If you look at the picture you will see a tube with a white connector on the front of the airbox connecting to the throttle body. The 05 injen intake has only connectors for the 2 side tubes. I went to home depot bought a 1/2" t-connector for 1.78 and 2 feet of tube from autozone for 1.19 a foot. I had hose connectors so now all 3 tubes are connected. I taped teh third tube because it has a sensor attached and i didn;t want it to come loose. So far so good and not throwing any CEL's. I love the intake so far. Sounds mean and pulls great up top.
