ticking noise is normal... if you worried get a long flat blade screw driver or something metal wit plastic end and put the metal end on each cylinder and you ear on the plastic end.
Listen for any cylinder that sounds different to the rest, if all the same then ticking is normal. Unless ur lifters are acting up, if so get some cleaner and run it though but honestly the best thing for it is to every now and again redline 2-4 gears few times once car is warm and you are driving.. if you drive like a grandpa, its actually worse for the engine believe it or not...
as for my font colour its just standard?
Edit: Oh the name of the part is a upper Plenum, and the part of the plenum your pointing to is the throttle body... FYI
