wow, you got lucky, everyone i know hate nova plugs because they burn out extremely quick. i dont know why because they make some killer engines.

i run a P3 in my Alpha, they last about a gallon. in my Jammin JPX 21, i run the ofna turbo plug and im getting almost 3 gallons on a plug but they cost $13. and for standard plugs for the two nova BF limiteds i have (one modded one stock) i use the O'donnell 99 for the stock one and McCoy 8 in the modded one. McCoy might last longer but they are about the same. also i used to run nothing but P4s in my engines but the Alpha doesnt like the P4 and the JPX only runs perfect with the Ofna plug IMO.
