For stock applications though, the standard Rotofab comes with both filter options since both flow more than enough air for a stock engine.

Speaking of more airflow, I was watching a YouTube video of the JLT Intake install on a Cadillac CT5-V Blackwing. I was surprised to see that the BW stock air box has a second opening in addition to the usual snorkel opening.
Might explain where the extra 18 HP comes from in the Blackwing LT4.
