iv just never understood the whole K series thing, for the ammount of money that needs to be spent making them go ok its not worth it IMO,
4age $500, headers+exhaust $600, air filter & inlet pipe $70, wiring mounts ect $500-1000. The look an the owner of the $10000 4k when you smoke him every single time, Priceless.
and if there is a K series that can smoke 4AGEs how long will it last? we all no a lightly modded 4age lasts forever same for a standard K series but a K series so highly strung so as to keep up with a 4AGE, i higily doubt it would last too long and then if it did the whole cost issue comes up again
STANDARD 4AGE FTW!
