Why hasn't someone made the same CAI as Spoon or Mingsters in molded plastic? Is it too cost restrictive? I know it would be a welcome additional option to CF. Probally less expensive also. So how come? The CAI is a functional item more than an astetic one. Sure would like to see it done.

My guess is that compared to plastic, CF does a better job insulating, thus keeping the air cooler.

Probably because the mold tooling costs would be $20,000-$40,000. Carbon fiber CAI's are made by wrapping cloth around a form.

Jay, this type of CAI would be ahead of any heat source. So don't you think this wouldn't factor? Incomming air would keep it cool and you could insulate the bottom over the radiator. I know the molding process is a more expensive but wouldn't the lower cost be more entising to most people and certainly wouldn't this lead to higher sales?

i've asked before whether 300 people would wanna pay 100 dollars for one. nobody did.

a small injection mold costs something like $10K to start with, and that's McDonald's toy sizes.

Wow! I didn't really think it was that expensive. Well, if it ever comes around again I would pay $100.00. Richard, don't you think dollar for dollar this would be a wise investment in the long run?

The quantities you could sell would never justify injection molding. This would likely be a pressure-formed or cast plastic application. Tooling for one of those would be in the $2-$5K range. What you give up is dirt-cheap part costs of IM and a bit of dimensional integrity. Could be done.
