Hello
I cleaned my intercooler about 2 months ago and checked the condition of hoses if there is any crack or delamination inside. I have found them in good condition. My D2 is a my2003 and I have red somewhere that LR already used better quality hoses from this model year.
Is it worth to change them to silicone ones anyway or if there is no any isseu with the exisiting ones it will not make any improvment?

If the current hoses are in good working order, why change them?

I noticed a slight improvement with silicon hoses. I only changed because 1 of the hoses developed a bubble. I’ve noticed no difference to fuel economy, and the power increase was only slight - maybe 5% at best going uphill. My biggest improvement before my remap was putting in a D2a intercooler in my D2 TD5

I have read several times that silicone hoses are better and lot of owners have put them on his car as improvment. I also have some doubts if these are really making improvment so this is why I have asked opinions.

The standard hoses do fail, the inside delaminates. The silicon hoses do not. I cannot see that there would be any performance differences between the standard hose and the silicon hose. If and when your hoses fail then you can decide between silicon hose or standard hose. Myself, I would leave the standard hose on until it failed, and then see what the prices are.

The difference in performance notices is probably when they are comparing the original DELANMINATED hose performance to fitting a new silicon hose. Has anyone really done a real test of a comparision of a NEW Genuine hose to a New Silicon hose?

I replaced my original hose because I could feel them swell very slightly when the engine was revved. They were actually in good shape with no splits or delamination.

My test was not done on a dyno, but was just an observation of my speed up a long, local hill dozens of time before and after the change.

I am confident that there was no change at all in performance, economy, turbo lag or anything else.

However that may be because I fitted black silicone hoses. I have been told the red ones are faster. :) :) :)

So I am convinced that if your hoses are good, silicone hoses won't make any difference.

And green ones give you lower blow by and therefore emissions! [tonguewink]

There won't be any power difference, there can't be, boost levels aren't changed, silicone is just a bit more reliable. (And looks pretty, if you are into colours!)

Yep people like colours.

You would have thought Black Silicon would be the most popular as it looks O.E when looking in the engine bay but no, Blue is the most popular . I suppose it's the bling factor, if your going to do a mod you want the world to see it easily.
Green not so popular, but Orange , if you stock those you'll sit on them for many years waiting for a colour blind customer to purchase them.

LOL!
It's weird.

My D1 came with blue silicon hoses, I've seen a few similar.

I got a set of silicon coolant hoses(yet to fit) and only chose white for them to make it easier to spot any leaks .. otherwise would have chosen black, but they were out of stock and only had the gaudy other colours.
