    More power at lower rpm with out lugging
  

*by M***1 on Reviewed in the United States 🇺🇸 on 17 January 2018*

These plugs are great! They're pre-gapped... just screw them in and forget about them for 100,000 miles.Put these in my 2015 Tacoma 4.0L V6. Subtle but definite improvement from the stock plugs with 30K miles on them. I have the 6sp manual and its easier to start out in 2nd gear with no engine bucking/lugging and the acceleration from stop lights feels a little peppier.As a side note... I also put NGK Laser Iridium plugs in my 4cyl 1250 Bandit motorcycle with the same results. The bike is already a torque monster, but just putting in these plugs the bike can cruise 300-400 rpm lower before the hint of lugging shows up. Acceleration from stop is smoother and more powerfulYouTube has videos from Cycle Solutions where they dyno test Harleys comparing new factory plugs with new laser iridium plugs and hp and torque go up.How? Compressed air is actually and insulator. As the pressure in the combustion chamber increases, the electrical resistance between the spark plug gap increases. The spark will form and punch through that insulation faster from a fine-wire type spark plug  - which is the laser iridium design (fine wire type also used on aviation plugs). The spark forms faster because of the fine-wire design and using iridium makes it last a long time. On a dyno chart, this results in your torque curve starting about 300-400 sooner and hanging on just a little bit longer at the high end. Depending on the tuning of your engine it may indicate a few more horsepower. But where you feel it is accelerating from stop where the engine can get into its torque curve sooner.
