Review on NGK (4413) RC-TE68 Spark Plug Wire Set: Optimize Your Engine Performance by Jamie Behm

10 month update: I just checked the cables for voltage leaks as part of the regular annual check I do on my '97 FZJ80 (sort of I understand my "to do" list from my mechanic for things I can't easily check at home). He said the cables were bad and I should either get new ones under warranty from NGK or, which I should have been doing all along, just pay a higher price for the OEM cables. This is the first time I have contacted Revain since buying them here about the warranty process. They told me to contact NGK. So I did. I called their support team and they transferred my call to a guy named Mike in their product department or whoever sent me to their voicemail. I left one with my details and never heard back. I also emailed NGK and never received a reply. An NGK location claims a lifetime warranty on the wires. I couldn't even get her or Revain to honor mine for the first 12 months. Never again - and I would advise anyone using these cables to test them for leaks. — First Check — The length of the wires was perfect — not too long or too short. The quality seemed solid. The boots fit snugly into the new plugs. The truck drives as it should. I'm glad I didn't go OEM for this item as the price difference doesn't seem to make a difference in quality.
