【Stainless Steel Construction】 Features a stainless steel outer body and ceramic zirconium sensing element designed to withstand normal exhaust heat, carbon exposure, and operating conditions on compatible vehicles.
【Important 2.4L Verification Step】 Formulated exclusively for 2.4L 4-cylinder naturally aspirated gasoline vehicle variants. Does NOT fit 3.0L/3.6L V6 engines or Turbo/Hybrid editions.
