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

They are the same tbh, just rebranded!

The car already has some stuff.

Piper cams stage 2, remap, KN, if I fit a ktecmanifold what should be the diameter of the rest of the line?

60mm?
