Review on 🔌 NGK (6403) RC-TE132 Spark Plug Wire Set: High-Performance Ignition Cables for Enhanced Engine Performance by Terry West

Just installed this on my LS400 today. They fit so well that you would never guess they aren't factory made, aside from the obvious fact that they really are light blue. The connector caps are larger in the area where you take them for removal and installation, otherwise they fit. as from the factory. The only thing I can fault is the marking of the cylinders. These wires are marked, which saves a lot of time when routing a route like the LS400 (a place for everything and everything in its place), but it's just a numbered ring at one point on each wire. In comparison, the factory wires have the cylinder number markings printed directly on the wire itself, both upside down and upside down every few inches! This might seem like a frivolous detail, but it really helps to route the wires and check the installation so those marks are everywhere. So I have a solution: install one wire at a time, one guide slot at a time. It's a bit more work than tearing them off en masse, and when you're done there's a very small chance of winding a wire in the wrong guide notch and virtually zero chance of cylinder mismatch. On one of the wires I had to cut off the protective polyhelical sheath that is wrapped around individual sections of the wires. In just one place out of many was the scabbard 15mm longer, interfering with the guide notch. I unfolded it just a few turns and trimmed off the excess with scissors. Otherwise no problem.
