filter media has taken place. Consider that after XX hours of engine operation and with some loading it is important that sufficient air or oil can pass through the filter so when new the media will filter the least in terms of particles passing through.

My own experience is that the OEM filters fit better and so perform better than aftermarket filters whether from K&N or Fram or others.

I mean, Ford still puts incandescent bulbs in the license plate light.

But Ford give you multiport fuel injection and direct fuel injection (two injectors per cylinder)when all other truck manufacturers only give you direct injection which is huge! Ford also gives you a deep breathing DOHC V8 engine or powerful and stout turbocharged V6 engines when others give you cheaper old school pushrod (single cam) V8 engines, turbocharged I-4 engines, or straight I-6 turbcharged engines of which all are big cost cutting measures. Ford also gives you 400-700 pound lighter aluminum bodies that dont rust and increase performance and capability which is an expensive thing to do for a manufacturer. Ford actually gives the customer a lot of technology where it counts for their money. ?

Amen. I was always a Toyota guy. First non Toyota truck is 22 3.5 and i absolutely love it. Love how trim levels you can get and the price range. I got exactly what I wanted, the most basic package with 4x4 4 doors and stx and it was like 52k tow package as well. No intention of racing it, which I did a couple times. In the factory wheels and tires with a tune and intake upgrades only and my daily driver tow/haul work truck ran 11s blew myself and the whole race events minds.

Having gone deep enough down the HVAC filter medium rabbit hole, I know not all filters/filter medium are created equal.

Based on recent research, it is safe to surmise you will have a hard time improving flow rate over OEM without sacrificing particulate filter efficiency, however, it appears possible, both WIX and Purolator appear to offer filter media that is as effective at particulate filtration as OEM whilst providing more filter surface area for a potentially higher flow rate.

Will either correlate to a better torque or HP, unlikely, are they a comparable upgrade to OEM, Yes.

What specific "research" are you referring to, exactly? Anyone can make a statement such as yours that has not support by science. Fuel filters are not important for gas engines but critical for the life of the fuel injectors when burning diesel fuel. Air filtration is well studied by those in the HVAC industry where exact numbers can be produced for different media over its life.

What muddies the water is all the advertising by third party manufacturers who want people to believe that they have something magical that no other company has and so is worth paying a premium price to get. That is certainly the case with Amsoil and K&N and it has contributed greatly to their profits.
