Default Why do people/ companies make steel/ stainless steel intakes?

I have seen today yet another steel intake, this one for an NA Corvette. All I can think of is laziness/ cost/ disregard for weight. Seems ridiculous for a "performance" car parts company.

Because someone will buy it, and they will profit.

It's hard to say exactly. It could be beneficial in certain instances because of the lower thermal conductivity, but what takes longer to heat up also takes longer to cool down...Maybe if you're going to the drag strip and icing it down between runs.

You can bend/fold SS sheet a lot sharper than AL without it cracking.

It looks nice, usually

Other than that

The early APS FMIC pipes were stainless steel. I know some people prefer it for issues with rubbing pipes and how easily aluminum can make a hole. Of course that's a fitment issue with a heavy bandaid.

My other thought is thermal expansion for a MAF tube diameter, maybe?

Super high boost applications?

Also aluminum does not do vibration well, and will eventually crack
