Difference between P75 HF-2 manifold and P75 HF-3 manifold.
I am about to purchase a B18B P75 intake manifold on eBay. There are 2 available, one is an HF-2 and the other is an HF-3.
What's the difference?
EDIT: Just checked my current B18A intake manifold, it's an HF-3, so should I assume I need to get the HF-3?

there's 2 different p75 manifolds. obd1 and obd2. obd2 has a hole on the top for the evap purge solenoid. you'll want obd1 if you have a b18a.
