Title: air intake system question
Post by: navmk4gti on 18 August 2009, 21:57
does anyone know where i can get an air intake pipe which will allow for me to place an open air filter ... i just need the pipe.. or does anyone know the sizes needed to make one e.g diametre .. angle of bend....  :smiley:

Didn't you rescue the ebay carbon kit from your car?  :undecided:

Post by: navmk4gti on 18 August 2009, 22:20
yep that is all untouched just my intercooler cracked thats about it mechanically wise.... the pipe on that ebay stuff is a flexible type im looking for a alloy pipe so better cold air

want to get all this bits and bobs done before i get a remap  :evil:

do you mean you want one of the long induction kits without a filter? You can get them off the bay for less than 50 quid with a filter
Title: Re: air intake system question
Post by: navmk4gti on 18 August 2009, 22:44
yh but i dont want one that makes the filter go behind the front bumper as i have heard about water getting caught up in it so aint taking that risk...  :smiley:

was thinking getting pipe made or buy one and then stick a pipercross filter at the end and get a heatshield made for it.. iv done it before in a clio  :embarassed: that was easy tho just a 90degree bend .. looking at the mk4 no space for errors   :nerd:
Title: Re: air intake system question
Post by: tg1 on 18 August 2009, 22:52
the water would have to be just under the headlights to go up the filter, i also had one on my yaris ts and that was less than a foot off the floor and never had any probs with that. mind you i never went through a ford, deep standing water.

i'd say pop down you're local exhaust place and see what they say, or get the ebay one and cut the pipe back till its where you want?
Title: Re: air intake system question
Post by: navmk4gti on 18 August 2009, 22:55
the exhaust place is a good idea.. i wanted get it done while its in the body shop tho... ill go and measure it up then that  best can do i think.. see how it goes.. few guys on here said they have had water probs.. but each on their own  :smiley:

the diamtre standard pipe is 3" isnt it????
Title: Re: air intake system question
Post by: tg1 on 18 August 2009, 23:05
might be? could you not get a standard airbox and chop it up so you can connect the filter to whats left of the box that would plug into the maf?

thats too short already thought of that need a pipe that will allow filter sit close posible behid the drivers headlight

exactly lol  :laugh:

hence my prob.. ill give the exhaust place a shot theyll get something done for me.. by sounds of it no1 has tried or acomplished this if i am the first one you know there is hope for us brave ones  :grin:
Title: Re: air intake system question
Post by: topher on 18 August 2009, 23:26
so you want a filter housed in a heat shield on the left (as you look at the engine) then a piece of alloy pipe going over the VERY HOT intake manifold and around the VERY HOT engine and into the maf?

sorry mate but thats a crap idea :grin:
Title: Re: air intake system question
Post by: navmk4gti on 18 August 2009, 23:31
huh ..oh sh!t sorry i meant behind passenger headlight  :laugh: :laugh: :laugh: :laugh:

you got me thinking wtf!!  :laugh: :laugh:
Title: Re: air intake system question
Post by: topher on 18 August 2009, 23:34
ah i see.. well you have a battery in the way for a start so unless you relocate that then you're back to the original airbox position surely? there are tons of kits available to put a cone filter there
Title: Re: air intake system question
Post by: navmk4gti on 18 August 2009, 23:36
batter covers coming off for starts... and i can squeeze the filter in already tried it in the garage today its just the pipe work to get it bang on is tricky.. if its off then its all fooked
Title: Re: air intake system question
Post by: Ivor Mk4 Turbo on 19 August 2009, 13:41

On my old Pipercross VIS kit, the filter was more like in line with the lower valance grill, than just below the headlights!  ;)

i don't either especially as the conclusion from many a dyno run suggests that a decent panel filter gives about the same results but without the fear of destroying your engine!!

I prefer the roar that the induction kit gives - but if it can knacker the engine - time to break out the angle grinder again  :laugh:

Seriously though - I dont think that water could travel up the amount of space and the bend in any great quantity - its not an inverted snorkel at the end of the day lmao

This is mine http://cgi.ebay.co.uk/NEW-99-04-1-8T-GOLF-GTI-JETTA-A3-Cold-Air-Induction-Kit_W0QQitemZ250475663859QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item3a518351f3&_trksid=p3286.c0.m14

Unless you literally drive through a swamp with it, I cant see how its any different from the one wrapped in carbon fibre other than the filter is exposed - there is just as much chance of water making it up into the carbon one as there is a pipe that leads down to the same place as the filter on the ali one
Title: Re: air intake system question
Post by: T_J_G on 20 August 2009, 13:15
Not really the  suction can pull water from the bottom of the intake itself up the tue, but the suction for the 'carbon' one ends after the cylinder it's in. If that makes sense.

Nonsense.  The carbon filter is situated in the stock location & uses the same feed as the stock airbox i.e.  through the main front grill, so whether the filter is enclosed or not, is completely irrelevant to your point.  Your filter/air feed sits near enough level with the N/S lower valance grill, which is too near to the floor in my humble opinion.  ;)

i have same one as ivor and he is right the pipe of the carbon filter box just replaces the standard airbox nicely... love the sound.. but im looking to make a custom one now... you have balls to take the risk of putting a filter that low to the ground  :grin:

Don't mean to pi55 on ur parade, Dalo, but just don't want to see another "I need a new cylinder head" thread. ;)

You can buy 'water jackets' for the low down filters, but I can't see how they're not going to restrict cold air getting in.

P.s. Believe me, the turbo's suck in more powerfully than a porn star, lol. :D  High boost cars can cause stock turbo inlet pipes to collapse! ;)
Title: Re: air intake system question
Post by: Dalo Harkin on 20 August 2009, 23:44
Noted mate - but what im saying is rather than spend more money on the one you have, I would rather for now just put a smaller pipe on so that the filter doesnt hang in the wheel arch and keep the filter just behind the battery (for now)

Title: Re: air intake system question
Post by: Dalo Harkin on 21 August 2009, 00:11
All the filters are basically the same when it comes to the non foam ones really, even halfrauds do their own lol
I know I have some odds and sods of induction bits in the garage somewhere (goes digging for pipes)

ebay £39 cold air filter kit the one that sits in wheel arch , went out a min ago , gave it a good bit of abuse when i got back i felt the cold air pipe and it was freezing and the inlet mainifold was nice and cold , well happy with it  :smiley:
Title: Re: air intake system question
Post by: Dalo Harkin on 22 August 2009, 08:40
thats the one I have but after seeing IVORs ebay thread one - i will be getting that at some point as there is no space behind the battery to run an ali pipe and a filter.
not chancing borking my engine  :sick:

I love the induction noise it gives off on the wheel arch one though  :cry:

which airfilter have you both got again Ivor and Nav?

ive got a evo motorsport airfilter on mine, cost a bomb and you can here it sucking nicely, but i want more of a roar, as if there is so mich air beeing sucked up when i put my foot down like you get on some turbo cars.

doese it sound anything like that, or is it cars with biger turbos that have that?
