Owner reviews for spark plug

When I switched to NGK's it seemed to run better

I just put new plugs in (NGK Iridium IX) and the engine does not shake/miss fire as much as before.

The plug wires do not make a difference. We interchange them all the time here at work (I work at a dealership as well) if need be and there are no adverse effects. All they do is carry the electricity. The plugs on the other hand, that could cause a problem.

i cant comment on the 24v specs, but the OEM 12v plug outperforms everything else i've tried.

I run the BKR7E in all my cars, basically not iridium version of the ones listed here. I prefer copper plugs over iridium or platinum since they are much cheaper.. under 5 bucks for 4. Change them more often then with the others but then you always have fresh plugs.

Just installed some NGK's over the weekend. Definitely idles smoother and quieter. Also feels a bit more responsive to throttle input. Even my wife commented that it felt different and better, which is a miracle. Great $35 mod.

I just took your guys advice and installed the NGK BKR7EIX plugs on my VW GTI 2.0T and I can feel a big difference as far as smooth acceleration and more response! I would defenitely reccomend these plugs to anyone with mods or a chip on their 2.0T!

I have a full obd1 wiring harness from box out 1 brand new plugs(bosh)wires(bremi) cap&rotor(bosh) bucking is not as bad

I changed over to the BKR7E model to see how they worked. I wasn't impressed because after that the RPMs on my tach wouldn't stay steady at idle.

I changed the plugs thinking that what it was. (it was not). I thought it was the coil packs so I bought a new set of four, which I have NOT installed yet.
