## Description

NGK Spark Plug Stock # 6240

Review: OEM Double Platinum Spark Plugs (03 Sentra) - The NGK 6240 or PLFR5A-11 are the OEM plugs for my 03 Nissan Sentra. I ordered 4 of them to replace all my spark plugs and they all arrived in good condition. Each of the plugs had the protective cylindrical cardboard and came in decent packaging. I checked each of the gaps for the plugs they were only slightly off from the OE .044(IN) which I adjusted. If you’re going to do this you want to be extra careful as the platinum can be damaged. I think the best way to check the gap is using a wire gap tool and adjust the gap very carefully. There’s no need to apply anti seize as the threads already have a coating on them and is even stated by NGK not to use anti seize. If you really want to apply anti seize you should reduce the torque you apply by about %20 the manufacturer spec(still don’t recommend it). I also added dielectric grease/silicone paste to the ceramic portion of the plug(bottom white part) to prevent moisture from getting into the coil and to make future removal easier. If you’re going to use dielectric grease/silicone paste you only need a thin layer and avoid getting it on the end of the spark plug(only apply to the ceramic portion). As pictured the OE plugs were a perfect fit to the old plugs but the previous owner cheaped out and used copper spark plugs that fit my car but they shouldn’t have been used for it. Installation was great and the car started up much quicker. Along with that the engine felt much “smoother” especially at high revs compared with the old plugs. This is definitely one of best easy tune ups you can do to a car and get a-lot out of it. TLDR: OEM plugs, great install, smoother engine, and worth every penny.
Review: Great Price, Great Spark Plugs and Original Replacement for Nissan - NGK brand is the Original Replacement of Nissan brand automobile Spark Plugs. I just replaced spark plugs of my 2003 Nissan Maxima SE V6 which has 147.000+ miles on it. Every 75k changing spark plugs are the best time frame. Old ones I pulled out with corrosion on the tips. I have noticed right after changing the spark plugs that; Starts Faster and Smoother Engine Warms Up Quicker Less Noisy No More burned oil smell when I push the gas pedal all the way down on 1st gear Acceleration got back in original timing and Mileage per gallon will be better as well. NOTE: Do not forget to buy Silver Anti Seize for applying on the thread of the new spark plugs and Do not forget to buy transparent Boot Grease which you have to apply on the ceramic portion of the Spark plugs. That way it make it easy to place them on, keeping the coil boots and threads in a good shape, and makes it easy to pull them out when you need to replace them again. Great Spark Plugs, I recommend to use NGK which originally made in Japan. They do provide best out of the box on Nissan.

### ⭐⭐⭐⭐⭐ OEM plugs perfect
*by M***. on November 30, 2019*

My Nissan Titan has 72,000 miles on it. it's an 06 thought it might be a good idea to inspect the original Factory plugs at 14 years old and thought it might be a good idea to replace them. Initial inspection showed slight wear on the factory plugs so it was a good idea. Usually I would not check the gap on plugs of this nature but the way they shipped some of them had came out of the package, so I checked. I'm glad I did they were far off 044 so I re gapped them to that specification. A little never seize on the threads and good to go truck runs fine
