      Sorry, the K&N Universal Chrome Filter - Part No. RC-3680 is not compatible with your 2012 Toyota Tundra with a 5.7L Engine. Unfortunately I do not see any other universal type Air filter available for your vehicle. Please check the K&N Panel Type Cotton Gauze Air Filter - Part No. 33-2387 which would be an exact fit. Locate the air filter housing unit on the passenger side of the car, in the front corner. Look for a black, plastic box that has an accordion-type hose attached to it that leads to the engine. Open the lid on the air filter housing unit by loosening the clips that hold it in place. Lift the lid off of the unit. Remove the old filter from the housing unit by lifting it out. Use caution to not dislodge anything from the filter. Clean any remaining debris out of the air filter unit. Wipe the inner and outer surfaces of the housing unit with a damp cloth. Replace it with the new Air filter. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.
