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.

Excelente Calidad
Excelente producto, lo e probado por poco mas de un año hasta ahora y sin queja alguna, pero lo que no me gusto fue el embalaje, un total desastre como se muestra en la imagen, no tengo ni la mas minima idea de quien fue la culpa: si del suplidor o del currier. por esa razon hasta ahora no di mi opinion para ver si el producto tenia algun defecto.

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.

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.
