• Is it there to prevent rubbing/ chafing of the cable?

  • Maybe? It obviously doesn't do a great job on pre 2012 1.2 TSIs before they made the modification that kept the lead a bit more distanced. I guess I'll just get used to checking it every couple of months. Might also buy a spare set of leads to have on hand should it happen again.

  • You can get braided fiberglass boots that do a ok-ish job of protecting HT leads from heat. I’ve had decent luck with them.
