Finally replaced the old OEM plugs that were installed several years ago, though I've only clocked about 35K miles in 6 years. The truck is a '99 S-10, 4 cylinder automatic, daily driver with 118K on the clock and it had been unusually anemic accelerating for awhile. I bought the Denso Platinums as most reviews were positive and the price was right.
I put them in and started it up: WOW, engine's running smoooooooth, quiet, I can hardly notice the drag when the A/C turned on. Now, this is a daily driver, not driven hard since this engine/trans is pretty pedestrian and even moreso with the A/C on, but the Densos have amazed me with the improved performance. Fuel mileage appears to be up too but I need a few more tankfuls before I can quantify this.
Great product, IMO.

I installed these on a 2006 GMC Sierra 5.3L V8 with 117,000 miles. I was getting 16.5mpg mixed. After installing these, I noticed an instant decrease in power, it idled poorly, and my average mileage over 4 weeks has been 14.3mpg. My advice is look elsewhere. Spend the extra money, use a coupon code, and get the AC 41-805 or 962 plugs for $5 each.

      Mine cracked in the engine. These went in without a problem. I put anti-seize compound on these so they could be taken out later for replacement. I also used di-electric grease between this and the coils. So far no problems.

        Did these in combination with new wires and coil - truck is running much better than before. Did the whole job for ~$150, wondering why I didn't get to it sooner.

          It is hard to tell with plugs, but installed four new ones on my Ford Focus, and no problems. Old ones were not in bad condition, so could not really tell if the vehicle was running better or not. They install easily.

            Comments about Denso PT16TT Platinum TT Spark Plug:

            It didnt fit my spark plug socket..
            So I had to stretch the hole of the socket with a small paint brush handle or pen. I then duct tape the socket to the wrench..so the socket doesn't slip off while I'm installing it...and that worked perfectly.
            My first time changing plugs.. I even had to remove the intake manifold to get at the back cylinder of my V6

            The installation was a success and I could feel the difference right away...now my Mazda runs like a hot knife through butter.

            Glad I got these...and will continue to do so.

                  • Q:

                    I have a 1999 Lincoln town car with a 4.6 L. I noticed that the reach is slightly different between your Denso PT16TT (45.11)and your OE Motorcraft (SP 493). (Denso .708 inch) (Motorcraft (.679)inch). Will this make any difference? Also I must change the gap to .054 inch. That means that you have an angle in the lateral electrode to overcome the difference in gap. Does this angle of the lateral electrode make a difference? It looks like from your other posts that the OE recommended gag is preferred? I have always been taught to stick to the OE manufactures recommendations. (under hood sticker)
