914-6 Air Cleaner, Different than a 911? Options

[GeorgeRud]

I was recently asked whether the 914-6 had a different air cleaner housing from the 911 of similar vintage. I had always heard that it was unique in being flatter on top to clear the engine lid. Upon checking the PET, I saw it does have a 911. part number, so I now wonder if I was mistaken. Any gurus out here know for sure?

I'd defer to GMS as the expert on this, but to the best of my knowledge the 914-6 had plastic air filter housings, which as stated here is flatter across the top. Later MFI 911's also had a plastic air filter housing, but I don't know for certain if this is the same part as the 914-6, not sure on the dates used though.

914-6's and MFI cars did have what I call the "fire starter cold start system", which involved spraying gas down the intakes via a tubes in the air filter housing. These were disabled through a recall. Risk aside this set up is helpful starting a MFI car in cold weather.

The metal air filter housings can be made to fit, but most I've seen require some clearancing to fit, as they rub the engine lid.

I'd be willing to bet if you inspected the engine lid, or the air filter housing something has been modified a little.
