DO NOT use spark plugs for a turbo engine in an NA engine!!! Make sure you use the correct plugs for your engine. Sometimes this changes for SULEV and ULEV cars too. So check with your dealer via your VIN. There is no magical secret power to be found by using different plugs. That was a myth used to sell those V-grooved plugs from years ago.

Just by changing your old worn spark plugs, your engine will feel stronger. Always use OE spark plugs!

So just follow what the box says? I always thought the myth was true about the plugs but thank you for responding

It really is. You can read up all you want about how to please a woman, you can look at all the diagrams in the world, but just like the clitoris, you won't know what the hell an apex is before you actually find it.
