| There is a correlation between air density/temperature, and timing for optimized performance.
Where IAT control becomes real important is in preserving this relationship. If you increase airbox temp, without retarding timing, you start losing optimal power/efficiency.
Later model vehicles provide a temp sensor post CAC just for this purpose. For the earlier models, IAT dampening and containment is more important.
As for the thread topic, it must be addressed individually. If you take a LB7, throw an ATS turbo on it and run it to 38 psi, and use an aftermarket purolator (crap) element, you have just created a problem, and a turbo hazard. The filter minder will alert to this, but unfortunately few people know how to read it, its not a good design for interpreting. But it is accurate. If your filterminder is in the green, then you are under 10 inches water column of pressure drop between the inlet and the minder. Having personally tested this, you can not improve the performance of the TD vehicle (20 psi boost) in a significant way, even if you remove all 10 iwc. While every inch is worth removing, for the improved compressor efficiency, the exotic cost for such small gains must be weighed in accordance with limits on sanity.
(my) Conclusion? aftermarket elments and intakes are arguably the single biggest waste of money in our trucks. | 
so insurance is getting me a new hood 
and i was thinking about a ram are hood. will they work functionally for any aftermarket cai?
