Well Brad the CIS cars cars are very finikey. They were the first real forey into mechanical type fuel injection. There were no sensors to lean out fuel ( management ) . it depended largely on mechanical adjustments to fuel pressure etc. Given that, the AFR is critical , and even radical changes in teperature can ause backfires.
Blowing the air box is basically a backfire through the intake manifold.
The CIS cars use a plastic intake manifold ( the air box ) fastened to alluminum runners that atach to the heads.
I nm ycase I gave it special treatment , My service manual was misprinted and had me hook up the ignition wires wrong. So I was dumping in fuel into the intake without igniting it. Definitely a bad AFR .
then it eventually lit , and the rest (along with the airbox ) is history ..
oh well . life goes on .. check out my thread in the 911 forum for mre details, there is one about ' it's all over " and the other one about "flash bang .

Clive,
I still have that spare 5.0L 928 engine sitting in my garage.....Now is the time to see if we can try to shoehorn it into your 911!

Clive, this $ucks bud ! If it happened before Hershey you could have maybe pick one up while you were down there.
Why not make a Want to Buy (WB) post on the UCR web site to see some one has one for sale.... it could hurt.

I just read some of the post on the 911 forum... it appears Porsche made the air box to work like a "fuse" in the case of a major intake backfire the air box would pop instead of something else. Good luck bud... .
