I must say, those air filters definitely caught my eye. I feel like a monster motor like that could benefit from having a bit more filter element to breathe through. I'm guessing those are the easiest filters to fit under the hood though.
Funny, I thought the same thing. Those tiny air filters on that big motor. I didn't take a close look with the hood on but you're probably right, there's probably not much room width-wise for the air filters. I would think taller would work though with that super stock hood?
