Ive looked into the MPI intake...and found very little info on it, other than from your previous posts. When i priced the system it was outrageous like $3k+, compared to $1400 for the Ramjet. Id much rather the marine intake, looks like it would be alot easier to install. You know of any place to get a used system?
Heres another nice upgradefor the vortec intake : )
