First off these look awesome under your hood. The filters point right at where the air ducts filter air into the engine bay. My mechanic had the old stuff out in 10 minutes and the new in about 20 minutes. He had ZERO issues with fit. One small hose included with it did need a small trim but that's ok would rather it be to long then to short.
How does it sound. When you go to the doctor one of the things they have you do is breath while they listen. Inhale ..... Exhale and again.
This is what your engine is doing. I literally have been driving around now with the radio off so I can hear the awesomeness it adds to an already awesome car. It really wakes the car up and man does it sound great!
So on to performance, the ECU will take some adjusting to get use to how well your engine can breath so you might noticed anything at first but let me tell you it's like you woke up a sleeping beast. From a rolling start I wouldn't say you feel much but you definitely hear the turbos sucking in as much air as they can. From a dead stop or almost a dead stop hold on tight boys and girls your about to have a little butt pucker happen, you definitely feel it from 0 to 60.
I even went by my dealership and gave my sales guy a test ride so he could see, he has a Stinger as well. The grin and excitement on his face was priceless I see his car getting this upgrade in the near future.
