Critical Note: Always verify using an online fitment guide or your owner’s manual. While the Denso 5285 fits hundreds of models, it is not universal. It is generally used for naturally aspirated 4-cylinder and small V6 engines, not large V8s or forced induction race cars (which often need a colder heat range).
When you pull your old plugs to replace them with the Denso 5285, examine them. The condition of the old plug tells a story: denso 5285
Why does Denso use the "Twin Tip" branding? To understand that, you need to look at the history of spark plug metals.
