When do you usually replace them? I have 46k miles on my car.

Don't forget ECSTuning....I've used Lemforder and Meyle both perfect fitments. FYI I had FCP beat a price of the same item from ECS, I was already ordering other items so I just told them I needed another part but it was cheaper on ECS. Pretty sure ECS would match or beat FCP also...
