          I recently bought a 2000 Chevrolet Blazer and it didn't have any take off power at all. I replaced the previous ones with these NGK's and noticed a serious amount of power. I will buy these again and again.

          I've used these in my two LS1 camaro's for several years. They run better, smoother, than any other plug I've tried.

            I recently purchased a few routine replacement parts for my truck to maximize my fuel efficiency, and get the most power I can out of it. Advance Auto parts made finding these parts quick and easy and offered to ship all items right to my front door for FREE. All items were exact fit replacement parts and easy to install. I would easily reccommend to all my friends and family to do the same thing I just did. In fact, next year, I will repeat my process and feel confident that it will be just as easy and rewarding as it was this time. Thanks

              I installed a set of NGK V-Power sparkplugs in my 1996 GMC Suburban (5.7L V8, gas). I noticed an immediate improvement in idle smoothness, acceleration, and overall performance. I expect to see increased fuel mileage as well. I would recommend NGK V-Power sparkplugs as a replacement for any OEM sparkplugs. They are a high-quality product at a very economical price.

                        With reference to your inquiry on the NGK V-Power Spark Plug - part# 3951, you would need six spark plugs for your Oldsmobile Cutlass. The front ones you can change by just removing the plug wires and using the proper tool. For the back plugs you have to undo the front motor mounts and pry or pull the motor forward.
