The Best
I've been strictly a Denso user for many yrs. These TTs work much better then the compatable NGKs in my humble opinion. I used these to replace 100k plugs that came in the car from the factory, and she runs better then when she was new. Amazing spark plugs, and a great deal, since my car uses 12 plugs.Read full review...

Buy them
Spend the extra money, put them in and never have to go through this awful chore again.
My 2007 Ram 1500 4.7 V8 was overdue for spark plugs, and I was right when I guessed they were factory OEM, but I was shocked Dodge stocked them with the cheap grade Champions. At 117k miles and pulling a camper, I knew it was not running at peak. I am glad I got the best plugs I could get because l am sore and cut up today but the truck runs great.Read full review...

Great Plugs
Tried the TT plugs for the first time in my 2006 Scion XB over the standard iridium plugs. I immediately noticed improved throttle response, and might I say increased power? My average fuel mileage went from 30 to 32 mpg. I felt that they made a significant difference, so I am going to try them out in my other Toyotas. After 64k on the regular iridium plugs, I look forward to seeing how long these will last.Read full review...

What an amazing change
My scion with 140k has never run so smoothly. I installed these a few weeks ago and I am still marveling. Previous plugs were denso iridium with 50k on them.

Great plug
Can’t tell engine is running! Feels like the plugs have made car more responsive with just a touch of the pedal! Hope plug will last like the older iriridiums I took out with 100,000 on them!
