the cowl intake (for this car at least) is shorter, places the filter in a kind of "sealed" compartment from the rest of the engine and supposedly benefits from the high pressure at the cowl area as well
*not my car, but same design*
so you could say the cowl intake benefits more because the most part is away from any heat sources |
I am sorry, but I bet the stock intake does better in terms of less pressure drop and lower intake air temperature. Both are easily able to measured - no guesswork necessary!
The standard intake (that looks to pick up air from in front of the radiator) is exactly what you want.
To expand, the aerodynamic pressure in the stagnation zone (ie where air meeting the front of the car is brought to a halt - or near halt) is the highest of anywhere on the car. Typically, directly in front of the radiator is near stagnation pressure. We're not talking huge pressures (ie not like turbocharging!) but we are talking enough to - typically - make up for the pressure drop through the filter.
Also, by far the best at filtering - and still very good at low restriction - are standard paper filters. So I'd never use an aftermarket cone filter unless I didn't care about the health of my engine.
In most cars, optimising the airbox can be done cheaply and fairly painlessly. Seriously, I'd sell the aftermarket intake and filter and optimise the standard intake and box.
