Air Cleaner Insights, 914-6 Correct Options

[DennisV]

Is this air cleaner correct for 1970 914-6? Am I missing any components?

I went through the other air cleaner threads I could find. A couple things about our plastic one that seems curious when I compare it to the photos I'm finding of others identified as 914-6:

1. No clips or inlets for cold start fuel lines
2. Large to small outlet plastic fitting

Thanks.

P.S. I am unclear about the fittings. My best guess is the small single port metal one is a water drain valve and big plastic one with two outlets is oil breather? Not sure how to connect either.

IMHO that is not a 914 box. It is a 911 box. The snorkel appears to be correct six but there are some 911 snorkels that go to the same side (congrats either way, these are very difficult to find).

Having said that, there is no reason that you could not use that box for 914-6. You will need the correct carburetor buckets with the long version clips as shown in the thread linked above , post #7. You will have to drill holes between the stack holes for the Weber vents.

Hate to disagree with anyone as esteemed, learned and gentlemanly as Clay, but all six boxes I have seen have the individual stack holes as shown by Fixer above.

The bottom single vent is a gas /water drain but not sure if there is a vent hose attached or where it drains to (my foggy memory way back to my first six seems to recall it did indeed have a hose attached, might be wrong there, but seems likely).

The tee fitting large diameter side accepts a hose from the oil tank vent. no idea where the opposite side smaller connection goes to (on 911 applications the small diameter vent connection goes to the charcoal filter). I have an original six box where that smaller fitting is plugged, but have no way to know if that is correct. Can't think of any where that it might hook to on a six motor but who knows??

hope that helps

My goodness. Who would have thought so many permutations of the air cleaner box.

So there is not even consensus as to whether the bottom should have 2 large oval holes or 6 smaller round ones?

Can anyone share the length on the clips? @rgalla9146 Had a side-by-side photo in another thread, but hard to know which you have without knowing the dimensions.

If it was mentioned elsewhere, I missed it. The PDF parts catalogs show the following part number shared with 911:
Main body: 911-108-001-02 [914-6 and also 911 -68]
Also the gaskets, pipe, water drain valve, backfire grid shared. Not the carburetor connecting piece though.
