I've see a lot of chavs mainly that have a cold air induction pipe sticking out there front bumpers in different places and wondered if this actually makes any difference in performance at all? Especially seeing as most of them are using standard air boxes.
If they are actually worth it I'll pick up a black one or something (less visible/chavvy) and have it direct some cold air into my standard 1400 air pipe. :drool:
Are they worth it?

Cold air will always be a benefit for petrol cars. I run my cold air feed from my fog light straight into the airbox. Then again it's not a standard airbox.

If you see on the top right corner of the airbox, above the ram intake, you can see a hole where the cold air feed goes into.
Certainly didn't hinder performance on the rolling road and was up 5hp from standard (among some other stuff).

as the airbox feeds from the o/s/f wing (on my 8v anyway) isn't that the same thing more or less?

Well I had nothing to do this afternoon so I got some pipe and put one on my mk3 :p I'll let you know if I notice a difference :)

From the front air is forced into the pipe and into the airbox. From the wing there's no direct air so the airbox sucks in air from there. It's better to get rid of that and put a cold air intake from the front.

If you do it's placebo. You won't notice a difference (it's literally one or two horsepower) but the dyno will.

My homemade induction feed made nice gains on the rollers.
All I did was remove the front fog and put a bit of tubing in there that led to the intake of the airbox. Then I put a bit of mesh across the tubing as it was not the prettiest of sights.
This is how it looks......

Could fail an MOT if you only have one working fog light on the front :wink:

Is that right? I wasn't sure about this as mine only has 1 fog working on the front but it passed ok. While researching I read it only needed the fog working on the back and the fog indicator in the cabin?
back on topic, I have my cold air feed cable tied to the passenger side bottom grill :P No idea if it makes a difference as I've never run the engine without it, but it roars like a beast :evil:

A cold air feed is good...cold air is always good.
But, Ram Air only works on a sealed induction system...so if you go to the trouble of finding the highest pressure area at the front and duct aid from there, you will only see the (small) gain at high speed with a sealed induction system...and holes in the airbox and you lose the pressure.
You can add as much cold air as you want...but any holes in the airbox wing side, bottom or otherwise and you WILL be sucking in warm air as the engine will suck from the point of least resistance.
So a totally sealed airbox is best - except if you hit lots of standing water you run the risk of hydrolocking the engine.
Just ask the owner of my first GTI who hade to replace the engine after a period of flooding!
It's all a balance :-)

my cold air feed pipe sits behind the bottom right vent on the back so you cant see it at all
the cold air feed pipe is normally silver inside ive just sprayed this black job done and not looking chav

All fitted front lights need to be in working order, swap other fog for reflector and remove/Hide loom if you get any grief from MOT, traffic cops could be a bit more difficult.
-
According to VOSA front fog lights do not need to be in working order for an MOT, the rear fog/fogs is a legal requirement. I only found this out on Friday due to me taking my VR6 for her MOT.

On my old 16v I had hella twins, I took out the center lamp and replaced it with a big trumpet (got it from a data cable box from site) I then got the 8v trumpet from inside the 8v airbox. I got a hole saw same size as that, and then made the original hole on the airbox bigger. I sealed the 8v trumpet to the air box then got a hose to connect the two.
The result was 10mph down a 1.1 mile straight :wink:
Also had to cut the hella's to make it fit. I didn't mind as mine where cracked and in bad shape.
I recommend this to anyone.
