hi everyone and MERRY XMAS to you all. i have done a quick search and havent seen what im about to ask pop up.

right, i have a green cotton filter in my standard 6 airbox after fitting this some time ago now i have found that the car was and is more responsive when you stamp on the loud pedal.

then i had a thought ........ lets see if i can make the old girl suck a bit more?? what i did was remove the small secondary air box and capped off the hole for it. I then removed the main pipe from the top of the air box leading to the slam panel because in standard situe i noticed the there is a gap between pipe and box which must be about 15mm.

anyway i pootled down to my local exhaust place and made a stainless steel sleeve which i flared to fit tight into the top of the box, we then spot welded it into place to make sure of no movement. We then flared the other end so that it would fit extremely tightly into the existing cold fit and buzzed a bead of silicone round to make doubely sure it was all air tight.

Now we have no gap and a very air tight feed. when the car is ticking over you can feel the air feed sucking, and when you twist the throttle it really sucks alot of air with a very subtle induction kit noise. so i took the car for a spin and hey presto even more response when you hit the loud pedal.

But today after a conversation with a fellow forum member he suggested cutting a hole in the cold air feed roughly where the bit sits closed for even more air. his reason of thinking was due to the feed pipe being situated under the grill.

IMO i think this could be an excellent idea but what do you all think? as said above she already sucks alot of air with the mods i have made to the box. If this will aid induction anymore then im game!!!!

sorry for the essay, Im not really a believer in iduction kits really unless you have a proper enclosed one with good air supply e.g down by the fog light. However with our terrible english weather i would be scared in sucking up water.

Thanks in advance guys Smile

This is weird because I cut an opening in my existing cold feed above the grill today, can't really say it's made much of a difference but I have been thinking about ways to improve the standard air feed recently, not sure what you mean by the small secondary airbox though

as you stand looking over the engine bay so the airbox is to your right look down and to the left of the air box and you will see a small secondary air box. i assume by routing the air on a longer journey it quietens the sound of induction and doesnt breathe aswell. have it gone Smile

Done the same to my airbox,removed the resonatorWink
Also I was thinking about the forced induction feed,so I have cut the end off the snorkel intake on an angle just above the slam panelSmile
So now once the cars moving air should hopefully be pushed into the airbox between the bonnet and grille,instead of it just being sucked from behind grilleBig grin

not sure about the 306 but on the xsara there are some holes in the slam panel directly below the mouth of the scoop which will obviously disturb the airflow coming in thru the grille, so i screwed a bit of stainless plate onto the back of the scoop where the mesh screws on to deflect the airflow straight up into the scoop, and there were 4 holes about 10mm diameter in the scoop where it goes down the back of the rad, i taped them up to stop it sucking in warm air, and finally i made a custom airbox out of aluminium, very similar to the OE box but to fit over a K&N 57i and shaped to send the air spiralling round the filter instead of straight onto one side of it.

seemed to make a big difference over the open filter, but i did tighten the throttle cable at the same time. also made it nearly as quiet as the OE box, which disappointed me. it's off now though, i missed the noise and don't see the point in cold air feeds when it's -7 outside LOL i'll be putting it back on when it warms up a bit.

As I said not sure whether it's made much difference as i also tightened the throttle cable at the same time too, but it's definitely worth giving it a go, car is running sweet at the moment!
