Just installed this thing in my 3.5
I just wrapped my manifolds which strangely reduced the temputure by a lot. It seems to stay cool under the hood now. I am running the piping and filter inside the bumper so it’ll be more air flow.Probably sounds better and lost power. Warm air is less dense so less fuel mixes in the intake charge. The 3.5, 3.9 and the 5.3SS use the same airbox and filter. The stock air system provides colder air and is capable of feeding a 5.3 V8 with 303 hp.
Nice set up. I just ordered more pipe to either run in through my fender we'll. Or through my front bumper. Also got 30ft of cool tape to keep the intake cold down.
