This kit is designed for someone who already owns a Flat Filter injection system for stock throttle bodies and wants to upgrade to the EVO throttle bodies.
Includes Bottom Plate, left side EVO plate, 4 velocity stacks, 2 feet of o-ring cord stock, 8 titanium bolts to fasten to throttle bodies, and the top plate with no holes.
If you have an R6 flat filter, you may want to swap out the back plate as well. On the R6 that back plate has a cut out and housing for the adjustable velocity stack motor. That part number is 602-802-2 and costs $44.00
