NGK have always made excellent quality spark plugs. I only fitted NGK to all makes and models over 20 years as a mobile mechanic. Never had one fail which says it all. I'm fitting these iridium tipped ones as they will not need to be replaced for at least 40,000 miles. Fit and forget. Definitely recommended.

This is a terrific product and I strongly recommend these plugs to anyone I recently had to fit a new distributor cap and rotor arm to my 1989 Porsche 944 Lux I didn't notice any difference in performance till I installed these Iridium Spark Plugs and the difference was noticed right away So I recommend them whole heartedly
