The Volant intake we chose for the Blazer retains the hose that connects to the throttle body, so after the stock intake was removed, we were ready to get the install started. It took less than a half hour. A new airbox bolted in right behind the driver side headlight, the supplied filter fit right in, and hose clamps secured a connector to the air hose. That's really about it. We like parts that go on easily!
