Airaid 91-06 4.0L Jeeps PowerAid TB Spacer Suspension>Air Tank Components Pliable polyurethane bump seal insures

Pliable polyurethane bump seal insures tight

strong as steel but much lighter and corrosion-proof

This air intake system was developed to accommodate the engine's factory emissions control devices including the intake air temperature sensor and vent line

powerful sound on acceleration but maintain a smooth sound at idle

in a brushless motor the magnets rotate around the armature and the motor controller manages the phase shift to keep the motor rotating under load (load is related to pressure in a fuel pump)

The spacer utilizes it's unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer. The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air fuel mixture as the air charge enters the combustion chamber.
