The K&N 57-9036 performance air intake system is a little different from the average K&N cold air intake system. K&N engineers chose to retain the use of the 2014-2015 Toyota Tundra 4.6L or 5.7L V8 stock air filter box when designing this system. This decision increases performance while leaving all the stock emissions control equipment in place, allowing the 57-9036 to achieve an exemption order (EO) from the California Air Resources Board (CARB) for the 2014-2015 Toyota Tundra models listed below.
2015 TOYOTA TUNDRA 5.7L V8 F/I – All CARB EO Number: D-269-52
2015 TOYOTA TUNDRA 4.6L V8 F/I – All CARB EO Number: D-269-52
2014 TOYOTA TUNDRA 5.7L V8 F/I – All CARB EO Number: D-269-52
2014 TOYOTA TUNDRA 4.6L V8 F/I – All CARB EO Number: D-269-52
