Induction kits HELP

[benji mk2]

Any one got any advice on induction kits for a 1.8 8v? Do they just fit into the bottom of the metering head?

Induction kit? mk1? are you sure you dont mean a panel filter?
As far as I am aware they are not made for the mk1.

Ive tried getting hold of a k & n induction kit for my 1.8 8v, everywhere ive been has told me they dont do them for mk1's!
Does n e 1 else know otherwise??

This is the thing, i cant see how it can be done, but i see people selling them? Whats the best way to optimise the air flow on the mk1, or is it just a case of stickin in a panel filter??

 cheers for your help everyone,

I have a K&N panel filter and a modified exhaust system. This is the key to unleashing a few extra ponies, when you first start doing power mods to the engine.

Cheers adam,
  The engine already has lots of head work (gti engineering) a 4 branch and ported intlet maninfold. But i was a little unsure about the air filter side of things!!! I just hope the bloody things gonna work, as im in the middle of transplanting into the car!!!!

I removed the duct from the airbox to the back of the front valance.

(Does anyone know what the purpose of the duct terminating there is ?)

Then I drilled a second hole about 2" dia next to the existing inlet, and installed a Piper X panel filter.  The result seems to be that I can now approach 100mph, when previously things seem to stop happening at about 85/90.
No quicker off the mark though.

I was considering fabricating a scoop/funnel out of glassfibre, cutting a slot in the front valance, and mounting it there, connected to a new piece of ducting to the box.
The idea being that induction begins to be forced the faster the car is travelling.

Is this advisable ?, or is this bad science ?

to draw in cold air as its denser than warm air & hence more O2.
just a thought but if the airbox was sealed and empty with a bigger intake duct from a cold air supply (not forcefed by air pressure then an induction kit upstream of the metering unit it could possibly work.

or thinking about it put the induction kit before the air meter box which would be empty and sealed.

The duct is there so it can draw in cold air (away from the engine) without being forced!  Because of the metering head it is not advisable to relocate the intake pipe to somewhere like behind the grill headon to the wind.  This could cause damege to the meter and would probably make your car stall at speed, the metering head would be forced open most of the time and won't regulate anything at all, it would prob just stay open all the time.  I had the same idea as carrie once with the sealed airbox, additional pipe work and a 57i kit.  It would look ok if you could find it all a good home but not sure of the benifits.  If you were to do anything, at most, you could buy the k&n panel filter (or similar), drill a couple of 2" holes at the bottom of the box and add a nice pipe blowing cool air in its direction but nothing sealed or force fed.

when i said sealed i ment there is drainage holes in the bottom of the air box which if using an empty airbox with a filter before the box would result in unfiltered air getting in, i did not mean literally seal the air box.
to ensure the metering head clamped down correctly an old air filtre with the element removed would also be needed to seal round and ensure it clamped.
