Review on 🔌 NGK (55004) RC-FX101 High Performance Spark Plug Wire Set by Tyshawn Adams

Fits 2008 Subaru Legacy 2.5i. I didn't particularly check the resistance/impedance, but I drove about 10,000 km and between these cables and a set of NGK FR5AP-11 spark plugs, the engine began to start and idle more smoothly, noticeably smoother shifts (automatic transmission). stronger acceleration etc. My #4 spark plug was badly worn and causing random misfires and that was maybe the only problem but my car had 198k when I did it and the wires were never changed so I thought they replaced them also during manufacture can replace plugs. Be careful with dielectric grease, although I put a small amount of grease in the housing that connects to the spark plug and everything was fine, but if you put too much on the housing that connects to the ignition coil, you will you have trouble getting it. Plug to stay plugged in. It seems other people had this problem as well, the connector that connects to the ignition coil is deeper than the OEM connector, had to modify the end a little with pliers to fit tightly. Hint: you look really good. I may have to paint the intake manifold to match.
