Excellent spark plug. - Spark Plugs

If you have a Harbor Freight 3500 Inverter Model, buy it! It's amazing how much this has helped keep the generator running smoothly.

Fits Predator 3500 Generator

Bought for my Predator 3500 Generator Upgrade for the included cheap torch connector. It turned out - yes. I don't know if it's better.

Pros
  • Satisfied so far
Cons
  • Upgradeable

Fits Generator Predator 3500.

Put this in my Generator Predator 3500. Definitely starts and runs better than the plug that comes with it. I don't have to worry about the quality of NGK.

Pros
  • Good price
Cons
  • Not bad

back to platinum

excellent fork. Not cheap. will probably go back and go with a platinum connector. I use them on a motorcycle and they are natorius for overclocking and breaking down. They did, but it took a lot longer between changes. similar results with platinum, but about half the price.

Pros
  • Everything is fine!
Cons
  • no performance

it faltered slightly and seemed to run a bit unsteadily

Order my second set for my VStar. I ordered the first set about 2 years ago. At that point, my bike ran away. it stalls easily and seemed to work a little rough. I thought it might be a spark but everyone including my mechanic seemed to think it was carbs so I spent money getting them and some other work done and the bike ran fine we even looked at each other checked the spark plugs and they looked normal and were properly spaced. After 2 years I finally decided it was time to change the spark…

Pros
  • delivery was very fast
Cons
  • damaged

Superior forks compared to standard forks.

I bought these spark plugs on the recommendation of another Yamaha Virago XV 1100 owner. After installing them I noticed that the bike started faster than before. After warming up, the bike idled smoother than with stock spark plugs. We had a warm day recently so I decided to take the bike and when I twisted the throttle to get up to the recommended speed I was pleasantly surprised at the response. Gone is the slight lag in throttle response I experienced with the stock plugs. The increase in…

Pros
  • Durable finish
Cons
  • Crumpled packaging

Great product but Revain needs an overhaul

I was surprised to find NGK BPR7EIX Iridium spark plugs on Revain.com. Who knew Revane transported car parts? I use these spark plugs in my 2003 Mitsubishi Lancer Evolution and have found that they really make a difference in performance. I tried a non-iridium version of the NGK spark plugs (read "cheaper") and after a few days I had idle problems and decreased gas mileage. I went back to Iridium and haven't had any issues since. The only problem I have is the listing and description of this…

Pros
  • Excellent construction
Cons
  • Nothing here
