I’ve been thinking about putting one on my car but I am a bit concerned after installing one on my wife’s ’07 Mountaineer with the 4.6.
It sounded great at full-throttle, but the rest of the time it was just too annoying to put up with.
The intake noise levels with any more that 10% throttle levels were just obnoxious. There was an extremely annoying drone between about 1800 – 2300 rpm which is right where it usually runs at highway speed, so anytime there was a slight incline on the highway where some extra throttle was needed, it would sound like there was a cow giving birth under the hood. After three weeks, I gave up trying to get used to it and put the factory setup back on.
I’ve been in many different cars and trucks with intake kits (K&N as well as others) so I know what they typically with do as far as sound wise, so I’m thinking and hoping that the Mountaineer was just a weird situation.
So on the LS, is it very noticeable all the time or is it like most cars with intake kits where it only gets loud when at full-throttle?
Any annoying droning under “normal” driving situations?
