About this item

  • DENSOs revolutionary Twin-Tip design is a combination of highly durable precious metals-Platinum and Titanium.
  • The center electrode is created using an extremely durable platinum alloy that allows for the reduction of the tip size to 1.1mm in diameter, while maintaining the life of the plug.
  • The Titanium-enhanced alloy on the ground electrode also increases durability, which is critical to minimize tip erosion and achieve the new Twin-Tip design
  • Superior ignitability of the DENSO Platinum TT means more efficient combustion, which yields better engine performance in terms of power and fuel economy.

Good plugs. Check the gap
4 out of 5 stars
Good plugs. Check the gap
These were ordered as presumed 4.0 gap but came as 3.2 . Always check your gap with the sticker under your hood (second picture) before installing these. Otherwise works well for the cost

    Prior set were NGK Iridiums and they were burnt out. I was shocked I wasn't receiving more shudder in acceleration. I double checked the Denso website for application accuracy and these matched. Great pricing, preset was on point. I've got 2 additional as spares as my vehicle is a four cylinder.

    I have bought these twice for my dodge ram 1500. They perform great, they're high quality, and lasts a long time. The first set lasted over 3 yrs. I had them checked once a year during routine maintenance and were good for 3 years. I still could have used them but were fouled and decided to replace them. They seem to help with performance and gas mileage which is a bonus. These are my favorite brand. Seller ships promptly and are gapped to spec. Highly recommended these.

    I'm only giving 4 stars but really deserves 5 star but because the person who told me to order them and they will do the work well they did the work which I am very happy with but once they took care of the ones that need to be replace they didn't go any further then what had to be done, which I am truly grateful. I thought I was going to have to buy another car and I didn't want to do that at that time. After they replace the bad ones it ran like a new car. I no longer had to worry about coming to a red light any cause it no longer spits and putter at a stop. I no longer have put it in neutral to prevent it from dying and car behind me no longer had to wait for me to snap out la la land so I could put in drive and give give it gas so I could take off. Or not give it too much gas at one time causing it to die. This really help Ed my car performance.

    I've used Denso spark plugs since 1976 with my first car, Datsun 510. Fast forward almost 50 years and about a dozen different cars, I've looked to Denso spark plugs for many of them.

    This time for my 2003 Toyota Highlander V6 with 180k miles and now on its 3rd set of Denso spark plugs.

    Top quality, fit as intended, and never had a failure. Recommended for a good basic spark plug.
