January 2011 discussion thread !!!
md's 5/16 spacer is just the most popular. its the best compromise of torque and hp improvement. going larger like a 3/8 will give you more more up top but less tq if i remember correctly. then there's also angled spacers. basically as long as you give a little more room to the front 2 cylinders, you're fixing the problem of the oem plenum.
Motordyne is just stupid expensive for no reason.
There's not much difference between a 3/8 and 5/16 and I got a good deal on the 3/8.
I almost got an angled spacer a while back (Z1) but I found evidence (dyno) that it wasn't too great.
