Best Air Filter for Super Bug?
navis - May 11th, 2012 at 06:30 PM
Hi All
Having issues with performance on 72 Super Bug which has a small chrome pancake style air filter.
Mechanic recommended replacing with stock air filter for better compression and performance.
Anyone else agree with this or have input on best air filter for stock carb on super bug?
Thanks

Those chrome pancake filters are absolutely hopeless, strictly a visual thing.
THe oil bath ones do the best job but are a bit more restrictive than the later bug paper element ones.

The oil bath filter on mine seems to work pretty well.

Stock paper element ones.
They were on 73 and later bugs

Will they fit an earlier bug joel?

The stock paper element and housing works the best on my 74 1600 tp.
I have read that the carby requires a minimum distance above the airhorn to the top of the airfilter for correct atomisation of fuel. (35 mm?,
More?)
The small aftermarket has half that.

Yep, all bug single carbs have the same 50mm air cleaner spigot.
The whole velocity tube thing is a bit blown out of proportion.
It does help to a degree but your not going to notice if its not there.
THe oil bath filters have one but its purely to stop the oil from splashing down the carb throat.
The stock paper element filters like I posted above have nothing and there is no noticable difference in peformance.
THe pancake filters are crap mainly because there is just not enough filter surface area with them, they don't seal well and have no provision for
pre heat.

Hi Joel,
how can a paper air element be less restricting than an oil bath air filters??
the air just hits the oil and bounces UP & down into the carby..
I've never liked paper air filters always prefer the K&N type reuseable filters..

They would have been fine when new but after 40+ years of sludgy oil dust and dirt build up in the mesh I've seen a few badly caked up ones.
Cars that have spent their life in the country would be worse than city cars,
Alot of dirt roads around here still and many Kombi owners seemed to think it was a great idea to prop open the engine hatch so the motor just sucked
in all the dust and crap of the back wheels
I've had to throw a few oil baths out they were just so badly blocked up they couldn't be cleaned out.
THe Panel filters that 73 and later bugs have are still what cars use now,
Just blow the element out every service and replace every few years all is fine and dandy.

Nice one everyone thanks for the input, appreciate it. Have tried a crappy old oil bath filter and it made a HUGE difference to the running.
Craig do you have the later paper filter assemblies? Let me know if you do.
Now just got to sort out the rough running and backfiring when cold.....

said the oil bath ones are stock... is that a better option?)

i dont mind the maintenance...i just want a cool running bug

the main reason they went away form the oil bath is the paper one was cheaper to make and install.
hell if they can hold something in with 3 screws rather than 4 they will because it saves money.
ether air filter wont really affect the temp that the engine runs at. so it comes down to personal preference

Hi guys
Yes, they would have saved a bit of money changing over to a plastic filter.. it would have cost a bit to keep making the oil bath filter.. I don't
drive on dusty roads if I can, as I think about the dust all the time. I bought the oil bath filter I am now using but it had inside it a paper
filter that fitted into the oil bath bottom.. now that was probably rare and expensive to have these days.. I thought it was the original oil bath
top..lol.. never ever seen one before and probably never will... lol
it was un usable.. maybe fitted with oil still in there??
I made up an extension piece for the chromed cheap air filter
from PVC and it fitted on great... was about 75-80mm long..
but went back to the oil bath.. and preheater pipe.. etc..
cheers
