Application is for a basically stock b18c

These things should be pregapped but when I took mine out I just wanted to double check. Every single plug has a different gap. I know this is minor but I don't know the correct gap. Can you please help?

Question 2:
The guy at the autoparts store sold me Standard Spark plug wires. I know wires are all the same for the most part which is why I bought them. Just wanted some feedback if anyone has used this brand before.

 

My '95 GSR (B18C1) wanted the spark gap to be 1.3mm (0.051").
