NGK Mercury Capri 1994-1991 Spark Plug Wire Set

If you're working on your 1991-1994 Mercury Capri and need to replace the spark plug wires, this set from NGK is a solid option. These wires are built to handle high voltage currents, ensuring a strong spark gets to your engine for reliable performance. They're designed to meet or exceed original equipment specifications, so you can expect a good fit and dependable operation.

NGK uses a stainless steel winding over a ferrite magnetic core to create wires with ultra-low resistance. This design helps deliver a more powerful spark and also suppresses electromagnetic interference, which is good for your car's electronics. The outer jacket is made of high-temperature silicone, and the inner insulation uses EPDM and silicone to keep those high voltage currents contained. The spark plug boots are sealed to the cable with silicone for a watertight connection, and the terminals use a locking clip with corrosion-resistant plating to ensure a secure connection to the spark plugs.
