If you're asking about a shop.
It depends on their hourly rate.
Shouldn't take them more than 45 mins - 1 hour for the CAI.
Not sure about the SRI, can't imagine it takes more than 45mins to install... unless you have a Fujita SRI, which will take a lifetime to get right. (sorry, couldn't resist)
If you are talking about DIY...
A Ratchet Set, and screwdrivers, (and some of those thing you use to pop clips out if you own a GTS and you are installing a CAI, as you will be taking off the bumper).
Just some quick links I have.... You'll probably have to call and speak the companies, as I do not know if their are compatibility issues w/ the '09s.
