Will this work on a crd with a v6 airbox?

That's specifically for the V6 airbox - circuitously puts the air inlet back down low front, similar to CRD airbox inlet......................

ah, so i guess nothing gaining with this if using it in a crd with a v6 airbox? Meaning just sucks in water too?

0311_DOC is putting it on his CRD. Maybe he will post pics and results as soon as he gets it installed...

That's too funny. I wonder if they are going to call it the CRD air box mod??? Maybe we could all just trade each other air box lids and update our sig lines. Somebody better tell them the v-6 airbox breathes sooo much better.......

well if it still eliminates the water issue it would still be a upgrade. it looks like the inlet / is wider as well... not sure though

Diesels need more cold air which means more oxygen per square inch, which means a better combustion, which means more power with less fuel, which means better fuel economy.

Run the Amsoil drop-in filter and you will not have any problems. Amsoil is made for the elements and the water molecule is bigger than the filter media. Plus, Amsoil uses nanofiber technology which does not absorb water or moisture. Therefore, the filter maintains it’s integrity.

The intake scoop is roughly 6" x 3" and goes down to a 3" diameter.

whats the stock crd? never measured it. if anybody knows offhand.

if i can avoid water altogether that would be better then having a soaked filter. While the Amsoil drop-in may not let water into the engine it does in fact get soaked... letting less air into the engine. It will stay soaked for some time. Thats why i am interested in the v6 box

I know they say it wont get soaked but it does. :evil:

found out the hard way. I was thinking the oil would help to shed the water... but it did not.

0311_DOC: did you have any good results with the v6 box not letting in any water with the intake?

Airflow is dependent on inside diameter (cross-sectional area) of ducting, plus length and path of ducting - curves, bends and corners are very restrictive to airflow, as is overall linear length of ducting between inlet and airbox - 'nuther words, the inlet opening may be only 1' from the airbox, but at the end of a 4' section of bent, angled and curved ducting - the straighter the path, the better the airflow - one advantage to bends is they function as primitive centrifugal filter - fluids* prefer straight-line flow due to inertia - denser the fluid, the more difficult to navigate curves'n'bends, particularly in the vertical plane, which adds gravity assistance - air moves around the bend, water slings out - a small orifice must be placed at bottom of each bend to prevent water accumulation therein

*Fluid refers to any substance that can occupy volume of any container without changing the shape of that container, liquids and gasses inclusive - and don't gimme no squat about no balloons, neither! - that concept refers to any substance that alters the shape of the container, such as food and yer wife, eh!!!!!

Actually, it would be more proper to call that a "hybrid" (choke, gag) setup - V6 airbox with a CRD-type grille inlet.

It would look to flow better than the OEM CRD setup - no oddball twists and turns, and does away with that funky rectangular opening to get past the headlight - all open 3" hose.

Big fault with the original CRD design was anything that came in around the gap in the headlight and foglight - rain, dirt, bugs, etc - had a short straight shot right into the airbox, and no real change in direction, so straight up into the filter - airflow coming into the bottom of the airbox sideways as it did IMHO actually stirred up any gunk in the bottom so it had a better chance of getting sucked into the filter.

With the 180 change in direction to get into the V6 airbox opening, and then the inlet being directed toward the bottom of the airbox so it has to do another 180 to go thru the filter - looks like it would definitely stand a better chance of keeping extraneous gunk out of the filter and a longer service life than the OEM CRD design.

Cold outside air and better airflow/ram air effect than the original CRD design? I'd say that's a definite. Better at keeping water/dirt/bugs from getting to the filter and causing an early demise? Could be, design looks good, but that big open scoop behind the grille down low with no screen/baffle.... Fording deep water or a stream? Same fault as the original CRD design, way down low at the grille, better chance of sucking in liquid.

And the 64 dollar question - per use on our CRD's, does it correct the faults of the original design as far as water/dirt/bugs ingestion and filter service life, and does it offer any real advantages over the V6 airbox setup some of us have went to? Guess only time and experience will tell on that one.

For now, I'm happy with the V6 setup with "swiss cheese" holes on the fender side - good airflow, filter lasts a long time, no "ring around the tub" in the bottom of the airbox. But I'll keep an open mind and see what people experience with this setup.

Haven't hooked it up yet... just recently got all the components.

that was my concern initially. so i am wondering if the LTT scoop is going to help or hurt doing the V-6 airbox mod. I also would like to see your swiss cheese holes to get an idea of what it looks like and debate doing that to mine.

Will this work on a crd with a v6 airbox?
