Very easy to install if you know what you’re doing. The car drives smoother and has better performance over the old 70k miles ngk plugs. I recommend this product.

Installed it on my 2015 328i and it fits perfectly. Engine misfire goes out and my baby is smooth again

Easy install great spark plugs

DO NOT BUY THESE FOR YOUR BMW. These absolutely do not work in an n55 engine. They were gapped correctly but after installing these I had misfires in every cylinder. All kinds of codes were thrown. BMW recommends .032 for the n55 engine, which is what they are gapped at. That didn't work, so after reading online I saw that .023 works on tuned vehicles. I figured what the hell, and gapped them. The result is the same. Misfires all over the place, codes thrown, and limp mode immediately. I removed them and went back to the stock plugs and amazingly it runs great. Imagine that. Stick with the OEM plugs.

Was hesitant to buy these but I bit the bullet and I went for it and honestly I think they're the best plugs I've ever put in my n54 they are firing hot and working well I have mhd tuner and they seem to be working great with it haven't had no misfire since installing them over 2 months ago yes these are great plugs buy them up don't be a naysayer if they're working good cuz I really believe that there was no good plugs out there unless they were the OEM plug from one plug to another plug these are great plugs and I put my plug rep on that

Put them in and they looked exactly like the NGK ones that came out of my BMW. so far they are running strong. Hopefully they last many years

Perfect fit… I bought a non running X3. It appears that there was very little maintenance done on this car. Old plugs were a bear to remove. These plugs slid right in. Car running excellent. Thank you.
