Review: Quality Spark Plug Wires that Do the Job - These replaced a set of wires that had been on the our 1997 Miata for almost 15 years. I also replaced the plugs. As you would expect, there was an immediate improvement in how the engine ran. I've read complaints about the quality of the connectors. Mine all clicked when they went on, and after a week of driving, the remain tightly on plugs and coil. Visually, they appear to be of very high quality. You can buy cheaper wires, but these appear to be heavy duty and I expect that they will be on the car for some time. Review: Miata plug wires. - If you’ve been in the Miata world you know these are the only wires that last a decent amount of time.

Buy once cry once. ### ⭐⭐⭐⭐⭐ Perfect match! *by W***I on January 19, 2019* Theses NGK wires fit my '96 Mazda Miata perfectly! As stated in another review they are numbered for each cylinder so they can be matched to the ignition coil numbers and basically made to the exact length needed to reach each cylinder so there isn't a bunch of loose plug wires along the top of the head. Coupled with a new AC/Delco ignition coil and NGK Iridium plugs my old girl runs great now plus the blue wire color adds an interesting, clean look to the engine compartment. ## Frequently Bought Together - NGK (9160) RC-ZE21 Spark Plug Wire Set - BOSCH 77103WS Workshop Fuel Filter - Compatible with Select Mazda Miata - 4 pc NGK V-Power Spark Plugs compatible with Mazda Miata 1.6L L4 1990-1993 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/2947715-ngk-9160-rc-ze21-spark-plug-wire-set](https://www.desertcart.pt/products/2947715-ngk-9160-rc-ze21-spark-plug-wire-set) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-07*
