Ordered these for my 2011 Honda Civic Si and they came gapped perfectly (though I did check them still with my gauges). I ordered 4, but only three arrived, so one was lost and I had to wait for them to send out another one, which they did. All in all, these were perfect and easy to install. No problems after 6000 miles on them.

I saved lots of money by purchasing these plugs here on amazon versus at dealership. Also by installing them myself. Just make sure you have all the tools needed before you begin taking stuff apart. There's many DIY posts out there that will help you.

Fit perfect on my 2011 civic si. Car seems to run smoother. Fuel consumption appears to be the same. Did not really gain any mpgs.
