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.

        Comments about Denso PT16TT Platinum TT Spark Plug:

        I just replaced the factory irridium plugs in my 2004 silverado z71 with these platinum plugs. The truck has 130,000 miles and was starting to run rough with poor fuel milage. These plugs were cheap but after installing them, the engine idles better. Don't know if milage will improve or not as I just put them in yesterday. Also my plug wires were in really bad shape so I suspect that most of the rough idle conditiion was due to the old plug wires.

            Comments about Denso PT16TT Platinum TT Spark Plug:

            Denso is a new brand for me and will be being used in an 08 Montana. Fired well right from the beginning.Today it is -5 F degrees here and I didn't notice any lack of performance. It appears that for northern winters,you can't beat the combination of synthetic oil and Denso spark plugs.I am presently restoring a 2001 Dodge Durango SLT and Denso will definitely be going into that vehicle. I have four vehicles and the next time I get close to needing spark plugs for one of them I will definitely be adding Denso to my AAP shopping list.

              Decided to replace my spark plugs since the car was not running the best and I had just bought the car and did not know when they were last changed. These made a huge difference and its been running good ever since but its only been 15K and am not sure how long they should last. Also these were bought for a cadillac and those engines are picky on what kind of plug you put in them.

                Replaced my OEM with another brand of plugs and felt the difference right away in power loss but after searching and only finding the denzos which is what I believe came original in my truck, in Advanced Autoparts I bought two sets one for my truck and another for my Tahoe and instantly felt the gain in power.

                    I used these spark plugs in my 2004 Ford Ranger Pick Up Truck. I began losing gas mileage and decided to change the fuel filter, spark plugs, air filter, and the spark plug wires. After changing all of these things, the truck runs great and is getting better mileage again. The spark plugs were easy to install. They give my truck good performace and plenty of power. They were pre-gapped and made them even easier to install. I would buy them again and would definitely recommend them to my friends and family.

                    • 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)
