There‘s a KN intake for a 3.5 but doesn‘t work for the 2.5
The only thing a cold air intake adds to a computerized engine is the sound of the intake. Cold Air Intakes (CAI) are terrific in theory, and worked great before cars became computerized. With the advent of fuel injection as standard equipment along with computerized fuel / air control management, cold air intakes are no longer even feasible. The basic problem arises when you start making changes to the air intake, you also cause the computer to attempt to adapt to the new intake system, altered airflow and temperature of incoming air. You'll frequently have problems with your sensors when changing air intakes from stock to the after market intakes, and usually the only positive that results is the sound of the air intake. Performance is very rarely affected in a positive way by using an after market air intake since the computer will attempt to restore the original settings based on the original intake system for which it was programmed.
