Which one? I'm thinking of the second or third link as has smoother internals?

 

[Allen_]

They'll all do the same thing.

Silicone will help with heat.

 

[celica]

Thanks

does it matter if its ribbed inside or smooth?

 

[Allen_]

Hmm. It's only a feed so probably not.

Be different if it was an actual intake.

 

[celica]

Should have said it is part of the intake

itg maxogen

so it's the feed which is sucking in the cold air into the carbon air box

 

[Allen_]

Sorry wasn't clear.

I meant it's not the induction hose (from box to throttle body) so the small amount of airflow disruption shouldn't effect performance.

Never seen a Maxogen in real but from pictures it looks the supplied cold air feed is ribbed anyway.

Thanks

yes the supplied item is ribbed
but the one I've picked up is perished and out of shape
