Fast delivery. When I've put it I've start immediately the engine and went for a ride, this air filter gave more reactivity into my seat; for it's a very good surprise cause my normal mode is now as the sports mode. So it's working well, I'm just waiting to see if that' gonna save the fuel economy.
