Ok first this is my first V-tec engine and I have heard the term "screaming v-tec" before, so I got my new ram air intake today and put it on connected everything like I always do, when the car idles you can hear a "grumble" from the air intake almost like something vibrating, i checked everything to make sure there was no movement, So I got onto the highway and hammered on the car to get the v-tec to kick in which I can hear kick in, But is the grumble/vibrating noise normal on v-tec's with aftermarket intakes?...Sorry if this was posted somewhere else i tried looking and found nothing.
