Review Image by Gary Markwardt Gary Markwardt
I can not believe I was able to purchase a set of quality NGK plugs shipped for less than $4. Amazing. Using these in a 2005 Mazda6 2.3l. It's a quality plug but will need to be changed sooner than oem in this application. Not a big deal as they are easily accessible in this vehicle. If these come back in stock for the price I'll buy another set. ... show more
