NGK(1675) PFR7S8EG Spark Plug - Pack of 4

Works as intended-be sure to measure the plug gap before install-no fouling or or pinging/knocking (assuming you installed properly and use quality gasoline)-car feels more smooth during acceleration upon install-gas mileage somewhat restored after installation (note: gas mileage depends on many factors)

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

Installed second set of NGK Laser Platinum PFR7S8EG on 2015 Audi allroad (US spec 2.0 TFSI CPMB engine) at 60k miles (37k miles on this last set of plugs). Always use Motul X-Cess 8100 oil and Shell 93 octane gas (with a can of Seafoam, Marvel Mystery Oil, or Starbrite Startron fuel additive from time to time). Car has mostly highway miles. Heat range on side electrode was correct, center electrode color and condition were normal, and there was dry, dark carbon on base ring just over one full turn. Secondly, noticed new replacement set (of exact same plugs) came gapped between .028" and .032" so left them as is. Also noticed old plugs did not feel real tightly seated upon removal (but no blow-by visible on crush washers) so recommend rechecking 22' lbs torque after a few miles/time has passed. Plugs were originally installed dry. Based on observations between the factory installed set of VAG OE plugs (changed at 23k miles) and this last set of NGKs, I am going to change the next set around 30k miles. Love how the car is running, just don't believe the life expectancy claimed for modern plugs based on amount of deposits seen.

No, I didn't expect these to be pre-gapped based on no such claim in any of the product information presented here. However, the opinions of many online forum posters I've read seem to indicate differently.No matter, I was quite surprised that in this box of four, one plug was gapped every so slightly "correct" for my application at about 0.031, while the other three were at or over 0.040.I only mention this here to advised anyone to have their gapping tool at the ready.Otherwise, nothing else noteworthy to say about these plugs. They're replacing the NGKs my dealer put in 40,000 miles ago, per the manufacturer's maintenance recommendations, and those have held up just fine.

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.

Replaced these myself as part of the 35k recommended service on a B8 allroad. Pretty easy to do. I did research on the proper replacement plugs and these were closest to factory recommended. You can take my word for it or do the research yourself. Lots of pages of platinum vs. iridium and NGK vs. Bosch vs. others. I feel that plugs are changed so infrequently that it's just not worth it to mess around with anything new or slightly different than recommended, as any performance difference would be negligible. I didn't have any issues before or after the change so no performance change to speak of nor was any expected.

All good. Thank you.
