Threads should be copper greased on installation and throughout their lifetime. PROFESSIONAL FITTING IS STRONGLY RECOMMENDED. We sell over 250,000 performance car parts online!
Sadly, it is impossible for us to stock all of these parts all of the time and ultimately this would only lead to increased prices. Sometimes a part may have to be manufactured or even imported from another country for you. Where we are informed of a delay we will do our best to keep you updated. We cannot guarantee product availability.
Please do not schedule any work on your vehicle until you have received and fully inspected your parts.
