Description of πŸ”Œ NGK (8660) RC-XX89 High-Performance Spark Plug Wire Set

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.

High-temp (250Β°+ C / 482Β°+ F) silicone outer jacket resists moisture, oil/petrol and cracking due to temperature extremes.

Cool Plug wires in wires

I use them in a tropical place with high temperature and humidity and they work fine. I recommend them as they are well cut and fit perfectly.

Pros
  • Top marks for hold and durability from testers
Cons
  • There are more interesting options.

Excellent quality good for wires

My OEM spark plug wires were wearing out and obviously had arcing issues. The NGK kit solved these problems. I've had it for a while and the wires look great. Great quality, worth the extra money.

Pros
  • One year trial
Cons
  • Minor issues

Cylinder #1 wire 5 inches shorter

Liked wires for cylinders 2-4. Cylinder #1 wire was 5 inches shorter. VERY disappointed as I wanted to tune the whole machine. On the plus side, the part that connects to the spark plug protrudes a bit and is stiff, which helps keep the wires clear of heat shields etc. If only one wire was long enough. Installed on a 1998 Hyundai Accent 1.5L hatchback.

Pros
  • Good
Cons
  • Almost OK

Just unbelievable! good for cable

I fitted this kit to my Hyundai Coupe 2005 1.6 CC after 156,000 km with the standard kit. Equipped with the NGK Iridium IX kit, fits great as an OEM and even looks a lot better! The vibrations are gone, the engine sounds like a sleeping cat, very, very, very smooth acceleration and a noticeable improvement in fuel consumption, surprisingly stable acceleration at high speeds. The improvements are really noticeable. Definitely a great upgrade and investment, especially over the long term

Pros
  • New
Cons
  • Hard to tell

Quality finish, I like the blue color

Easy to install on a 2005 Hyundai Accent. Wanted to clean it up as warranty just expired, paired them with ngk iridium spark plugs and they work perfectly together. Put all the spark plugs in and everything worked fine just make sure they are all the way in. I've noticed that anyone who has changed my spark plugs before (at any garage) used too much force to insert the OEM wire and deformed 2 of them. Gaskets, nothing seems to be damaged, but there is a noticeable discoloration on the edge of…

Pros
  • Easy to install
Cons
  • I vaguely remember
