Considering that there are roughly 12 pieces of tape at probably $0. 015 each while oval cap plugs are on the order of $0. 15 each, you won't be seeing them anytime soon. For a mfr to increase the cost of a vehicle by a buck-fifty for over 100,000 units, it has to do one of three things: increase the safety of the vehicle, increase the sales of the vehicle, create a value-addded feature (meets emissions, etc). Cap plugs don't fit any of those qualifiers. Even off-shoring cap plugs to China will not meet the costs necesary to implement the cap plugs. Sorry, but that's the state of things for the time being.
