Want to install a cold air intake on my impala but running into some problems. The HUGE stock air intake system has the emission control module and the transmission control module at the bottom that is covered up by the intake case. But I have to remove the intake case to gain access for the intake. My question is what should/shouldn‘t I do and/or any advice. Really stuck on this one, everything is appreciated. Thanks!

Already has a factory cold air intake system, aftermarket will be no better and not as good
like the other guys says , GM spend millions designing and making an intake system with temperature control . MAF , MAP charge density etc etc so you are unlikely to improve it , trouble with so called cold air systems is they only work with carburetors in untuned 1975 and earlier cars , not only do they take air from under the hood where it is HOT but some even have oil based filters which prevent the MAF from working, the only tuning you can do on injection systems is re-mapping or supercharging without spending a fortune
GM mounted a TCM in the air filter housing? What kind of design is that? However, besides everyone else being correct that cold air intakes are a scam, since you already have one, if GM put it there, it is likely to protect it from water, or to keep it cooler. An odd idea, but they didn't put it there just becauseplenty of room to put it elsewhere if they wanted. So on that basis alone, I would not attempt to do better than GM. Edit: After looking at the picture, and the cooling fins on the TCM, it's pretty obvious GM mounted it there to gain advantage of airflow to help cool it. Just to make a point.GM went to this expense/hassle to integrate those into the design, and your aftermarket how-many-dollar CAI manufacturer couldn't? That should tell you volumes about how little they care about anything, except taking your money.
