In this Pic, is there a cold air feed in the fake brake ducts?

is that not where his filter is hidden

You mean like this one on mine ?!

Looks a bit restricted there, needs opening up to get the real benefits. However, not many people would like to start carving their beloved up

Restricted - you are kidding aren't you ?!! There is no better way to have the filter, it's away from all heat sources and is directly at maximum air pressure. It took me a lot of playing around with to get the hoses, pipes and position right but when i hit it, boy did i hit it right ! It's eliminated that nasty low down flat spot that i feel all ZS180's suffer from and it now pulls incredibly. This is the 1st ever filter set up i've done on one of my cars (everything from Cosworths to 205GTI's) where i can genuinly feel a benefit. This is the hose set up i have

No, not kidding!

I have worked with induction systems on 750 superbikes and BTCC cars, so know a thing or two!

What I meant was the inlet area, there is more to gain by allowing the air to get in directly to the filter in question, not just the small gap there. I was not knocking you at all.

In other threads I have explained this in greater detail and over on XPF, so know a few things on the subject. The 180 is probably one of the worst cars I have had with regards induction and available space for a road car. It is all about compromise.

You are so right about being the worst car for induction - that's why i have played around for so long getting this set up ! 1st position was filter directly onto throttle body. Felt sluggish. 2nd was an airfeed from inside the arch to the filter connected by a 90 degree pipe on the body. OK, just like standard. Then i did this and voila - success !!

I appreciate your skills in this field and all comments are welcome, after all if it gets us more power then that's great ! Personaly though, this has proved to be the most effective method i've tried on a ZS180 ! Just for the record, it sounds awesome too !

Oh, one other thing ; that photo was took before it was 100% fully complete. It now has a small mesh grille behind the opening sprayed matt black to deflect stones. I also have drilled a series of holes in the lower part of the inner wing that connects to the front bumper to prevent any water building up - which could be catastrophic ! The filter is positioned further back than it appears though !

I've spent hours with the bumper on and off looking for that last millimetre! I have stopped at this set up for now, and made a marked difference from the inner wing intake I had. I will persevere!

Can't really tell from that picture what you have done to be honest except for removing the fog lamp !
