I put a set of ModRods siden panel vents on my M8 (cant beat the unless you make your own) and a MadFab Designs gage cage on ... Guy on here makes the "madfab" one, can't remember his name though, but I liked it better than the AMP one because it has a screen on it.
IMO, people go overboard with venting. The cage vent and some side panel vents are all you need.
I would recommend the gage cage though, youd be surprised how much heat that vent alone lets off.

The MadFab one is mine. Not only does it come with the mesh/screen installed, it has an adjustable angle and it's a smokin' deal for a useful product.
PM me for details. I make them for 05's to 11's, all models.
