Anyone have any experience with these? I notice they are one of our sponsers, but I have gotten a lot of mixed info when I did a search on them. Some guys are claiming huge mileage increases?!

 

there was a thread about them a few years back, use search function, I think the consensus was they save gas in small engines like weed eaters and lawn mowers but no saving in vehicles.

 

I have a 2003 and have run them for over 10,000 miles. I think they work well. No gas mileage change I have seen. Their claim is better emissions/burn. I bought them from Summit racing. Money back guarantee if you dont like them. So far I am happy.

 

I bought them and had to take them out, at a hot idle the fuel would ignite before the spark plug actually sparked because the ground electrode is so big.
I have them in my wifes Volvo with a turbo and the car likes them, I also have one in my Toro 2-stroke snowblower for over 5 yrs now and she still runs great and cannot be flooded out.
Same with my Snapper walk behind lawnmower, 5+ years with the same plug and you cannot flood it out.
Chainsaw too, used to get ~15 min of hard cutting time, now I give out before the gas does, I can now go ~25 min before she runs out of gas.
In the weedwacker I just have a cheap plug in it because I have to flood it to shut it off because it is old and I have the throttle wired wide open and the on/off switch does not work either.

In my opinion which in no way constitutes a real answer or is meant to be taken for any kind of advice or recommendation by you are anyone on the internet in the whole wide world, past, present or future or even in the event of my death shall it be taken as such...use whatever spark plug you want.
