NGK American Motors AMX 1980-1978 Spark Plug Wire Set

If you're working on your American Motors AMX from 1978 to 1980, or a range of other vehicles like the Concord, Eagle, or Jeep CJ models, these NGK spark plug wire sets are a solid option for replacing your old, worn-out wires. They're built to deliver a more powerful spark to your plugs, which can help with smoother engine operation and better overall performance.

NGK uses a magnetic core with stainless steel winding to achieve ultra-low resistance. This design helps ensure that the high voltage current gets to the spark plug efficiently, while also suppressing radio interference. The outer jacket is made of high-temperature silicone, and the inner insulation uses a combination of EPDM and silicone for excellent dielectric strength, keeping that high voltage contained. The boots are designed to fit right, with stainless steel terminals that use multiple crimps for a strong connection to the cable, and a locking clip on the spark plug end to keep everything secure.

These wire sets come with OE-specified boots, meaning they're made to match the original equipment fit and function. They're also sealed with silicone to keep moisture out, which is important for reliable ignition. NGK backs these wires with a Limited Lifetime Warranty.
