K&N 57 FIPK cold air intake for 2004–2006 Nissan Altima 3.5L V6 and 2004–2008 Maxima 3.5L V6. A roto-molded HDPE intake tube increases airflow volume to the engine and the washable, reusable oiled cotton filter allows extended service intervals—up to 100,000 miles under normal highway driving. The system includes a custom heat shield, installs in under 60–90 minutes and is backed by K&N’s limited warranty; CARB status varies by part.
