Offset bowl pistons.

Post by 36inter »

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

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.
