Since you've asked this question a few times in this thread and haven't really gotten an answer I'll try to point you in the right direction.
Depending on the application (NA or FI) there are different benefits to CAI and SRI. On an NA car you will see much higher peak gains from a CAI. Mid-range gains will be pretty close to the same though (again, application dependent). The downside to CAI is the possibility of hydrolock. This is when the intake is splashed with water (since it is down by the wheel well) while you are driving. The engine will stall out and sometimes may be damaged from hydrolock.
On a forced induction application with an intercooler, you will see similar performance values from a CAI and SRI on both mid-range and peak gains. This is because the factor affecting intake air temperature (IAT) is overwhelmingly influenced by the efficiency of the intercooler, not by the atmosphere the engine is breathing from. The complaint with SRI is that you're breathing hot engine bay air. Corksport has helped to limit this short-coming with the use of their intake boxes. The intake box helps to isolate the air the SRI is going to be breathing. Hopefully this answers your question.
thanks for giving the brief overview...appreciated. i had a CAI in my '06 and liked it quite a bit. the sound was incredible. i was only slightly concerned about hydrolock, but not much due to the fact that the filter curved upward at the end of the intake. that didn't make it impossible, but it helped. i never had an issue.
the thing that i like about the SRI is that i've read that they are better at improving throttle response than CAIs do. they are alos easier to install and maintain. however, that heatsoaking is making me hesitant. i'm not sure how often that will happen as i'm usually not in really heavy traffic, so it's just a slight con. i'm not sure how much those boxes are, but i did read on CS's site that they could help mitigate a bit of the heat issue. that is why i was curious as to whether or not they'd be making one.
i don't have a racing car nor will i use it for racing. but if i'm going to spend ~$200+ i'd like to get the best bang for the buck. again, thanks for taking time to respond. i'm still very tempted!
