"smooth bottom" cowl induction air cleaner???

[camarojoe]

I tend to agree with my brother, that "flat bottom" one is actually not a cowl induction air cleaner. Its a closed element pre-69 air cleaner with the cowl induction style lid. I got stung with one of these myself once, not realizing what it was until after I bought it. All CI air cleaners have the snorkel pointing towards the passenger side fenderwell when installed... what you have is an earlier non-CI, closed element air cleaner with the original lid swapped.
