This is a true 3" diameter tube intake, unlike other intakes that only claim to be 3". We chose to make these from 304 stainless steel and to make them two pieces. This is because the aluminum intakes on the market were wearing holes into them and the one piece intakes don't fit well. These typically gain 5-10 hp and greatly increase the sound of your supercharger.
This intake is built to order and takes about 1-2 weeks to ship.
