Another first from Earls are the adjustable LS steam tube adapters. The original GM brazed vent tube manifold does not take into consideration the aftermarket intakes and accessories we put on our performance vehicles. Replace the rigid hard lines with these adjustable outlet, O-ring seal adapters that converts to -3 or -4 AN plumbing. Earl's Steam tube adapters are the most adjustable and lowest profile available. These adapters LOOK as nice as they are installation friendly. There are 6 kits available to allow for the optimal routing on your application including at dual outlet option which eliminates needing a T adapter.
