I tried to find another thread on them to no avail. I want to change my plugs soon but I'm not sure which to get. I've heard brisks are good but I haven't heard anything about E3s. Just curious. It's an 08 bolt on GT.

 

I herd avoid the e3 plugs! Over priced and they do not perform. I would go with NGK. Best plug on the market, but thats my option. I've never had a problem with NGK spark plugs!
