What are the differences between a regular and a K47 airbox?

[jbsaxman]

I have not looked into it too much. i would like to keep it GM, and similar to stock (don't want to make it a big gooseneck puller, just decent size BP)

Is the a-team the single, Mitsubitsi non-wastegated turbo, or is it something else?

Here is the thread on it. IMO it is worth the money. It's more efficient than the GM series turbo, plus it's non-wastegated so there's really no chance of over boost.

Here's the filter you speak of.

relatively common, most Vin F's from 97 Up came with it... I know that my 98 vin S k1500 does NOT have the k47

Odd both my 98 K1500 (S) truck, and 98 C1500 (F) burb came with the round filter

Turbine doc, wasn't it all rounds, just a bigger housing on the k47? I personally like the round filters the best.
Flat was thankfully gone by mid 96.

flat panel airbox: what a PITA, IMHO.
