The quality of this spark plug really stands out, and installation was quick and easy. If you want better performance and fuel savings, this is the spark plug to get.

Male sure you get them in the box pictured
Make sure you get them in the sealed box pictured, box top was sealed shut, I opened it and inspected all four since this is my second order. All were in perfect, untouched appearance. Gaps all uniform, electrodes line up perfectly, gap appears identical in all four, and the firing end protected by cardboard tube. Also, these came in a 6x6x6 heavy made box with a few air pouches...well protected. My first order of four came in an envelope, no outter box like picture, haphazardly just thrown in, all four loose to move around in the envelope, two where actually out of their boxes just tumbling around in the envelope. Two of these four even had been gapped wrong and the electrodes did not even line up. Easy fix these used four are going back to Amazon and should have never been sent out in such shape. Hope the picture and the above that I went though to get four actually new, untouched plugs helps others. Accept nothing but the sealed box, otherwise you're likely getting problematic plugs like I did, send them back.These are excellent plugs, I have used these before and know this first-hand. I feel some if not a lot of the negative reviews come from subpar plugs being shipped and installed, creating running problems. I definitely recommend the properly handled, packaged, and shipped plugs! 💯 Percent.

Good quality plugs
Put these in a Honda Fit so I had to gap them some. The factory gap was really consistent on the set and they were easy to gap out some. Went in no issues and are performing better than the Autolites I replaced them with.

appears to be good product but time will tell
appears to be good product but time will tell. The car installed in (Saab 95) is temperamental with spark plugs. Plugs purchased are top of the line Japanese plugs. They may be good or be bad. Top of the line Bosch plugs were good at the start of use but deteriorated rapidly. Time will tell if Denso are any better. They cost 150% more than Bosch for same specifications.

These are the BEST I've tried!
I have an oil-burning 2009 Audi A4 with 2.0 turbo motor. This is was deemed a bad motor and Audi owners were awarded replacement motor in a class action suit. The piston rings allowed excessive oil blowby. I didn't get mine replaced (missed the cutoff) so had to detail with an oily engine. It was every where and eventually got to the plugs along with carbon deposits. I tried some replacement platinum plugs and they would only last for a couple thousand miles before giving up--engine would struggle to turn over, just kept revving. After going through a couple sets, I opted for the IRIDIUM version and those have been good for 10k miles! If you've got an oil-burning turbo, give these a shot. They keep firing even after all the crap thrown at it from direct-injection "advancements." Outside of a rebuild, this is the best bet for keeping your car on the road.

Run Great in My BMW
Excellent results so far. This was my first experience with this particular spark plug, and I really wanted a suitable replacement for the Bosch +4s the car came with originally. Which I was never a fan of, and I am also not impressed with NGKs most people use due to issues in anothe vehicle. Double check the gap, and of course, always replace the coil boots. I am happy to say my car is running great. She seems a bit smoother, and my performance and mileage is restored to where it should be. No issues on the scanner and all the monitors are exactly where they should be. I was not expecting any issues so I'm really not surprised. I do expect these Densos to last longer than the OEMs they replaced. I might amend this depending on long term performance. A bit of background, I am an ASE double master, and these went into a 1999 BMW 540i.
