Volvo OEM spark plugs
 

Do they need to be gaped ? IF so Can I get the gap ? Time to change from BOSH.

Not sure what plugs you are talking about. The only ones that need to be gaped are the old school ones with the single arm. They should come pre-gapped. The other ones with 2 and 3 prongs do not need gapped.

If you didn't buy those plugs already, just save the money and go with NGK plugs. I use them in all of my cars and I believe they are the best. I used to use Bosch as well, but I was never too impressed with them. I guess they are focusing on making other things rather than spark plugs. All of the NGK's also come pre-gaped.

+1 for NGKs, they're often the correct gap.
It never hurts to check the gap before installation.
