I just installed my Thor cowl intake last night on my 96 XJ. It was an easy enough install and I have a few thoughts after driving it last night and to work this morning.
THE NOISE
I had read almost every review on these prior to buying and almost all said that its noisy for the first minute or two of startup and then quiets down, which is true. But every time I give it throttle it sounds like someone is sucking through a giant straw behind the glove box, and also a bit of a whistle at times! Yay! The only time it isn't sucking loudly is when coasting, at idle, and wide open throttle - which makes the 4.0 sound beastly, but is also really loud itself. My wife may never ride with me in this Jeep again, she didn't like how loud the Jeep was before this intake was installed.
ENGINE TEMP
This Jeep has a 195 t-stat and always runs a hair under 210 in everyday driving conditions. I am now closer to 200 post cold air intake. Not sure how it could affect it that much but it is. I watch my gauges like a hawk and immediately noticed this. Nice surprise I guess?
The reason I installed this was to free up space for a secondary battery but I don't know if I'll ever get past the noise. Any suggestions on what could be done to reduce the sucking sound or do I just accept it or remove it? I read something on another post about applying some kind of sound deadener inside the cowl?
