If you are in Seattle,it came out of John vanRensburg's red car, I bought his car, and then we did the conversion, so I personally only did about 60 days of driving on it. Let me get more information from him on the previous service etc. It drove great and smooth before I removed it
Have been gone for a couple of days on the boat. Got back just before the lightning storm on the Sound. Hate to be out on the water with our small sailboat with it's lightning rod mast, lol. The wife, being a lightning theory expert, gets pretty jumpy about that situation. I don't blame her.
