2010 nissan versa 1.8L spark plug torque spec

bosch or NGK mag wires are best.
plugs any you want , if car short miles car, every year go cheap plugs , if hard to reach go best plugs.
I like NGK the best, but there are other good brands.

This requires a certain amount of mechanical skills and knowledge of how to use a torque wrench properly. To begin the process know that the spark plugs are recessed deep in the valve cover. Follow the high tension 8mm wires from their individual coil-paks directly to the respective plug and carefully remove. Now using a 5/ 8" deep well plug socket and an 8-10 extension carefully remove the plugs. Install new plugs (spec per mfg.) I like the iridium then platinum, but check to ensure gap is correct before installing the new plugs. Now take plug and insert into plug socket then carefully lower into recess until you contact threads lightly. Rotate plug clockwise with very little pressure keeping plug socket 90 degrees until you get proper thread engagement. Continue installation of each plug then torque to spec, and reinstall all wires.

remove cop (coil over plug)
blow the sand out of the spark well
unscrew spark plug, CCW, counter clockwise. RHT
gap new plug to under hood sticker spec.
put back, set torque to spec, 15- ft/lb most cars, look it up.

Do you have oil in the cylinder or around the spark plug?

You must remove intake manifold ( make sure you replace gaskets) remove coils and remove spark plugs denso iridium tipped plugs are the recommended plugs to go with
