Owner reviews for spark plug

I’ve been running NGK Irridium tips for 30,000km and haven’t had any issues

Brisk plugs off Parker performances page. The brisks hold there gap and seem to really last

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.

after changing the spark plug for another autolite it stopped misfiring its still a little rough so I fear it may comeback so I just ordered some NGK plugs.

ditch the delco plugs, they are trash. And delcos are shit plugs.

Never use the Bosch ones for the E46s. Just not working right
