The choice has a little bit to do with a multitude of variables.
First, dyno sheets show an increase in performance with air filters installed vs. no air filter. We did not do a comparative dyno run with K&N.
Aesthetics is always a consideration. ITGs offer high quality filtration with a "period correct" feel.
Perhaps the largest factor is the universal appeal of the ITG. They allow us to custom fit them to a plethora of custom intakes.
We're really happy with the way they fit on our custom high butterfly stacks.

This is definitely the "sharp end of the stick", as my engineer Dad would say, and a pleasure and priviledge to see...behind-the-scenes peek.

Basic question: would the engine make better numbers WITH the filters because the filtration media somehow creates favorable characteristics to the airflow...as in, the foam either straightens it out or swirls it up? Thanks, John/CT

i used to have data somewhere from another forum where a user tested it ITG/pipercross/K&N and from memory the data showed the ITG had the best flow/particle filtration of the lot- pipercross close behind.

curious about this too, i know the stock Rx8 intake for example there is even a fine mesh or something that straightens airflow etc so could well be?

Henry,

is this motor on an SC case?

thanks for posting!
