LOL!...hey, that's actually some creative thought process there. I don't know...maybe a little more complicated that I want to go and probably overthinking on my part as to the downside of the 2 different openings. The reality for the operation of my pickup probably doesn't get a big boost from a ram air intake. I think I'll just stick with the additional air inlet to boost available volume. I put the K&N filter in last evening. I would like to consider a more efficient air tube to the throttle body perhaps later, but really, how restrictive is the stocker?
