Thanks for the response... I read here on a Saleen forum thread that WP346S is for the non supercharged 4.6
This guy stated it in the link attached below... Then again I don’t see why it should matter or play an impact whether the car is Supercharged or not. It’s a water pump and shouldn’t play a role
