It's still debatable if an intake system even offers any real gain. I'm not fully convinced a drop in helps either. But I personally have the drop in filter only cause it's cheap. But I wouldn't drop $300 on an intake unless you really want the noise.
Until someone PROVES to me, with cold, hard evidence, that an aftermarket intake either gives documented power ABOVE AND BEYOND any dyno variances, or margins of error, OR a substantially lower charge temp, I am sticking with the factory intake, probably even including the hoses/piping.
It is also less hassle/problems just in case I am forced to go back to my shitty dealership for any reason whatsoever (these aftermarket intakes are much more noticeable as NOT being factory parts, even including the Mountune using the stock cover/top, than even a well done cyborg/hybrid turbo setup, by the average Ford tech, who does not deal with these cars very often).
I am still debating whether or not to even do a drop-in filter, since for every other platform I've ever dealt with, they have been proven to not do a thing for power, and can even contaminate (with oil AND dirt) the MAF sensors of those platforms/engines which DO use the MAF sensor for actually DIRECTLY controlling the engine functions, unlike ours which ONLY use it as a monitoring device.
IF aFe, AEM, or airaid bring a dry flow type panel filter to market for our cars, I will get it, or I might just try the ITG oiled foam panel filter, since the foam oil is so viscous that it cannot be blown back into anything downstream, even if soaked in said oil, unlike the thin oil viscosity cotton gauze type oiled filters so popular on here and elsewhere.
