Very specific size and shape, and is smaller at the one end than the other.

If replacing, you either need a genuine one (pricey) or a Forge replacement (also pricey).

So pricey either way sadly for a small bit of hose. However, it does have to be heat resistant....

As Welly says you cant put any old silicone pipe on there, it is very special formulation, for the immense heat generated there, and always feels greasy to me..hence the cost :faint:

Forge ones are made from flourosilicone which is oil resistant and heat resistant... normal silicone can be used in some circumstances though, I use a 60mm to 51mm reducer on my GT30 but I still have the K04 heat jacket wrapped around it... on top mount big turbo conversions its a non issue as the silicon is much further away from the manifold heat source...

If you need a replacement hose then the Forge one is the best option... better and cheaper than the OEM one... its designed to fit properly as its a different angle/shape to the normal 90 deg elbows...

Forge is the best place mate to be fair.

Yep, it only comes in 'ocre' I believe they call it. It's a gash colour yes, but that's the way it is....

OEM ones are similar money for a lesser item.
