Best Answer:Hi Walter, I'm glad to assist you. This is on the upper or usually called upstream location, on the intake location. The lower or also called downstream, is located on the exhaust portion. Still, it is best to refer to a vehicle-specific service repair manual or consult your trusted local auto repair shop for this. If this is what you need. Grab our discounted offer with 67% off already. Click the link below to order today while on sale.
