Leon Cupra SMIC arch vent (poor persons job!)

[CupraUK]

A cheap and cheerful way of venting your IC like an S3/TT (About £3)

You'll need:

Parts - B&Q 16 Louvre Aluminium Boiler Vent, Rivets, 4mm washers
Tools - Stanley knife, drill, pencil, rivet gun
Time - About 1 hour

1) Get yourself an large (they do a small and a large) 16 louvre aluminium boiler vent from B&Q, they are £3.08. The advantage over plastic is that you can bend them nicely into shape (keep bending it until it sits nicely in the curve of the arch)

2) It comes with only 4 holes which is not sufficient so drill two more at the top and bottom making 8

3) Jack your pride and joy up and put on axle stands or something that will keep you alive. Take the wheel off.

4) I did not remove the inner arch. Hold the vent up against the inner arch and bend into shape until it sits nicely all the way around.

5) Remove the wheel and mark up the wheel arch by drawing around the vent, mark where the louvres come to and then draw an inner rectangle when you take the vent off which is well inside the holes

5) Get a brand new stanley knife and cut out the inner rectangle. Be careful, you will need to put your hand behind to do this so don’t cut your fingers off.

6) Get some rivets and a river gun. Important: The plastic is quite soft so you MUST put 4mm washers on the back on the rivets to prevent them pulling through.

7) Rivet the vent on (Washers are on back of rivets on otherside)

9) Either leave as silver or paint black (I painted black)

looks good

No chance of water or dirt getting up there ?

 

[CupraUK]

Difficult to tell. I would say no more chance than the official Audi vent has.

Certainly when moving the wind from the wheel would be moving the air away, rather than torwards the openside of the vents.

I did this job 3 years ago this month and I've not had any problems.

 

[CupraUK]

Just thought too... I bet tons of water goes in the front anyway when its raining hard.

 

[Cupraloon]

Look good matey, i may well give this method a go seeing as it's only £3, and a bit of effort rather than £20 and a lot of effort...

 

[BCM]

Top Guide Mate!
Water would be good! Get the IC temps down!
I was lookin at water spray on both IC's on the R!
Will prob be doing this on both sides bit gonna go for TT ones as they are black and plastic!http://www.18turbo.com/ttvent.html

this seems a good idea how ever i still believe crap more than water getting up there could be a problem.
So my idea is that a bit of fly mesh which is often used with loures could be put behind there to cut down the wheels flicking stuff up in to there

Funny you should say this, cos i was thinking the same thing, and thought the smic could get hit by flying debris, so went to halfords and a got some of that thin mesh you can use to do body repairs for £1.49.

So when i do mine, i'll stick that over the inlet, once it's been opened up a bit..

 

[RikH]

ull just really want to keep mud/stones/gunk etc out that could damage the core of the I/C
louvres facing down its unlikely you'll get stones through the slats but there is a chance-bit of meshing should solve it

 

[Cupraloon]

sorry probably should have made myself clearer....

i meant i was going to put some mesh over the front inlet where sargey has cut his bit out (see pic below) to stop any depris hitting the I/C..

[RikH]

defo need something there!

 

[CupraUK]

There's nothing there normally, just because the hole's a bit bigger doesn't mean that it did not stand a chance before of getting a stone or something in there. I'm always clearing stones, leaves and other crap out of the entrance hole.

I've never heard of anyone having a problem.

Standard intercooler can be had for as little as a 10er anyway!

 

[Cupraloon]

Standard intercooler can be had for as little as a 10er anyway!

Quite possbily matey, doesn't mean i want to have to keep buying a replacemnt every few week/months tho....

That would be complete madness, when a simple piece of mesh over the hole will stop it....

Or even not opening it up so big, would probably solve it aswell Eh...

 

[BCM]

True, simple wee bit of black mesh!

 

[CupraUK]

Maybe put a bit of Cupra grill in there (you'd have to do the other side of course)

 

[tris]

So have you noticed anything with have the vent?

 

[Big_daddy]

Well ive removed the air vent from under the bumper to intercooler and it has made some improvement.
Quicker cooling and a lower temp compared to my previous log
