NGK(9029) DILKAR6A-11 Laser Iridium Spark Plug, Pack of 1

Good spark plug for Nissan’s. I’ve had better luck with the NGK iridium plug then other brands for my Nissan Altima and rogue.

If you order this also order a SparkPlug Gapper, I used the one from CTA Tools. Once I got them I figured that all 4 NGK SparkPlugs were between 0.22 and 0.34 mm. They should be 0.44.It is EXTREMELY IMPORTANT that the Gap in a spark plug is exactly as the maker intended. For the Nissan QR25de it is 0.44. If you install a spark plug with a wrong GAP in it, although it is new, you could start experiencing issues, a higher MPG consumption and depending on how off the GAP is even missfiers.Other than that, they seem legit NGK brand SparkPlugs.

Same spark plugs that were in my 2010 Altima. Replaced all four at 85k miles for preventative maintenance, and I got a rough idle. Changed each of the new plugs out for the old plugs one at a time, and it turned out one of the new plugs was bad. The gap was good (~0.043; apparently a bad connection inside the housing or something). Anyway Amazon being good like they are; I sent the bad one back, and a new, working one was delivered in a few days at no charge. So I can't knock the product much, but since I got a defective plug: -1 star. I'm sure most other users will have a 5-star experience.

Work great, same exact part as original plugs, should be good for another 100,000 miles. The original plugs with over 100k were in good shape when I took them out. I probably could have continued using them for a while longer, but I didn't want to risk damaging the O2 sensors, and cats. It's not like you can see when they go out of spec. The cost of replacing the O2's and cats isn't worth the couple of dollars you would save by keeping them in for even 40k past the recommended interval. Either way you still end up changing the plugs.

I decided to order the NGL (9029) DILKAR6A-11 Laser Iridium Spark plugs after I reviewed a YouTube video of how to replace spark plugs for my 2010 Nissan Altima. The young man highly recommended this particular one, because it lasts 100,000 miles. The price is a little more than others, but it’s worth it. I received the order quickly and replaced the plugs with the help of my brother. The spark plugs are working great. Prior to the installation, my car would jerk and now it’s running smooth. I will keep you posted!
