Prestaged all the intake to be installed. Placed split hoses to hold the bolts up. With the rails on, you have to put the split hoses between the allen bolt head and the washer. I tightened all the AN hoses as well before installing it. Everyhring is nice and tucked in against the intake to slide under the cowl. I capped the rear vacuum port, the front purge port, and the throttbody top port.
