Hmmmm, I'll have to sleep on this I think

Maybe should put some thought into trying to utilize the knock sensor mounting hole, but I don't really want to effect the function of the knock sensor (which would have to be repositioned) but it would get rid of all of the problems with different series of engines and center plates........
Dunno, I have the #1 design locked away (V2 OEM fitment).
This vertical iteration I don't like the long spacing of the coil, lower rail could be issue, I know on my last COP set up shit was very tight down there getting it on and off with the horizontal set up. The center mount would need to be much larger and I'd have to go with a 4 coil mounting fixing method to get over the length of a one piece mount with the coils mounted vertically.
