I blew my last glow plug which was an os 8,i have a couple os a3's would it be a good idea to use a 3 temporarely untill i can get to the hobby shop?
 
A3 I believe is the old number for the OS 6, which is a hot plug. That's what I run, you may have to adjust your tune a bit.
 
The A3 is a hot plug as alien stated but it won't hurt your mill to use it. As stated you might have to re-tune but hot plugs generally provide better idle and acceleration than cold plugs. Cold plugs will produce more power but may idle more roughly and be harder to tune.
