Yeeah....But then you CAN hook up a kiiler lookin leaf blower to it and force the air through all those turns.....Right ??

Awesome...TY hydra....

 

I finally did this mod to my D. It was actually a PITA. On my '02 with a 5.9L, there is very little room between the radiator and the passenger headlight due to the a/c lines. But, with a little enginuity (and 3 beers), I made it work.

For those of you with this mod... do you have any problems with automatic car washes? I have a feeling my engine would not appreaciate an internal bubble bath. (I have the oiled air filter, but it may be no match for hot suds).

 

even if it does restrict the flow a bit i might make one for it that i just put on when offroading and take off the rest of the time.

 

someone mentioned that they would just shut off the engine while in the car wash so that it wouldn't suck in any water

 

Beer rocks!

Anyway, I never shut mine off and in fact I even hit the gas a few times with no issues. However soap would break down the oil on the filter so maybe it would be a good idea not to hit the gas when the soap is fly'in.

 

Personally, i use the old fashioned way of getting out of you vehicle and doing it by hand with the foam brush and the spray gun....no issues yet! (sorry had to be a smartass)
