Spark plug NGK or Autolite

I had 2 spare, new spark plugs and these got rid of the misfires in cyls 2 and 4.

I ***always*** use NGK spark plugs after I tried a set of Champion plugs in my old GT380, and two of them failed after 1,500 miles. NGKs have never let me down in 35+ years of riding.

Just use NGK and put them in dry, never had a problem.

Checked spark plugs. The plug is an NGK BP6ES for those that might want to know. This is #4 plug, other 3 in similar condition. Would seem to indicate over fueling, or misfire condition across all 4 cylinders...

Most of my guys like to go with NGK plugs

That’s hilarious I just swapped the exact same plugs this morning in my Lotus, cheapies for iridium, what a difference.

The new NGK spark plugs do not need anti-seize per NGK. The anti-seize is already in the metal.

I've been pulling my CR8EIX iridium plugs out to check how they are burning a lot recently. I've been seeing some light ash deposits and high speed glazing and the iridium tips of the plugs are not as hot as I would expect them to be, i.e., they are not *white*.

after putting the new ones i changed all the spark plugs too, to fit them properly with new wires. but the car runned roughly, so bad..and when mechanic unscrew the new spark plugs to see, they were carbonized black, with just a ride around.

I unknowingly sourced (6) NGK ILZKR7A Spark Plugs a year ago from eBay and installed them at 60K miles on my 3.6 VR6. I found out last week that the plugs were fakes. About a month ago I started getting random misfires. After detailing the issue in this thread here: https://forums.vwvortex.com/showthr...VR6-Cyl-2-Misfire-When-Taking-Off-Quick-From-Stop-Suggestions&highlight=Misfire I pulled the spark plugs and checked them last month and noted the gap was pretty far out of spec (weird for only being a year in), so I gapped them and reinstalled and the problem went a way for a few weeks. Last week I had another misfire, so I chalked it up to a bad batch of spark plugs and resigned to buy and install a new set.
