Reviews of NGK parts For Business

i know of several 2.5T and 2.0T (big turbo) running BKR7EIX gapped at 0.028"... Myself included, and no issues.

I am running those in my car now and they are perfect!!

Personally I prefer NGK and have had excellent results on our customer's cars with NGK. They make a great plug.

On almost all FSI / TSI applications we prefer the NGK, either PFR7S (which is the 'oem' plug on most TSI engines we see) or PFR7Q gapped to .028. We have had bad luck with missfires with the Bosch on tuned cars. Stock seems fine.

I honestly can't say if you're low/high or I was low. What I can say is on my 9A 2.0 16v (rough guesstimate 185k miles)... NGK iridium plugs (standard gap)

I was having some stuttering/mis-firing at high boost on the spark plugs so I switched to the NGK BKR7E with a .028 gap. Right away I noticed a huge improvement but I can't help but feel it could be better.

From my own experiences the raceplugs seem to help with misfire happy maps.

Been using the ngk ones for 10K km so far and they work just like oem, no problems, no misfires.

im still running the NGK BKR7E's at a .026 gap with 11 psi, they do foul quickly but I plan to keep changing them every oil change.

I have the one sided electrode NGKs and it screwd up my mileage. but it seemed to happen once I switched the spark plugs.
