I have dynoed several chevy engines from 355 to 434 cubic inch. You spend the whole session running with NO air cleaner,Fine tuning, rejetting, any thing you can do to get every ounce of power out of your engine. When that is acomplished then you put the paper air filter on and do one more pull and very seldom does the rating change.THE ONLY THING A K&N FILTER IS GOOD FOR IS THAT IT'S WASHABLE. Otherwise they are waste of money if you think that your going to gain HP and fuel econemy.
