Are air filters a bad idea?

[Special Coupe Frank]

Snyder's sells a "Hi-Boy" air cleaner kit, with a vertical riser, and the filter (K&N type) on top.

FWIW.

For me, when I spend four figures rebuilding any engine, I'm going to want both an air filter and an oil filter.

Even Old Henry allowed the new Model V-8 to go out the doors with a factory air filter...
