NGK (55004) RC-FX101 Spark Plug Wire Set

For Subaru, they wires are super easy to install. Each cable is numbered and lengths are perfect for running along the OEM provided tracks/hooks. Excellent quality, tight fitting rubber boots on each end. Silicone dielectric grease is provided, too. Wires feel chunky and substantial. After installation, the engine ran much smoother. The factory cables were not assembled as well and would leak sparks.

These fit my Subaru perfectly and I had no problems installing. They have performed beautifully. The blue color is a bit striking when you open the hood, but car tuners will probably like that. I've always had great luck with NGK and these wires are no exception.

Easy install, Great quality

These wires work great and don't pop off like the aftermarket ones from autozone. Great price as well

Had bought a set of duralast wires and plugs one and three kept slipping off. Bought a set of NGK wires no more hassle of that or miss.

My Subaru (2008 Outback 2.5i, 4 cyl non-turbo) was getting a misfire on cylinder 4. Last time I had misfires 40k miles ago I replaced the wires with a ProStart set (already replaced the plugs 10k miles before) and that cleared up the problem. After replacing the wires (and plugs) this time with another ProStart set I was getting misfires on 2 & 4. Thinking the ignition coil was bad I installed a new one. The problem still persisted but luckily I bought this set of wires when I ordered the coil. I swapped out the new ProStarts for the NGK FX101s and now it's running great.As you can see from the pictures, the NGK set is blue. I don't really care what colors are under my hood (okay, maybe not pink) but they do look nice and match my blue car. The cables were each numbered which was also nice. The quality is excellent and they attached securely to the spark plugs so there should be no issue there. In contrast, the ProStarts didn't have a tight fit, especially on 2 & 4 where I had the misfires. They were too easy to pull back off.I hesitated at first to buy these because Amazon said it did not fit my car. I had to double check with other sites. When I look now it does say it fits. For now on I'm going to stick with NGK plugs (bought G-Power 7090) and wires for our Subarus.

Compared to original equipment the metal, cylindrical contacts were shorter. They seemed to work, but had us worried. If they had not been specific to our Subaru Forester, I would have returned them. They are working fine.

They were an exact replacement for the original spark plug wires. At 202,000 miles I was getting a cylinder 3 misfire code. I replaced the plugs, and that seemed to fix the problem, but a two months later the misfire returned. My best guess was that the 17 year old plug wires were well past their prime. The price was good, and they arrived in two days. Installation was easy, and I had no problems making the connections at either the coil or the plugs. There was an immediately noticeable improvement. I’ve only driven it 20 miles, but so far, so good. Time will tell.
