Very Expensive
Had one cylinder misfiring so replaced coil and spark plug. Runs fine now, but old plug looked shot after only 5 months so I think the coil was the problem. Really good plug so far but very expensive.

A reliable set of spark plugs.
They’re made in Germany, what else can you say

Work as well as the NGK's
Bought for a 2016 Mazda 6, I had NGK's in it for 5 months and had misfires, didnt have the money to throw more NGK's at it for troubleshooting. Bought these to try and they work great so far.

Faulty plug? Otherwise great set
Definitely better than the old plugs that probably had 80k miles on them.
The one star off is because I had a misfire after installing. Not sure if I damaged the plug or what, but a reinstall didn't fix the misfire. In my genius, I rushed to try to gap it and ended up breaking the iridium tip. Put the old plug into cylinder 3 (where the misfire was) and it was fine.
Gonna have to get a new single tomorrow at my local shop, but a bit frustrating to get a misfire after install.

Upgrade from OEM
After seeing a quite ludicrous $403 quote to change 4 spark plugs in a Mazda3 I decided to show my son how easy it is.
These were an upgrade from OEM parts. They were gapped perfectly for the car.
They took 20mins to fit and work fine.
