intake manifold
This intake heater protrudes directly into the air stream in the cold side of the intake manifold and blocks approximately 20 percent of the intake path. While the design and use of the AIH may have good reasoning behind it, which is to heat incoming air to alleviate white and gray smoke while the engine is cold.
