First of all, I do not know anything about intakes (I'm a n00b). 
I have a few questions regarding any intake... (BTW I'm leaning toward the TPR intake)
1. What is CEL and bogging?
2. What kind of sound does any cold air intake make? Does it make a loud roar sound? In high RPM's or low? (I want an intake for performance and also for the sound; I love the roar sound in high RPM's)
3. Will I notice any gains?
4. How easy is it to install myself?
I think that is it, thanks!
