Reviews of NGK spark plug

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.

So the BKR7EIXs are in and gapped to .028. Man what a difference. Everything is so much smoother and the engine doesn't feel strung out anymore.

For a stock 4.3 you won’t see any performance difference regardless of what you put in there. Cheap copper plugs will work great but your going to be replacing them every 25-30,000 miles, iridium will probably last as long as the rest of the vehicle.

Replace the spark plug with a genuine NGK plug.
