Has anyone else spotted that stupid cone inside the top part of the original airbox? it feed the air inlet tube coming out of the air boxIt twists out and is now lost somewhere in the shed. Probably is used to quiten down the induction, and probably does nothing for the engine if removed, but makes me feel better knowing it's gone. Also pssst noise is a bit louder when you dab the throttle.

Anyone else modified their airbox? Considering making bigger holes in the bottom.... cheap mods this weeknd!

Did it make an improvement ???

I'd be careful about drilling holes in the base of the airbox- it pokes into the inner arch and will quite readily suck up any water that get splashed up by the roadwheels!

I did take it apart at the weekend, and found that water ingress would be a problem. Wet filters and airflow just don't mix.

Thinking it over...... will think of something to do. Probably wont make any difference, but mentally will feel faster!!

Is this only on the 1.4 engine? I can't remember what it looked like on my 1.7 :oops:

The airboxes are in the same position, and the chassis is the same. But couldn't tell you for sure.

Better ducting would probably be best. Saw brake cooling ducts in demon tweeks catalogue.

If you hooked these up to a ducting tube leading to the airbox / filer, it should give you good cold dense air. Saw polished metal duct tube on a honda, they look really well under the bonnet. Lets face it, you're not doing it for the perfomance gain.

I do believe the standard airbox has a "cold air feed" i.e. one that does not come from within the engine bay... it actually comes from inside the passenger front wheel arch smile.gif

There ... saved you some money... ja_cool.gif

Yep, you're correct. Got down as far as that last weekend. It probably works fairly well, but is dull black plastic. I've braided a lot of the coolant hoses etc in the engine bay (extra 5bhp there!!) and wanted to contiue the theme.

Something similar to this, but not attached to the filter maybe:

Be careful with braiding stuff... unlike rubber its very abrasive and will "file" its way through other materials, ally, steel, rubber, plastic, electrical wires very quickly due to vibration / movement. Not a problem on show or competition cars which are maintained on a very regular basis when compared to a road car...

Agreed.

If you are going to braid, then buy braided hoses. Not cheap, but they come with an inner braiding laminated between the rubber.

For power increase (which is neglible) you may be better off using thermal wrap on the manifold and down pipe.

Again, not cheap and a bugger to fit, but will reduce under bonnet temperature.

OOer. Cheers lads, didn't know that. They've been on the car for nearly a ear now. I'll check them at the weekend and see if they're causing damage. They're quite a tight fit so movement should be neglgable. I'll let you know...

I've had braided hose "eat" into - ally fuel tank, dump valve, header tank and electrical wires... you would have thought I would of learnt by now wink.gif

Also found a nice deep grove in one of my power steering pipes just above the rack... worn from 3 mm to less than 1mm... be warned - not sure what caused it yet but its being replaced anyway...

Ditto part of that. The top of the oil seperator has a lovely groove in it caused by the braided water expansion pipe rubbing on it

I've put an air suction mainfold like this: http://www.bonalume.it/index_eng.asp?a=det...glio_prod&id=17

Take a look at the link, it explains well why the cone is useful.
