So you haven't taken my advice on the trip to the doctors.....
Yes - engine components get warm when a car is driven.
No Suprise here then.....
Yes - warm air does rise in a stationary engine bay.
Not Rocket Science.....
Companies like that develop products for a wide range of cars and simply adapt them for different applications.
Not true, every single AEM, K&N, BLITZ & HKS filter kit is developed for each car including extensive testing & dyno runs. Take a look at K&N's website for the details on each application which include full colour instructions & in many cases dyno graphs.
Excess heat escapes the engine bay as the volume of air that passes through the radiator and the open wheel arch areas (especially on the O/S of the EP3) cause such a high volume of airflow that the air under the bonnet is constantly replaced / recharged. Your statement that warm air doesn't escape from the rear of the engine bay is ludicrous, back to that cough of yours again
.
Radiator positioning is obvious for many many reasons as is the fact that i'm not a car designer and you most certainly aren't an engineer.
I agree there is lots of marketing bollox out there pedalled by lots of different manufacturers (most of which ABP don't have any dealings with), we believe facts that companies like AEM, K&N etc make publically available which include power graphs etc and we also independantly dyno parts ourselves on our cars to back these claims up. There is also LOTS of 'internet forum keyboard wannabe engineers' preaching absolute bollox with little or no experience or knowledge of the topic, as i often say 'A little bit of knowledge is a dangerous thing'.
BTCC, WTCC, DTM, WRC & FIA GT are teams with limitless budgets and all will inevitably use specific designed intake kits as they can do things that on road cars are simply impossible or impracticle to do. How many EP3 / FN2 owners do you know who would be prepared to run an air intake in place of a headlamp or cut the front bumper to pieces?
Stunning DTM pics but how many road cars will spend £15k on an intake / front bumper kit? Horses for courses and you get what you pay for right?
You will be pleased to know that we have supplied very few PIPERCROSS VIPER kits for CTRs as most people choose to go for AEM etc
Manufacturers are restricted on using the common black plastic airbox system for a number of reasons including strict sound levels, cost, space restrictions, multi-country use (whats good for Africa isn't so hot for Sweden) and others. But specialist manufacturers including Westfield & Caterham still use open filters.
Interestingly take a look at the filter used by Roger Clarks Gobstopper, quite possibly the best Impreza in the country and 2008 Time Attack winner, you guessed it an open K&N cone filter

Now get to the doctors before that cough gets any worse
