MKVIII fan all the way!!!!!!!! Do it once and never look back. They are MONSTERS!!!!!!!!1
mk8 fan 97 pulls 4100 cfm.......... The only other fan that pulls more air is the 2001 dodge viper fan, pulling 4300 cfm.
If you drill the rivets out of the Mk8 fan motor and use bolts and nuts to mount the new motor, You can always keep a spare motor in the trunck, In case-the orginal spazs out (which is a rarity) but for cheap insurance, You'll never get caught short. The motor band new is $100.
