Well, thats a carburetor setup there on the test rig plus an 8 liter engine. Not typical at all of most Americans. :surprise
Did you hear the preface video where they say one of those dudes do not run an air filter and changes the oil more frequently before he reveals what amsoil oil they use before the test? Ive ran a lawnmower without a filter and ruined the engine. I had a honda with a kn from the start and at 100 k miles it looked like it was sandblasted from filter to cylinder. No more kn for me.
