Induction kit should have all the bits in it you need to replace the airbox.

[keithyboy]

If it's the injected one it has an air filter box and another resonator box. If it's a 57i kit then, as popuptoaster says, it'll replace all of that and also have some plumbing for the idle control valve.

Somewhere in the depths of my photobucket account I have a pic of a fitted kit I think, I'll have a look.

[keithyboy]

Not as helpful as I'd hoped. Your airbox and the resonator box will be at the front RHS.

The idle valve was aomewhere hear the left hand strut mount I think.

[popuptoaster]

Different car and engine but the same principle, filter goes where the airbox would have been, proper kit will have a bracket to support the end of the hose and filter and any extra pipework required.

how i did mine...by doin the thing you don't want to do haha

[popuptoaster]

I'm not a fan of cone filters, most cars don't need them, the Cortina had one because there wasn't room for a stock airbox and it saved making one.

However they DO sound quite nice, although I have managed similar results just adding holes to a stock airbox. i had to open up the already fitted but blanked cold air feed in the airbox on my Volvo when i turned the boost up and it makes noticeably more noise.

[Copey]

aye, as Mr Toaster has said, not needed really, but they do make a good induction noise

Just chuck a nice K&N panel filter in the air box, most induction kits on standardish cars do very little.

If you're going to do it I'd follow Copey's approach. Personally I think it looks much better than mounting the filter straight to the throttle body, because you don't have to stuff the idle control valve somewhere.

Just use a hack saw and carefully cut the pipe as close to the resonance chamber (the black box after the air filter).

[Copey]

really is the easiest option, like you say don't need to relocate the ICV or anythin, just a couple of mins with a hack saw, or, if youre as lazy as me, angle grinder haha

[danburger28]

As above really. When I do mine, ill be chopping, and leaving the ICV in its proper position.Looks way better IMO.

This is how i did it on my old Granada, exactly the same layout. I extended the pipe with an off cut of black drainpipe and even used a downpipe bracket with a spacer screwed to the reverse of the radiator panel, didnt take long at all. The DOHC sound very nice with a cone filter too

[keithyboy]

The DOHC does sound good with a cone filter on it, I have to agree. I'm tempted to attack the airbox on my Audi with the spade drill bits over christmas to make it sound a bit more rorty now.
