Im after an induction kit for my 2.5V6 estate, but looking at the cost of them, and the path the original induction pipework takes going down from plenum entry though an ally vacuum operated valve (that i assume joins both paths at times) then back up and through afm its seems wasted and what a strange route to take so im thinking of doing away with the ally valve and using some silicon pipes and what not through afm into cone filter, then as i have no front fogs i have a nice hole for cold air induction too.
Question is has anyone else tried this, if so got any pics??

Thanks in advance....

Just use a Panel filter in the original airbox, as an induction one sucks in too much warm air to be honest

What are you hoping to achieve? If its more power, stick to the standard, but use a genuine Vauxhall air filter.

If its noise, stick a cone on end of whats there, keeping the bagpipes in place, though ensuring only cold air can get to cone (fabricate a seperate compartment)

This old chestnut again!!! I love duccie kits but only for the noise (louder than panel filters) little if any power gain. I bought a pipercross kit for £70 & it's on my 2nd Mig. Easy to fit. Members are divided on this one, some do some don't but i like 'em.

I got a decatted exhaust system on and have noticed more "pull" above 4k rpm so i thought it may help if it can breath in easier aswell...oh and i do like the noise too, lol...

Been speaking with a V6 mondeo owner (fwd ARGH lol) and his sounds great, all he done is made big holes in botom of airbox, and i have no fog lamps so have nice route for cold air pipe too, so thats that! nice and cheap to do, yeh!!

thanks for your advice on this anyway guys

I done what i wanted to do for £10.

The stock cold air pipe was so long in the box it must have made air flow a little difficult say the least so i cut this back, and drilled some nice large holes in the box for additional cold air.






Then as i have no front fog lamps i run 2x 75mm cold air pipes from the fog lamp apperture in the bumper, one to the underside of the inner wing into the exsisting hole, a very nice fit, and the other above the inner wing between that and the headlamp







Next was the fog lamp blank, after drilling lots of holes i went at it carefully with a stanley knife and created this!



From normal hight it looks stock



But from lower down all is clear for air inlet



Next i followed the stock cold air pipe and come to the conclusion theres a part missing from behind the grill as it just stopped dead! so i cut a section away to aid air flow into it



Then added another section so it now gathers air from both sides of the grill





seems a little "friskier" at speed but that maybe just wishfull thinking, does sound better though and still looks from the outside completely standard!

Excellent!

Nowt missing from your intake, mines the same.

I would beg to differ and reckon your missing the same part i am...  the end of the ducting is shaped for something to clip onto it, you can see little fixing tags that would hold another part in place and it terminates in front of the centre badge and at a right angle to the air flow too!!

I would lay money on there being another part to this, if not its a stupid design!!!

my 3.0l is the same. stupid design comes to mind.

Start a poll!     
I can't say I'v ever taken notice of any other cars but I'd reckon that all Vauxhall put there! 

[mark3]

Well i spose i must say i have never looked at any others either but it does look so much like something should be fitted onto it.....

still not to worry! lol

Im working in Brighton tomorrow (thursday) so il see how it performs during that run......

[amigov6]

Must admit i need to sort a cold air feed.

The intake is DESIGNED to be at 90 degrees to the radiator ... for a simple reason ... at speed the ram air will strike the front surface of the radiator but this causes resistance and not all the ram air passes though, much will move sideways, so going directly into the "mouth" of the intake, then following a smooth line to the filter box. If the "mouth" was directly forward it would only get ram air which would then have to turn 90 degrees to reach the airbox. By destroying the "mouth" the way you have, you have removed the line from the sideways moving air, and you have no "collector" for any ram air. if it were possible to measure the airflow to your filter IMHO it is now probably less than it was before !!

Having the intake at 90 degrees also means it won't collect rain and insects, of course.

in other words, youve bug-gered it.
