I installed a AEM Short ram air intake on my 99 lude. It was brand new and $30 bucks from a freind.

Installed properly plugging the vacume line on the intake manifold and so on.

It is loud as sh*t.........really. Is it supposed to be?? Definately when v-tec kicks in. I've installed AEM intakes on my old civics all the time...they were never this loud...Is it just the H22 with the intake that makes it so loud??
