NGK (1675) PFR7S8EG Spark Plug - Pack of 4

So, there are some really good fakes out there. There are ways to determine if what you get is legit or not. Looking over the boxes, plugs, machining, etc. These are real. A really good way to determine if they are genuine is to take a multimeter and shoot for resistance through the spark plugs. They should have values within 10% of each other. I tested my spark plugs I received and they read anywhere from 1.38-1.44 ohms, well within the threshold of a genuine plug. I wouldn’t hesitate to order from this buyer again and I would still check for knockoffs either way.

I have not installed yet, but after an official authentication process through ngk’s tech support, they did in fact confirm the authenticity

As mentioned gaps can be off on some plugs. I re-gapped them all to .31 and right away could tell the difference in power and shifting. Good plugs. I've seen multiple gaps out there from .28 to .32 for B'7 and decided to go closer to .31 since I'll replace the plugs sooner then later. Last time I used Bosch and I think I prefer NGK. Cold starts were for sure quicker too. If you don't know how to gap a spark plug get a tool, it's simple.

All good. Thank you.

Arrived undamaged. The plug's themselves were packaged well. But the set of 4 came in a small bubble wrap envelope. I guess was good enough although I would have preferred stiffer packaging. But the plug set appeared fine and been operating correctly 1500 plus miles already.
