[s-cars] Cold Air Intake

Tue Oct 4 08:56:40 EDT 2005

Cut and paste from the article...

"Sure, the intake to the airbox wasn't causing all that much of a flow 
restriction on the Audi. You could say that the negative boost lurking in 
the airbox intake snorkel was only a medium size critter - nothin' as big as 
the bugger discovered in the airflow meter, for example..... In fact, of the 
flow restriction of the standard intake, the bit before the airbox was 
responsible for only 28 per cent of the total. Still, if it could be got rid 
of..."

I was not saying the entire intake system was perfect, just merely referring 
to the intake box. Sorry if that lead to any confusion.

My concerns with a K&N filter stem from the fact that they can let in MORE 
particles than a stock filter. These can confuse, or even take out, a MAF 
play havoc with a nicely balanced compressor wheel and clog an otherwise 
decent intercooler...

YMMV, etc etc.

I am not trying to say don't try to improve, but just to state that what you 
have ain't all that bad.
