Review on 🔌 NGK (8660) RC-XX89 High-Performance Spark Plug Wire Set by Eric Nelso

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 the spark plug hole, which is not disturbing. The edge of these seem to make a great seal and they hold securely in place. All in all everything is done, new spark plugs, a short K&N intake and a simple universal Magnaflow exhaust, the car is not fast but much faster, the throttle response is almost sporty, all for less than £500. I'm not a racer but I appreciate the new ability to quickly pass cars on the freeway, speeds of 70-80mph are much quicker and overall acceleration is vastly improved.
