Hi David, That depends on how many cylinders the vehicle has and how many need replacement. For accuracy of fitment - On the Homepage, please enter (complete) your vehicle’s year, make, model, sub-model, and engine size. Type the part's name in the search box. Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
