Plugs are great quality of course but be aware, the caps do not come off. I need to order NEC plug caps to match.

There's absolutely nothing wrong with these plugs. They are however mislabeled. These are resistor type plugs but the product description and label is for non resistor plugs. And for those critics that are keen to criticize by saying.... "yes but the picture clearly shows an R on the insulator".... I'm very much aware of that. The product however was labeled as non resistor from the vendor.

たかがプラグだと思って古いプラグを何気なく使っていましたが新品に変えた途端調子良くエンジンも当たり前に一発始動当たり前だけど最高品質

After only 30 hours my predator 3500 ultra quiet generator from harbor freight was not starting easily anymore. I run ethonal free pure gasoline so it wasn't bad gas. I took a look at the spark plugs and it was more carbonized than I think it should be at 30 hours since their service interval is 100 hours for a replacement spark plug. I am biased, I do like NGK but I installed this and generator started immediately. I put a lil anti-seize on the threads and torqued to about 30-35 ft lbs and the thing fired right up and idled great. I'm not saying this plug makes it into an instant hot rod or generates more ponies or more wattage. Rather, its a adequate and possibly better than OEM harbor freight plug. Generator puffed a decent amount of black smoke at startup and again when throttles up under load. With the new plug, it's less smoke than before and it's mostly grey not black.So there you go...

I tried out these new spark plugs in my Jet Ski this weekend and there was a noticeable improvement over the Champion brand that I replaced. Much better acceleration and less plug fouling. Priced good and works well.
