I have a vararam on my car and have installed somewhere around 10 total at the last few FiveOJoe's mod parties. The install is not hard, you just need to take your time and install all of the screws around the duct openings. Four to five hours for a first install is not unusual, because figuring out how to do it, is the tuft part. Once you know the drill, under two hours is the norm.
As to filters to use in it. The foam filter will work just fine, if you are willing to spend the time every 3,000 miles and clean it out. If not, get a K&N, most will not notice the difference.

Can anyone comment on the HP increase. Has anyone dyno'd before and after?

You really can't measure the effectiveness of the vararam on a dyno, the best way is to look at differences in 1/4 mile times and speeds. Lots of threads on this site and you need to decide for yourself.
There are lots of good aftermarket filters out there, the differences between them are not that huge. One of the reasons I chose the Vararam was I also liked it's looks.
You may want to consider a smooth surface air-bridge since the Vararam has a tendency to move upward some during driving and the standard duct can dig into the under hood insulation a bit. Good Luck on your decision. :thumb:
