I’m getting Hazet from https://www.jensputzier.com/. He’s a GJ member. All three orders I have made with him arrive in 3-4 days by DHL. Very happy with his service and price.
I changed mine on my 2005 5.4 at 50K too. I put the one piece Champions it it. So far- 75K later they are working fine. I'm going to change them out at 150K.
