Review on πŸ”₯ QUWEI Car 1200 Degree Spark Plug Wire Boots Heat Shield Protector Sleeve (SBC BBC 350 454/Coil On Plug Boots): Ultimate Protection for Engine Performance by Ricardo Knight

Revainrating 5 out of 5

This damn good job of protecting my spark plug wire sheaths

Benefits - They protect your boots and forks. that they are 2 stars for what they are not. These protect my spark plug wire shells damn well, for a cylinder where the shell touched the manifold they do a great job but cannot break the laws of physics, putting spark plug shells next to the manifolds protects them and makes them much longer lasting of spark plugs and covers. If you have aftermarket fittings and your boots are touching the header, you need ceramic jacketed cables.
