I'd only ever use single point in my 1800ES, and when I tried multi-point plugs in my 97 V70 it developed a misfire quite quickly that was only cured by replacing the plugs with the standard ones.

Because your V70 is on LPG it would have had no chance of running on multi prong plugs. LPG is such a dry fuel they will never work.

Never had a problem ever with an NGK, and usually they're cheaper too.

I've had some odd faulty bosch plugs out the box. Other than that they have always been fine for me. With the B20/B30 engines I've always used bosch as they are slughtly higher heat range than NGK.
When running unleaded or even LPG you do need the higher range plug to disapate the heat.
