What would an air ram type air filter really add to my 2.4L 98 Frontier?
I feel the engine could use more air intake as when a wing nut on the air filter cover was missing I could hear a whistling sound on wide open throttle.
Does that mean that my engine is pulling more air than the stock intake can provide?
What happens with the air flow sensor input with an air ram filter, what effects on the system without this working?
Any good, bad, indifferent results - experiences?
TIA
