does this has 0.004 size difference? is it issue ? oem is 0.004

If you are driving a Mazda Skyactive engine newer than 2012, you should be o.k.. In 2012, the stock Skyactive 2.0 uses the OEM spark plug with 0.032 gap, then the Mazda revised the spec to 0.040 gap for the vehicle after 2013. The newest spec is 0.044. The older 4711 spark plug has 0.032 then I just notice it is now 0.040. As long as your car is updated with the latest Mazda software, you should be o.k.. Personal note, this Denso 4711 burns better in my opnion and it is cheaper too.

work to nissan versa 2009? engine 1.8

According to their website, yes.http://densoautoparts.com/find-my-part/vehicle-selectionAssuming it's the s-1.8L engine.

Would it fit corolla 1.6l 2011?

There was no 1.6L engine offered for a 2011 Toyota Corolla so I assume you have a 1.8L engine which would take Denso IXEH20TT or Denso SC20HR11 (Iridium Long Life).
