Re: 240hp Abt A4

I would never use a cone air filter conversion. The reason is is that
first, I have a crude ram air setup through one of my front headlights.
Second, you want to pull in cool air, not hot. I had a chart from European
Car that gave approx. power losses due to temperature. Anyone who may feel
hp increases, may actually be feeling more instant power due to a
shortened intake due to a more immediate supply of air. At top end, more
power will be lost. In my car, if I put in a cone filter, I would expect
nothing less than a 15% decrease in power because of the turbo and exhaust
manifold's close proximity to the air filter area. BTW: I did say the word
"may".
