My new Air Filter issue

[H. L. Chauvin]

One concern keeps coming up about former experiences with former "small" Model A air filters which in the past reduced air flow -- these past sincere concerns definitely have lots of merit.

K & N in their on-line literature correctly describes something I learned about hydraulics over 46 years ago.

As crazy as it may appear to some, air filters & devices on the suction end of a round pipe, (such as a Model A carburetor), can "increase" air flow & even increase water flow in water "if":

1. The device has the proper & sufficient "open" areas for air and/or water to flow; &,

2. If the device can assist in retarding turbulence & cavitation of air and/or water in something like the end of a round suction pipe.

FWIW: Opinions:

Just because John Doe is afraid to open an umbrella in a house ...... what the heck ..... buy him a beer ....... he may be the best friend you may ever have.

Then do not be surprised if you later open your umbrella in your house & your air-conditioner immediately breaks ....... sh## can "still" happen whether you open your umbrella ..... or after you install a Model A air filter.
