bast LA 4speed intake?

I think that an intake should be tuned to the cam and use of the car. A 4 speed eliminates the need to match RPM power ranges of a stall speed to what the engine produces, but your camshaft and overall CFM is what will dictate what is best to use.

For a street car, I still like a dual plane with high vacuum signal, for more torque. For a high heat, high RPM car, an air gap could be useful to keep the air charge dense, but if you see cold driving conditions with your car or have hood clearance issues, it can be more of a problem than aid.
