NGK (9160) RC-ZE21 Spark Plug Wire Set

Nice wire set. Easy to install on my 2000 Miata SE and looks good too. Goes nicely with new NGK spark plugs.

Was advertised to fit a Mazda 626 2000 2.0lt, but several of the leads are to short, so the set is useless

The NGK ZE21 Spark Plug Wire Set is a great product. Like all NGK products, it just fits right without having to modify it. The spark plug wire set is made for the 1990 - 1997 Miata and the length of the spark plugs wires is perfect. I like pre-made spark plug wire sets and not the universal type that require the end user to cut the spark plug wires (to size) and then to crimp on a terminal for each spark plug wire. When you purchase the NGK spark plug wires make sure you purchase the "blue" ones which are the premium set and not the standard "black" spark plug wires. The spark plug wires should be changed every 30,000 miles on a Miata to maintain performance. These spark plug wires are exactly what is needed for maximum performance, so don't bother purchasing the so-called "high performance" spark plug wires because you won't get a better spark plug wire for your money.

The airbag light on a 1994 Mazda MX5 MK1 intermittently illuminated. Not ideal if you wish to sell the car, let alone get it through an MOT. I changed the spark plugs, replaced the air filter, and replaced the old(ish) ignition leads with these RC-ZE21's. Success! Turn ignition to on, airbag warning illuminates (as it should) and remains OFF. The vehicle starts faster, feels better & hopefully will sell!

Works like a charm, easy install. It's authentic NGK and so far works great on my NB miata. Will update if there's anything but I don't have any doubts of the product.
