Review on Champion Spark Plugs REA9WYPB4 Iridium by Scott Rose

I installed Champs. About 1 month ago @ 113,000 miles and my Nissan Frontier 2.5 LP/Up puts a smile back on my face. There are now far fewer downshifts when going up steep hills. I immediately noticed an increase in power and an increase in fuel consumption. Don't listen to "shops" that only fit NGK spark plugs. They charged me 4x what I paid ($80) for my 4 champions ($20) plus 3.5 hours of workshop labor ($400 total). I have used Champion spark plugs in my muscle cars and everyday drivers for decades and they are great. (and no, I don't work for a champion). Only one verified happy buyer. For a little extra oomph, install a K&N filter in your stock cold air intake system. Change your oil/filter every 10,000 miles with a Mobil 1 and Fram filter and your engine should last hundreds of thousands of miles.
