The plugs are ok, just didn’t get the performance I wanted.

Lawn mower starts much better. No more stalling. Highly recommended over oem Toro plugs.

I installed these spark plugs in my 2008 Harley Davidson Electra Glide Classic. It’s been upgraded to a 106 cubic inch motor. With many high performance parts. Including Ross Hi-Tech Teflon coated convex racing Pistons, S&S gear driven cams, Commander 3 racing commute computer and many other upgrades.These plugs fit perfectly and have the bike running great. Even with all the upgrades these plugs have the bike run perfectly. Just as good as the Harley Davidson spark plugs if not better. That’s the spark plugs that they replaced. I have checked the plugs since I installed them. They are running at the perfect temperature as far as the coloration on the electrodes on the spark plugs. There is no excess build up of carbon or any types of residue on the spark plugs. They seem to be running at the exact perfect temperature range for the bike.The set of Harley-Davidson spark plugs go for a much higher price. These “NGK3932” spark plugs are definitely worth the money in my opinion. I have tried the different types of so called high performance spark plugs. The V-shaped or serpent’s tongue tip electrode type of spark plugs. They seem to burn out prematurely. Also those v-shaped spark plugs at high RPM seem to break down intermittently causing backfires, spitting out of the mufflers and loss of consistent power.

Can’t speak to durability since they just went in. However, NGK makes good plugs that I’ve used in other applications with good success. Much better price than the HD dealer.
