I have the feeling 2005, 2006, 2007 production of novarossi glowplugs were not long lasting as they were in 2003. The glow plugs have short life span, sometimes last only 20 - 30 minutes. It seems the glow plugs cannot stand long period of high operating temperatures ( I live in tropical country ). Lately I have to prepare 3 - 4 glow plugs for 1 day racing ( 1/10 engine ), and 4-5 glow plugs for 1/8 . Currently my glow plugs are easy to die resulted from high operating temperature ( 110 C )

Anyone have the same feeling ?
I am 100% believe that your .21 come with 0.7mm head shim from factory (if it is 35Plus 21 or 359) then you need to increase to 0.9mm. In Europe they are using 0.7mm but in Asia and down here we need extra 0.2mm due to ambient temperature is higher than Europe. Also use C8 plug
For .12 is should come with 0.3mm then add other 0.2mm
