I have a 2004 3500 savana van does anybody no where i can get a after market cold air intake for it ,i cant find one online for this vehicle.also will a better air filter make any differance? Any help would be appreciated.

 

Me personally I wouldn't bother. Just upgrade the air filter.

 

I looked for an intake for my 97 1500. You would have to put one together with parts yourself. Nobody seems to make one specifically for a van. My air box is missing a chunk off the top side. I found an original in a junk yard for $65, that's what I will do. It is about $350 for a new box from Chevy.

 

does anybody think a $50 filter would make a differance opposed to a cheap one ??

 

Not really. Its a 20 dollar filter and I have a fram in mine.
If you need a new box, try a wrecker....
