Description of NGK (8931) RC-FX50 Spark Plug Wire Set: Unparalleled Performance and Precision

Set includes 4 wires (Coil Lead N/R). Variable pitch winding delivers ultra-low resistance, a powerful spark and outstanding EMI/RFI noise suppression. Numbered for easy cylinder identification and coil wires are color coded for correct and easy installation. Positive-locking, corrosion-resistant stainless steel terminal ends for tight fit and maximum resistance to vibration and separation. High-temp (250°+ C / 482°+ F) silicone outer jacket resists moisture, oil/petrol and cracking due to temperature extremes.

Excellent fit for Subaru for Wire

Just the connector kit I will be using on my Subaru now. Recently done gaskets and replaced almost everything while I was at it.

Pros
  • Ignition and Electrical
Cons
  • Damaged

Perfect fit for cables

Perfect fit for my '99 Subaru Outback. These guys are better built than the originals and way better looking. These NGKs are made to last.

Pros
  • Performance parts and accessories
Cons
  • Hard to tell

Well-made, high-quality spark plug cables

These are quality wires made specifically for a specific application. I didn't feel like the manufacturer only got universal wires that were close to the right length. Each cylinder is labeled and the straight and angled fittings were stock like the OEM.

Pros
  • cable
Cons
  • There are other interesting options.

For 1999 Subaru Outback 2.5

For 1999 Subaru Outback 2.5 engine. This is the one you want, not 8691, plug shoes are very different. Made a huge difference in acceleration, idol and throttle response. Very nice set of well-made connector wires. I checked the resistance and they were all the same at 6 ohms.

Pros
  • Spark plugs and wires
Cons
  • Ugly packaging

Does not work - engine side wire does not fit over spark plug head

Does not work despite claiming compatibility with my vehicle. The wire on the engine side did not match the spark plug head. standard size spark plugs; how do you make a cable so bad? Was able to return and eventually received a full refund.

Pros
  • Wire Kits
Cons
  • Wires shorter than other kits
