Review on NGK (9343) RC-NX97 Spark Plug Wire Set: Optimal Performance & Efficiency by Danierl Temple

Installed on a 1994 Nissan D21 truck with a VG30E engine. Matches OEM well, each wire is marked for cylinder and correct length. I don't particularly like the flexible rubber on the shorter guard/sleeve compared to other premium brands, but the quality of the materials seems to be above average. However, the spark plugs hold very well and snap into place with a little effort. Replaced an 8 year old premium cable installed by BOSCH where a bad cable could have caused a choppy idle.
