what is the gap preset on these spark plugs in inches?

Most Bosch Spark Plugs are factory pre-gapped for popular vehicle applications. The gap measurements are indicated either on the box, or by the part number located on the spark plug shell. X suffix = .044" Y suffix = .060" Z suffix = .080". However, it must be noted that wire-tip or needle-tip plugs can afford to have larger gaps as the spark occurs at a lower voltage if one end is pointed, leading to a wider spark and better combustion of the fuel-air mixture. Gaps should never be adjusted on the OE-Fine Wire-tipped plugs - should never be gapped by the installer. Attempts to do so might damage the plug/the delicate tip. What is more important is all the plugs should have equal gaps, or there might be engine knocking and vibrations.

Will this work for Lawnmower ?

Only if your lawn mower has a 2.2L 4 cylinder engine.

14mm socket is standard - 10mm and 12mm are less common, found in only some motorcycles. What is more important is the thread reach - too little or too much are both bad. Amazon has a nice system of selecting the vehicle and showing which plugs fit that vehicle. Bosch has a similar system at BoschAutoParts.com. Remember to NEVER gap-adjust iridium plugs.

Will this work for honda crv 2016?

Bosch 9603 does not fit the 2016 Honda CR-V. The correct Bosch spark plug for this application is 96310. Thank you for your question.
