intake - cold air feed questions

so for a cold air feed for my intake....

just wondering:


-What kind of piping should i use? Hard plastic or bendable/jointed/flexible piping?*
-Should i run the cold air feed up to the current intake or cut a hole in the airbox and feed it into there?
-where's the best place to locate the "cold air"/intake end of the feeder pipe?
-Any other advice ya wanna give me?

thanks in advance,

bump.... anyone?

First I have question for you: will you apply some closed air induction system like BMC-CDA or K&N Apollo (better for performance) or you wish to use original air box (cheaper solution). In both cases better way required flexible pipe (because of simple bending and placement). This flexible pipe should be connect the input of the induction system (old or new) and place with cold air feed source. The best cold air source place is behind the front grill (just under the number plate). I have 147JTD (same or similar grill as your 147 1.6 t.spark) and I will to apply BMC-CDA model 85-150.
Good luck in your efforts. Dusan

as dusan correctly states, the best solution is to fit a kit such as the BMC CDA (any enclosed kit will work just as well) in place of the standard airbox and take a cold air feed from the front bumper. you will be best off removing the battery, battery tray and fuse box to gain access. you can run the cold air feed to behind the black plastic in the front grill but it will come out where the plastic has no holes (right on the edge) so the best solution is to drill some holes in this so it matches how the middle section is.

this is tried and tested and gives great results

I totally agree with Marko (probably because I am former owner of one Rover25, ha ha)...
Cheers Marko and best regards. Dusan

no problem. im a former owner of a 147

i think i have some pictures of my BMC installation on my 147 at home but for some reason cant access them at the moment. ill have a look later to see what i have.

That will be nice. Are these pictures for JTD or petrol 147?
Thanks in advance, Marko and best wishes from Dusan.

P.S. In case of mistake - I am very satisfied former owner of the Rover25 (1400ccm, 103BHP, K&N Apollo air induction system, 4-2-1 exhaust and free-flow backbox) and I am very happy to read your post about performance benefit after apply of BMC-CDA on your MGTF 160... I hope that Rover (MG) will take outstanding place in future.

thanks alot guys, that's a great help!

if you manage to get hold of them and wouldn't mind putting up? It'd be nice to see it!

thanks,
Phil

The material doesnt really matter to be honest, you can buy tubing with attractive funnels at both ends from places like halfords or ESP Design - Car Air Filters, Brakes, Suspension & Top Quality Exhausts - ESP Design Ltd

I woldn't bother cutting the plastic if your just using the OE factory airbox

As for location Id say as close to the front of the car as possibe maybe behind a grill or somewhere like that.

Here you go Cold Air Feed with funnel.

Universal Cold Air Feed Kit - Buy now - Fast UK Delivery - ESP Design ESP Design Ltd

You could mount it so the funnel was on the outside of a lower grill and either colour code it to the bodywork colour or go black so it blended in with the grill

here you go mate, no picture showing the filter itself but im sure you get the idea

All is clear and thanks for the information Marko... The cold air feed pipe runs from the front grill holes near to the left indicator and goes to BMC-CDA and from there runs directly to the engine throttle... I suppose that BMC-CDA was somewhere in the place of the old air filter box (or behind the radiator). Which type was using: 70-130 or 85-150 (if you remember)?
Best regards from Dusan.

that is correct. it was the 70-130. the 85 is only needed on the V6 models. as far as im aware the JTD uses the same intake as the twinsparks

@marko: thanks a million lad you're a legend! Deffo helps me get my head around it a bit easier with the pictures

Have you noticed a change in performance?

i found that with the BMC kit on rather than the stock intake the car was a lot more responsive.

i have just removed the BMC from my MG in favor of a reworked stock airbox (larger filter area) and have found exactly the same, the bmc give the car a bit more response however the MG seems smoother and sounds a little nicer on the STOCK system! weird.

for the alfa tho an enclosed kit with cold intake is the ONLY way to go!

Well I'm currently weighting up either a complete new unit ie BMC or using a GTA pipe and unresonatored standard airbox with a aftermarket panel filter in it.

Not sure which to go for. Both will mean removing items from the stock induction system, I just not sure which to go for

The cars a 1.8 Twinspark

If i can do it on my 147, i will be going down the GTA pipe/aftermarket panel filter route.

@marko: quick question dude - how did you attach the cold air intake to the front grill after you drilled the holes?

thanks,
Phil

with a tiny little cable tie, punch a tiny hole in the edge of the intake pipe and use a 2mm wide black cable tie to keep it held to the grille. to be honest it wouldnt move much anyway but this just ensures it behaves. being so small and black its unnoticable unless your really trying hard to find it

thanks again!
