NGK(2647) PFR5G-11 Laser Platinum Spark Plug, Pack of 1

These are one of the best spark plugs available on the market today.I was very pleased with them although the car has now been sold.

These are the exact same plugs that came with your Nissan car when it was new. They will easily last 100,000 miles or more. I pulled mine out at 100,090 miles and they looked fine actually. So I have confidence these new ones will easily last for another 100,000 miles. Do NOT put anything else in your car, you will regret it if you do because every single guy I know who tried something else always says "wish I had put the OEM double platinum plugs in!"

These plugs fit well in my 2003 nissan frontier 4cyl XE King Cab. The entire install, which included adding new plugs (I went with the blue set, the NGK 52002 NX101 wires for a recommended fit) took a little less than an hour. Mileage has increased from around 21-22 to 23-24 with peaks in the mid 24's. I have been using them for about 5 months now.

Exactly what I needed, and cheapest I could find.I have a 2001 Nissan Xterra, these are OEM spark plugs. These were the original spark plugs that came in my vehicle, and 160K miles later, I am changing them for the first time. Never lost MPG or power, I had one spark plug misfire so I decided to switch them all.

I now understand why replacing the plugs in my wife's Mazda MPV was going to cost so much at the shop. It's quite a procedure getting to the back three plugs. Luckily I had figured that out BEFORE ordering plugs and thus selected these platinum plugs instead of cheaper copper plugs just so I wouldn't have to be going through this process again for about another 75-100K miles (if ever) on her car. That's why these platinum plugs are worth the extra cost. Car runs great after the plug replacement, but that could be just because I'm such a great amateur mechanic (ha!).
