I have both in my parts box.
Have been thinking on putting the 1.6l carby hat on my soon to be rebuilt Lwb Suzuki sierra 85ci small-block (<=

)
Mainly cause it will create enough space for a 2nd 50cal ammo can or storage tray (or even a future 2nd small battery?).
cabin storage space isn't exactly a problem in LWB I do like to carry spare belts, bulb, hoses, fluids etc under the bonnet & out of the way.
I believe the sierra air filter wins out in total filtration surface area over the vitara.
Will the difference be enough that at 4500rpm the vitara will actually be suffocating airflow over the sierra one or its just the sierra will take much longer to clog up so less frequent service periods for same performance
