Denso's patented U-Groove technology gives the flame a groove to grow in inside the electrode where as a standard flat electrode crushes and prevents the flame from growing. This allows for more complete combustion even in the event of a lean air/fuel mixture.
Iridium alloy is combined with Rhodium to make for much better oxidation wear characteristics. The Iridium allows for a much higher melting point than a Platinum plug and has much higher strength and hardness than other Platinum plugs.
A laser welding process is used to join the iridium alloy to the nickel base. This is the only way enough heat can be developed to correctly mate the two materials together. Extremely reliable seal allowing for amazing wear characteristics of the plug
World's smallest center electrode of 0.4mm

Simple
Fast shipping! They came pretty much pre gapped only off by a tiny bit which was great. Just a little pressure on the gap tool and they were golden. Fit perfect car started right up first time and instant pep! A+++++

These plugs are Fantastic!!
The Denso 1-step colder plugs are a must have for any application over stock! Theses plugs pack a big punch for the DISI engine that really let you unlock it’s true potential. Every MazdaSpeed owner needs these! I also recommend changing the ITV22’s out every 7-10k miles to keep your Mazda running at peak performance.

Sweet Plugs!
Swapped out stock plugs for these. Gotta say there great plugs, highly recomended for stock or stage 1. Mine came pre gapped but i checked for accuracy, they were on point. Stage 2+ get two step colder.

Cheap Insurance
I have been using these plugs ever since I upgraded my car to Stage 2 and they have worked great. Just like the other review says, make sure you gap them to spec/preference, they do not come pre-gapped. Quality product.
