Kaase Intake Manifold
The new Boss Nine intake manifold is a single-plane unit that stands just 1 1/4 inches taller than stock, and can be used on either Kaase or original heads. Available with either a 4150 or Dominator flange, dyno testing has found this intake to be worth big power over either a period NASCAR spider intake, or the stock dual plane. Unbelievably, on a stout 466-inch mule, the Kaase intake was worth about 50 hp more than the NASCAR piece and 100 horses more than the stocker.
