Spark plug NGK or OEM Toyota

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!

Seeing how the dealer's prices are always higher, I'll be replacing the stock plugs with a set of the NGK's. Ive always run them in my 1.8T, and now my 2.0L 16v... and again... will be picking up some for the 2.0T FSI.

i had bosch and just switched to NGK BKR7EIX. theres a difference!!!

I am planning on ordering a set of NGK BKR7EIX. They are one heat range colder, and I keep hearing good reviews. I also hear the downside is you have to replace them more often. I think if you search for them, you'll find better reviews from ppl who use them and diy if needed. I found them here http://www.sparkplugs.com/resu...&y=17 , might be cheaper elsewhere, I haven't started shopping yet, im just coming up on 10,000 miles.

Mine popped up with the NGK's all i did is tighten the spark plug a little more and it stopped.

I tried those spark plugs and my car had a really bad idle. It shook like crazy then the CEL starting flashing. Some liquid was spitting out of the exhaust and some had some funky smell.
