Product Details

The NGK 4390 (RC-FX55) spark plug wire set, also called an ignition wire set or plug wire kit, carries high-voltage current from the ignition coil or distributor to the spark plugs. It is built to OE tolerances and helps keep spark delivery steady and engine performance consistent.

Key Features:

  • 7mm magnetic core construction: ultra-low resistance, wire-wound ignition cable with OEM-specified or better spark plug and distributor boots
  • Variable pitch winding: gives strong EMI/RFI noise suppression and a powerful spark
  • High-temperature silicone jacket: resists underhood temperatures up to 250°C (482°F), plus moisture, oil, fuel and cracking
  • Reinforced insulation: high-density fiberglass braiding over an EPDM/silicone inner layer for dielectric strength and cable tensile strength
  • Stainless steel terminal ends: positive-locking and corrosion-resistant, for a tight fit and resistance to vibration and separation
  • Silicone seal at the spark plug boot: helps keep moisture out
  • Easy installation: wires are numbered for cylinder identification, and coil wires are color coded

NGK is an ignition specialist with more than 80 years of automotive experience. Its replacement ignition products are made to meet OE standards for durability and performance. Cross-reference: NGK RC-FX55.

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

Quick order processing. Excellent customer service when calling to inquire the status of the order.

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.
