Safety of aluminized steel piping for intake

Hello all-


I'm debating using some 2.5" mandrel bent aluminzed piping for a smoother intake to my turbo, as well as for intercooler piping. My question is whether or not the aluminized coating is safe enough to use on the intake side, or if I need to worry about corrosion of the steel leading to turbo or engine damage.

I know this has been discuessed a little in the past with regard to making bigger IC - TB pipes, but I don't recall any decisive answer.

I think you answered your own question....There's a reason why all intake components are either plastic, EPDM rubber or aluminum and why all exhaust side components are cast iron, aluminized steel or stainless steel.


When my car gets back from my indie, I'll take a picture of my IC setup...

ricot -

From my experience, you may not have much success with pressure bending stainless....It likes to crack if it's not mandrel bent.

Mike -

on the topic of plactic, I've thought about using pvc or something for intake/ic piping, but my concern (other than getting flamed for doing a hack job) is that it can't stand up to the heat.

I think you'd be OK using PVC on the intake but not from the airbox down to the turbo, or on the throttle body delivery tube.

I don't know the melting point, but I know that it throws off a chlorine gas when it burns....

I saw a guy on a honda forum who used PVC on the Turbo to Intercooler side and it melted in less than a week after his install and wound up causing him damage to the turbo and intercooler due to melted bits of plastic moving around in the system.
