CAI vs. SRI for 2009 Corolla S

Hey y’all,
I have a 2009 Corolla S with the 1.8-liter 2ZR-FE four-cylinder engine. Looking at air intakes for the first mod and I wanted to see if you all had suggestions. Im fully aware of the difference between the sri’s and the cai’s but I want to hear from you all. Will the cai require me to move things in the engine bay around, if so how long will that take? Mainly looking for a better sound, not too labor intensive, and mpg... I know that the hp gains are minimal. Would cai or sri be better? Thanks!!
use a cai, obviously the installation its more complicated because of how long it is and the amount of work space but cold air is better than hot, so a bit of work is worth it, also dont go crazy on big puddles
