            Good

            For the low cost of this spark plug from NGK, this is a great solution if you need a spark plug.

            spark plug

            I would recommend this spark plug to anyone. It has made a world of a difference in my jeep, performance and gas alone was so worth this.

            Great value

            Going from almost burnt out spark plugs to to new ones made such a difference in how it runs and starts, and for the price you pay you're getting great quality plugs.

            new plugs

            smoothed the motor right out, old plugs a little toasted.

            Fix'd my rough idle

            I was running Autolite spark plugs and had rough idle with them, now i put in these NGKs and jeep runs like new again.

            Starts way Better

            I don't think my old spark plugs have ever been changed and my Jeep has almost 150k miles on it. The new plugs have dramatically changed how it starts. Before it always started but it kinda struggled. Now it springs to life with ease.

            Great power

            Just what my ruby needed. My old ones were shot. Very pleased with them.

            These plugs are excellent, you will notice crisper throttle response and a smoother idle.

            NGK V-Power spark plugs

            Installed these in my 2001 TJ. Jeep runs great! At less than $2 apiece, you can't get a better plug for the money. Highly recommended

            Pre-Gapped

            The plugs were pre-gapped. No surprises going in. The old plugs were pretty worn so there is a noticeable increase in power. I'll buy them again 50,000 miles from now.

            Sparks plugs

            With about 157k miles on my 2002 tj I figured it was probably about time for some spark plugs. Liked the price, the products got to me quickly. The install was very easy now running and idling much smoother. Very satisfied
