The car is dropped down and Brian concentrates on finishing the engine bay. The coil pack and wires, ATR downpipe and external wastegate, breathers, and the intercooler plumbing are installed. Cotton's decided on a 4-inch intake pipe for this application, and young Cotton fabs it up. Brian used a saw to cut into the plastic below where the original air filter assembly was for the new intake system. From here, the radiator hoses and the MAP sensor connections are made, as are all of the vacuum, fuel and electrical connections. A trans cooler is mounted underneath the intercooler, and a Moroso line-lock is spliced into the brake lines. The next time you see this Buick, it'll be at the track!
