DIY Filter

[bigtrain]

I have an early 99, where can I find a 4" exhaust pipe witha 45 degree angle to fit between filter and intake pipe?. Also what is a zoodad?

pep boys, exhaust shops, i used a 4" abs dust collector pipe.
a 3" pvc pipe will work but was too restrictive for my truck even running stock.

zoodad is a small hose that goes from the air box region up to the frill area near the radiator , IC area.

Search this site for the Zoodad mod. I bought mine on ebay. disregaud prvious sentance

Rather than start a new thread...
Anyone with a e99 have any issues with the DIY Intake paper filter and the fender hole? I'm worried that the filter will get damp or completely wet thru that fender hole in a downpour at higher speeds.

I don't know where you read about the zoodad mod, but it has nothing to do with a hose of any kind. The zoodad mod is just cutting a hole in the header support to remove the obstruction from the end of the snorkel on the OEM airbox setup.
samiam- no issues with my 6637 getting wet, but I don't drive in rain like you prolly get. A filter cover from Pete (TruckMods) will probably help keep it dry to some extent.

OOOR
in the case of most users who got rid of the POS oem box
it is cutting a hole next to the radiator/ intercooler letting fresh air in from the nose of the truck . there is a fancy version of this sold on summit
for 49.00 but never saw anyone use it. when I say hose i mean a 3~4" dryer type hose to direct the air in if you have a sealed unit.
..or you can leave it out

here are some directions if you need them ..have to copy and paste the pic links
