Supersprint or K-Tec Manifold

[Cuprafenix]

I'm in a dilemma.

What should I choose for my williams?

Supersprint or K-Tec.

Supersprint is more expensive.

K-Tec has 2 options more cheaper, the ss steel and the mild steel.

Actually as I live in Portugal and it doesn't snow and doesn't rain alot I was thinking if I choose the K-tec to choose the mild steel one.

Any help would be apreciated

The k-tec 1 is just a copy of the supersprint

So if it's a copy and it's cheaper is good option correct?
