So I was in one of my favorite auto parts stores and looking for spark plugs for my Toyota pickup truck. It’s a 1992 red mini-pickup with the 22RE 2.4 liter, four cylinder engine. They guy at the counter asks me what kind of spark plug I am looking for. I told him that I wanted the best he had. He has a set of E3 spark plugs which he claims are the ultimate spark plug. OK, I’ll give them a try. Less than 6000 miles later I am on the highway and the engine is having high rpm misfires. This is bad. So I pull off and hit another auto parts store.
I pull the spark plugs right there in the parking lot and look what I find. These things are junk. The electrode has so shrouded the spark that deposits are caked on and have raised the resistance so high that the plugs misfire.
I don’t think I’ll be using E3 spark plugs any time soon.
