Review on NGK 4339 Spark Plug by David Strawn

This spark plug worked great on my bike and is better than the factory one. I have a feeling the customer who checked this out and called it misleading knows little about vehicle handling and nowhere in the ad says it's quadruple. Only after adding to the shopping cart is an image added. I have a feeling the previous reviewer was mechanically disinclined to know that 4 spark plugs would only cost a few bucks. If he felt that wrong, he should have filed a formal complaint. Regardless of what I digress, NGK is the best they've done in a while, of course they're the best.
