I wouldn't waste my time with a clamp on the filter itself. I just beat a piece of 4 inch exhaust in, run a ring of silicone around the seal stick it on and mask off the filter with a piece of cardboard and spray starting fluid around the area and see if the motor idles up for leaks. No problems yet, and seems alot simpler and the clamp could fail. Jdecker, I removed some parts and ground on the plastic a while until i got it to fit like I wanted.

My filter has been directly attached to the intake tube for almost six months with no problems. Used the stock clamp and roughed up the filter neck with some sandpaper to give it some bite. Never had a reason to mess with a piece of pipe.

77, I noticed that some tubes are shorter, especially the earlier ones. Mine is almost too long. I had to wedge the filter against the little tab that sticks out of the batter box to keep it where I wanted it instead of against the inner fender wall. If he has the longer tube, it works great like mine. If he has the shorted one, it usually takes a tube (with a 120* bend in it).

Well, I know they make black, so that's what I'd get... Just curious.
BTW, that's a good idea. I had lots of bugs caught in mine after driving through south FL a while back (Love Bugs). I would've put some of that on had the thought occurred to me.

One thing I have noticed with the 6637 mod is that it allows much more hot air to be pulled into the turbo. Since there is no shroud and the intake duct basically becomes useless, has anyone noticed any problems from this point of view? It's certainly important to keep dust out of the turbo but the turbo loves the cooler air as well. The 6637 mod also eliminates the air ram effect provided by the stock set-up. Living in AZ were it is 110 through the summer I am just curious if this mod would help or hurt the truck's performance.

mshostek, this has been debated and tested many times. The filter definitely gets warmer air when stopped or driving very slowly. When you get up to even city driving speeds, the air under the hood is much cooler. Also, "Ram Air" with a turbo doesn't mean too much, wouldn't you agree? However, the Zoodad mod with the stock air tunnel still in place next to the battery would help provide cool air to under the hood when moving. I haven't done that just yet, but it will get done soon. I want to put a screen over mine, so I've been waiting until I get the time to make that part...
