Hello,

I'm after some advice on a better air induction setup for my new 75 3.0V6, hope you can help.
At the moment it has an open 'cone' type pipercross foam filter attatched in front of the MAF etc, I have part of the original air feed section in place to direct flow to the filter; however I've never been too sure how effective these open filters are considering how much unwanted hot air gathers under the bonnet.
I used to have a BMC CDA filter on my old 155 which worked very well and ensured that only cold air got to the filter. Are these or similar available for the 75V6, or has anybody any other (cheaper) suggestions?

Many thanks

Cheers Purple, but wanted to get away from the 'open' type of filter as they do tend to suck up a lot of hot engine bay air, guess a CDA is my only option really. Better start saving...:p

Hi Glen, I was always having similar thoughts to you with regard to airfilters/boxes but its tricky to say what is best. Admitedly when you are stationary the heat soak will make it worse off but when moving the airflow through an engine bay is actually down due to the shape of cars so the coolest air is always at the top. However on my escort cosworth I had I used a cone filter and tried it on the rollers. 9bhp less than the standard airbox with panel filter. But on my 75 the airbox was useless. and on my 33 race car it appears to run better with out the airbox HOWEVER on our TS 75 we used the airbox with a k&n panel filter as with a cone filter it made no difference to power. The final thing we did was to modify to cold air feed to the box. We put an additional feed in the side to ensure good volume of air and the standard feed we cut right back and fitted flexible ducting to both feeds from the fog light appature as well as brake ducts and on the rollers the bhp went up by 3.5bhp!!

Cheers for the reply, I reckon I'm gonna source another cone filter (that actually fits!) get some better cold air feed hosing from the fog light area and then fabricate some kind of aluminium heat shield to partition the filter from the rest of the bay.
P.S. your red 75 looks identical to mine! apart from silver wheels... nice!:cool:

Interesting, this one. I suppose I'm now glad I stuck with the standard setup on my TS. I wonder how much better a K&N panel filter will flow above standard.:rolleyes:
