Review on 🔌 NGK (8691) RC-FX58 Spark Plug Wire Set: Superior Performance for Your Engine! by Inyong Dow

These connector cables have significantly less resistance than the old cables; I'm talking about 3-4 times less resistance. If I remember correctly, one of the old ones was around 10 MΩ and the new one was 2 or 3 MΩ. My old wires were fine, but they were high on the spec so were running out. These wires are actually lower resistance than the spec says, but in this case that's a good thing. I may have replaced my cables too soon, but whatever. OEM kits still ran at 145,000 miles. Very good processing quality. You'll feel a distinct click as it grabs the spark plug terminal. Lifetime warranty as long as you own your car is good.
