This may seem like a silly question, but is the Crawford Premium Plenum more susceptible to rust than a powdercoated plenum?

I am not sure what metal it is made out of, but I would like to know the downsides before purchasing anything.

Also, what types of metals frequently used in aftermarket performance add-ons are susceptible to corrosion, and what are the available options to retard corrosion and maintain shine?

 

The crawford plenum is aluminum. It is in a very high-heat, dry area of the car... I doubt it will ever rust.

 

i dont think aluminum rusts

 

I doesn't.

 

It wont rust. However, for $20 bucks, they'll powdercoat it for you in the color of your choice. Mine's powdercoated in the standard silver. BTW, you have made a great choice.
