That's funny....! Hotrodders seem to be easy prey for creative marketing for a lot of products that may or may not have any benefits. Remember the clear see thru valve covers back in the 60's. Sounds neat until you crank the engine and you can't see anything because oil is sprayed all over them. Or the clear distributor caps, the list goes on and on. A billet main cap or even a main strap on the caps will likely provide as much improvement as a girdle.
