I already have the correct tube seal spark plug ends (boots) from my current date coded repro set, which I'll re-use. I need new wires because the ones in my current set are too short. The Denso 6716132 kit does not have the correct spark plug boots. It has plastic discs that slide up and down the boot. Many, many sets have these incorrect boots. The only sets that I've ever seen with the correct factory style boots are the repro date coded ones that you can buy from the repro parts guys. Furthermore, ALL of the aftermarket sets that I've tried - all of them - have cables of the wrong length. So no, I don't think making my own cables with the factory correct boots is a total waste of my time.
