Review on Design Engineering 010450 Titanium Shield by Brian Trujillo

I didn't get them on the first order but did get the ones that match the SPARK PLUG even though the description clearly says TUBE HEAT SHIELD. I sent them back to replace what I ordered. Shipping was supposed to take a month until I went in and changed the shipping method. Eventually I got them and went to put the first one on the pipe and I pushed the rivet through the "TITANIUM" heat shield. These things will be useless on a long journey. The remaining three rivets didn't even look for fear they would come out too. Have asked for a full refund. These things are terrible. Don't buy them!
