Spark plug Bosch or NGK

Go to Parker Performance. Look at the NGK Ruthenium’s.

I always had issues when I used any plugs other than Bosch Iridium or Platinum. You can even try Bosch copper plugs if you find the right heat and size. They're usually cheaper and better, but don't last very long... like 10k miles.

So the new set of plugs arrived, so switched out them along with new wires, since two broke during work (Magneti Marelli) and since I already tested and bought a new coil pack basically the whole ignition system's now revamped.

So far after more than two hours of driving, no problems, but Im really careful since I dont wan to find out Im wrong, but it feels ok.

The old plugs where NGK, and after pulling them, their resistance measured on average about 4 kohms.

I kept the previous set, which where Beru's and they measured ~1.4 kohms.

The new set is Bosch, and Im going to stay away from NGKs since I drive a little bit sporty, lasted less than two years, and (I think) 20'000 km.

Yes, they only sell genuine NGK.

Oem oem oem oem dont fuck up your car cheaping out on parts. Especially VQs they don’t perform well or usually don’t even work with aftermarket parts like those considering your plugs or coils. Got with ngk iridium or denso

I have a MK6 GTI and I replaced the Spark Plugs using the NGK recommended ones from Rock Auto and they were the OEM replacements.

I have the projected NGKs and they work great.

I changed spark plugs to NGK laser platinum plugs with a 0.32 gap. The issue only arouse after I got the tune.

the plugs are brand new Bosch Double Platinum.... so then I went out, put them back in and was still a biotch to start....

I did not have good experiences with Bosch on another vehicle.
