Re: Cold Air Intake Interest??
I've owned my Genesis for about 2 months, and in that time I've tried to remedy this problem on my own - I didn't care for the results, but maybe someone else will use the information.
In my desperation to actually hear the V8 lurking under the hood of my car I decided to take it upon myself to change the intake. I initially removed the entire filter housing, the "bottles" on the intake pipe and plugged those holes with
plugs used for residential plumbing and hose clamps; I also used a generic 4" filter fitted directly to the MAF. Ideal? Nope, not at all. It was not a viable solution because the weight of the MAF and filter along with nothing to support them (aside from a rigged up solution using a massive hose clamp) meant the whole assembly hung very low, to the point of reducing air flow. As for the increase in performance, there was no appreciable change aside from the sound, which was nice at WOT but terrible at partial throttle. Maybe it's because I'm used to driving a manual transmission, but it sounded pretty bad at partial throttle. It sounded fine in manual mode, until you bogged down in X gear, remedied by shifting to X-1 gear.
Next up, I put most of the filter housing back together, save for the flap assembly at the bottom of the big filter housing and the green post filter in the top section and took the 4" filter off the MAF. This, of course, alleviated the assembly hanging problem, but there was still no performance increase and it still sounds goofy at partial throttle, just quieter.
All in all, if you're curious what it sounds like then you can spend 25 minutes and $25 on a generic 4" filter or just take some parts off for free. The above solutions still runs through the stock air intake hose so I'm sure that affects the performance and sound, but I'm not sure to what degree. Without putting a PVC intake or piecing together an aluminum one, I'm not sure what the change would be. That still wouldn't change the partial throttle sound, which is a function of the transmission and shift points.
To each their own, this was my experience.
