So I'm going to ditch my MAF, and as such need a length of silicon hose to run from the OTRCAI to the throttle body.
Given it's a 90mm TB, I'm presumably going to end up with 4" hose (102mm).
Where's a decent place to get this from? As I don't particularly want to order 1m of it for £80 or so if I can avoid it...
I did manage to find a 'coupler' (which just seemed to mean 'short piece of hose') that was 150mm long, but I don't think that's going to be long enough, I need to measure to be sure.
Or will I be better off just getting a coupling piece the same diameter as the MAF to join together the 2 existing bits of hose...?
Gratuitous old picture to illustrate what I mean...

Funny I've just been speaking to a guy called Lee at SFS Hoses in Luton (01582 509250) and they will make up any hose you want. He does loads of racing team hoses etc. on Monday I am going to take the Ro down and get all the hoses measured up. He said if we can get 10 forum members to get a set of hoses then he can have all the tools made and discount will apply but nothing money wise has been mentioned. But if you pop down to him he will measure whatever you need there and then.

i was going to order all my stuff through them or Ash performanceI'd say ~£20-30. For reference, scroll right to the bottom to see what I paid for mine: http://www.xairwakeboarding.com/products/xair-perf...
I shall browse the bay, needs to be 180mm long, 4" diameter. How hard can it be?!
Forgive my remarkable ignorance, but there's presumably no drastic consequences to making a hole on it?
Let me elaborate, there's a hose from driver side rocker cover to intake, presumably some sort of PCV thing. Is this strictly necessary? If so, will need to make a hole in the silicon hose

thats for the air into the head, for the PCV.Forgive my remarkable ignorance, but there's presumably no drastic consequences to making a hole on it?

I suppose as its just air in you could leave maybe leave the port on the head open and have no hose attached

I've used these a few times
http://www.carbuildersolutions.com/uk/
Normally best to give them a call as their website doesn't cover everything they do

Could I not just get one of those little air filter oil cap things and put a cap over the valve? More shiny shiny you see I suppose as its just air in you could leave maybe leave the port on the head open and have no hose attached

So say something like this:

Tell me what length you need and I'll see if I have it. I have plenty of off cuts laying about
Ahhh crap, caved last night and bought a metre for £45.71 and it's been dispatched already!I too shall have some off cuts now!
Thanks though, much appreciated

What's the 'right' way to cut it?
Looks like put a jubilee clip around the area to cut, and use a sharp stanley knife following the edge of the clip?

One thing I thought about before but never bothered because the MAF was there, but could you not wrap the silicon hose in heat reflective tape?
http://www.ebay.co.uk/bhp/heat-reflective-tape
Would this (aside from being shiny, I know, I know
) give perhaps a slight benefit to preventing heat soak through the intake hose?
I don't seem to be the only person to have considered this (see google images link below), although I think the gold might be a bit much for me (I know somebody who might like it though?)

Gary has done this, i plan to do a few bits toohttp://www.ebay.co.uk/bhp/heat-reflective-tape
