I needed replacement intake air ducts, because I had one good intake duct and one off of something else.  As I’m sure the rest of you 750 people know, the ducts are very hard to come by.  Frankly, I wasn’t all that pleased with the design anyway, so I stopped hunting for one and came up with my own.

Here’s what I used:  Rack and pinion bellows for a Prizm.  You can buy them right online from O’Reilly….

Item No: K9321

$26.99 per Box (at this writing)

Bought two new ones and cut them to fit.  Works great.  Has some give, so it will handle the vibration.  Much easier to connect to the carbs, and seals better than the originals I think, too.  I haven’t put the carb clamps on yet because I don’t have any.  I’m working on that next but it’s such a nice snug fit I almost don’t think it’s necessary.  It’s automotive grade rubber so it should be okay with the heat.

Did all the work on it while the air box was still in the frame too which was no small feat I might add.  Still retained all the original components (except the ducts).

Here’s a shot of the business end.

Here’s a shot showing the bellows are actually sandwiched in between the clamps.  The seal is impervious to water.  All the air must pass through the air box opening and the filter.

I did this on my 1982 CSR and it worked great.  It is available at automotive part stores.
