E3 Spark Plugs

Personally, I have seen tons of instances with the E3 plugs not firing at all or misfiring in small engines (lawn tractors, weedeaters, etc) and just from that refuse to try it in my truck... My dad and I installed Platinum plugs in an older Nissan truck some years ago and got great performance out of them. Just make sure it's a good name brand not some "house" brand...
