i'm not laughing... i'm in the process of finding an alternative to the huge double tapered horned monstrosity on my '67 mark ii. it, and its cohort, that oval-holed aluminum conduit to the carbs pictured on the right of the pic shown above. it frustrates attempts to access the choke carb. i've purchased a couple of filters, one for each carb, from moss and despite having obtained verbal assurance that they fit, confidence is lacking....

It's either that or the pancake one.
The one in Glyn's post is better as it pulls cold air from outside and doesn't draw it in from the hot engine bay.
I recently changed my MK2 from the "pancake" filter system to the "drum" system in Glyn's illustration.
It gives better access to the carbies and cooler intake air.

A bit cooler, but not cold, as you are still pulling air from behind the radiator. I had an air temperature sensor on the filter housing on my S Type and I found temperatures were fairly consistent at 30-35°C above ambient at highway cruise speeds, and in stop and go traffic it was common to see air temps at 90°C. I changed the filter arrangement to one that truly takes air from in front of the radiator and the air temperatures dropped to 5° above ambient.
It's very easy to sort the convoluted pipe to draw cold air as long as you have a proper radiator fan shroud. Where Bill & I live quality of filtration is far more important than IAT. Of course it's nice to sort both. Small pancake filters don't cut it. It only takes a heaped teaspoon of dirt over time to ruin an engine. Watch the Cummins film "The Hourglass" ~ it's old but as valid today as it was then.

Or make a hole in the fender well. I guess it was designed to keep the carbs from freezing up in the winter.
The English never imagined people driving the Jags in 35 to 40 degree weather I guess.
I did end up putting a hole in the inner fender and used an XJ40 style air filter assembly mounted in front of the front tire. Then ran straight piping across the engine. I don't have any photos, or I'd share them.
