Each one is numbered, install was a breeze they slide on plugs with ease. All the lengths same as factory. Installed with new plugs and coil. I idle lower, I rpm lower at high speed. I have better accelerations, with lower rpm. 80mph I am about 2800rpm. The plugs looked bad, so the new ones may be the biggest difference maker. But I would buy again and recommend.
