The comparison of intake systems between bikes and cars is a good one, as they are both gas powered engines, they both use tunned cold air pressurized intake system when the vehicles get up to speed on most sports cars and sport bikes.

These systems were first pioneered by Yoshimura on there factory race bikes in the late 80's and was introduced functionally as a ram cold air system on the new series 1995 GSXR750's

Some will argue that the early Mopar Grabber Hood was the first factory cold ram air system, but it didn't use a tunned cold air duct system.

Also externally oiled cleanable air filters were first used on motorcycles for years before they were ever really used for cars.

Now if you a large amount of dirt can be sucked into a small 600cc-1000cc bike engine then think how much more air sucked in by a 5.7 liter engine or 5700cc car engine. On regular paved roads.

Remember your comparing 1000cc gas powered AIR PUMP to a 5700cc AIR PUMP, which one engine would produce a dirty air filter or restricted air filter, if both engines are stationary using the same airfilter and run in identical outside air conditions and run at the same rpm. Logic would tell you the 5700cc engine would need the airfilter replaced sooner than the 1000cc engine.
