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.

  • Q:

    Hi,
    I am going to change one side (3) plugs on our 1998 Ford Taurus LX. I am wheelchair bound and can reach the 3 plugs on one side. It costs over $300 to have a mechanic do a tune-up. This is because the 3 plugs on the other side require the motor mounts to be removed and the engine to be tilted to replace those plugs. Crazy isn't it! I have verified this to be true by calling different shops for a tune-up quote. (I am also poor being paralyzed and very little income). The car ('98 Ford Taurus) has a very small miss and this brings me to my question.
    Will putting in higher performance spark plugs like these on one side of the engine cause an imbalance and stress on the motor? Or is it no problem? Or... should I go with the OEM's to be safe? PLEASE answer with certainty and knowledge. I cannot afford a mistake here. Thank you and God bless.

    Sincerely,
    Doug Woodard

      Changing half the plugs won't cause any damage short term. But personally,
      I wouldn't use high performance plugs unless you could change all 6. If
      there is a bad plug causing the ignition problem, a standard plug will fix
      that. If you are lucky, it will be one of the plugs you can reach. Be sure
      to change your PCV valve too.

    • A:

      Only changing one side will not benefit you very much depending on how many miles are on the plugs you have. It cause an imbalance due to lack of spark to ignite the gas and oxygen under compression. The plugs can be changed without removing the motor mounts. But removing them will make it easier. Hopefully someone with a good heart will step up and help you out.

  • Q:

    My owners manual calls for a Denso spark plug, part number; PTZ16R15. While I have no doubt your listing PT16TT will "exact fit", how can you prove to me this is the correct spark plug. I really only want to do this job once.

      02 has to be gapped to .06, I know this thread is old but the only year that needs to be gapped to .06 is 02 unless it is an iridium plug then it stays at .04 but that only applies to iridium plugs.

  • 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)

      Hi Rich, this Denso PT16TT Platinum TT Spark Plug - part# 4511 is an exact fit for your 1999 Lincoln Town Car and is pre gapped at 0.040". However, it is better to stick with the factory recommendations and gap them at 0.054". The plug reach would not make much difference.
