Offset bowl pistons.

Morning all, I've never used these, does the bowl sit away from the plug or toward the plug. Thanks.

Towards the plug, the idea of the offset bowl is to concentrate the mixture around the plug. Supposedly giving a better burn.

I reckon you mean the likes of "MINI SPARES EVOLUTION LIGHTWEIGHT PISTON" with offset dish.

If I rememeber rightly the offset dish is supposed to show toawrds the front of the engine, i.e. where the main chamber in the head is positioned.
