i generally use shell - mainly because it's my closest to home. i've never had that kind of power problem with it. and i love the fact that if you do engine work, valves and pistons are very clean. some cars run on cheap crap are crudded up badly, and just like the advertisements show, intake valves are caked in crud. that may also be true with other brands, but this is my experience.
translation: "we spray a $3 can of cleaner into the throttle body. maybe."

Oh, come on. This sounds like your typical dealer profit-building bumpf.
The "plenum and air intake" NEVER need attention. NEVER NEVER NEVER!.
The intake valves and ports, plus any combustion chamber deposits, will get cleaned when the injectors are cleaned. From that description, they're probably doing a Motorvac. Motorvac isn't bad, just not often necessary.
If the air/fuel balance was off by enough to matter, your Check Engine light would be on by now. Or your fuel-trim numbers would be way off normal.
Now, the throttle-body clean IS actually a pretty good idea, but that takes about 15 minutes once the car is in the bay. See what they'd charge for that alone. If it's more than $50, skip it for now.

ok, when responding to a post, don't write below someone's sig. for both email and usenet, a reader app looks for a line with two hyphens, two spaces and a carriage return in a row. when it sees them, it ignores anything below and won't quote on any response. to get your response quoted above, i had to copy and paste or i'd simply have tegger's response and writing to you would make no sense.
the best way to read usenet is to use a specific usenet application, and point it at a proper usenet server. there are a multitude of apps for all o/s platforms, and there are free servers if your isp does not already provide. others will recommend i'm sure.
re your car, to "inspect" prior to determining whether this operation is actually appropriate or not, they would need to borescope [if they wanted to be less invasive] or they'd need to remove the intake manifold. since you already know they're not doing either, that tells you all you need to know about their sales ethic here.
The term's been in use for years; Induction and exhaust, the two manifolds. You never heard the term 'induction noise' for an engine that's run without an air filter?
Perhaps it's a regional thing?
