The shop that does all the major work on my car isn't a believer in the IPD plenum and larger TB. They recommended against it for my car both when it was a stock 3.2 and again after they rebuilt my engine as a 3.6. They said they've never seen much of a power increase on the dyno after installing one, and have actually seen power decreases in some instances. They also told me that the 68mm throttle body on the 3.2 was big enough, it was also used on some BMW engines of larger displacement. So for now, I haven't added it to my car.
