JK Cowl Induction Hoods with side vents Our cowl induction hood is not only stylish but fully functional. Made from a special blend of high impact polycarbonate plastic and is extremely durable. The material is formed at very high temperatures. 300 plus degrees. The hood is a clamshell design with a full internal structure. The same material is used on commercial buses and is also used on over the road commercial trucks. The hood is designed to direct in outside ambient temp air from the rear of the cowl through a sealed internal duct system and delivers the cooler air to the air box. The side vents exhaust the under hood heat that builds up toward the rear of the engine compartment. This is the most efficient location for the vents. When the vehicle is being driven the air passing by the vents and helps pull the hot air from the engine compartment by creating a vacuum. We also designed the hood to be functional and not let water or debris get into the engine compartment. Due to the nature of the material that the hood is made from paint bonds to the plastic better than metal or fiberglass.
The hood looks incredible. I have had guys chase me down to ask questions. Basic install was easy however if you want your hood latch you will need to do some cutting. The cutting requirements are the only reason this did not receive 5 stars. 4Wheelparts price and fee in store delivery could not have been more convenient.
