You must have aluminum baffles to make the front, back and sides to which the SJ plenum forms the top and attaches with nutplates and screws.lostpilot28 said:Hey guys, I'm going to buy the Sam James Cowl and was thinking of going with the Plenum. I thought the Plenum didn't need baffeling to work. Am I correct in reading your posts that baffeling is required? Is it used only to attach the plenum to the engine?...

Alternately, what if you don't go with the plenum? Is the Van's baffeling sufficient for cooling? What is the benefit to the SJ Plenum? Thanks.
