🔌 NGK (9160) RC-ZE21 Spark Plug Wire Set: Efficient Ignition Performance Guaranteed Review

I bought these a while ago to replace my OEM wiring. Recently I noticed that one of the cables didn't fit and decided it was time to replace it. The cheapest is through Revain. I bought these and replaced four cables - they fit perfectly.

Miata spark plug wires are known to need frequent replacement and for about half the cost of factory wires I can get five years plus life with NGK wires. Of course, a car only covers three or four thousand miles a year, but time is just as important as the number of miles driven.

plug and play replacement for my NA6 Miata. I had low revs, I replaced these leads along with the OEM NGK spark plugs and coil and now it runs like new. We recommend replacing all 3 if you too are having general misfire or low RPM issues.

Standard Miata plug wires fit and work well. Unless you're using some serious boost or something else crazy, you need these wires. Do you know when they were last changed? Just buy a kit and replace them. The ones that came for my 1990 favorite looked good on the outside, but the #3 connector tip/wire was disconnected from the conductor (not good). New set of spark plugs and cables from NGK, it runs much, much better!

NGK cables fit my 96 Mazda Miata perfectly! As mentioned in another review they are numbered for each cylinder so they can be matched to the ignition coil numbers and are basically the exact length needed to reach each cylinder so there is no bunch of loose wires at the top of the head. . Combined with a new AC/Delco coil and NGK Iridium spark plugs, my old lady now works great and the blue wire color gives the engine bay an interesting and clean look.
