Premium Performance Upgrade: 6 New NGK Iridium IX Spark Plugs LFR5AIX-11 # 4469 Review

I love them. My second sentence. The first installation was 100,000 km ago. The old set worked perfectly, it was only necessary to refresh the engine with new ones. The old kit looked great after 100,000km.

Comparing the quality to the dual platinum connectors I replaced in my 2012 Ram 1500 5.7L Hemi it was easy to say I made a good choice have these iridium candles. Once the install was complete, my ram started faster, ran smoother, and accelerated faster. I haven't heard anything about the mileage.

Installed on a 2006 Nissan Pathfinder 4.0 V6 with 135,000 miles, spark plugs fit perfectly. After 15,000 miles I'm running like a champ. We'll see how well they hold up in Vegas this summer. I think some customers got real NGKs and some fake ones. I avoid online now for these articles. There is a real bargain at the local dealership but it will cost you and I agree.

I installed 6 of these on my 2008 Nissan Quest after accidentally causing a misfire problem (water splashing on the spark plug area). Anyway I replaced all 6 because my code said P0300 which means random misfires. And I don't have time to guess, and I don't have any fancy spark plug testing tools. Anyway, all 6 were replaced and I've had the problem ever since (about 3 months I think). For the price I can highly recommend them. I decided not to rip them apart because a mechanic friend of mine…

When I found mine I thought it was a really good price. When I get them I install them, they claim it's a pretty big .044 gap. After installing them I noticed my car was acting strangely so I took the spark plugs back out and checked them with a spark plug tool , whenever I measured it. was 0.034. And my car worked for about 5 minutes and the candles have already burned out. I'm very frustrated with this, I've heard they're supposed to be amazing spark plugs but as far as I can see they don't…

These were recommended candles. All were neatly ironed. Oddly enough, when I changed them out, I noticed that some of the old spark plugs weren't tight enough, which caused some oil to leak out. Clean well before installing new spark plugs. You can also apply some dialect grease around the connector. If your car has 100,000 miles or more and you haven't changed your ignition coils, you should do this when you change your spark plugs since you are already pulling out the coils. Getting to the…
