Which Air Filter for 1984 Goldwing Interstate

Postby Lynnmarn » Tue Nov 19, 2013 12:14 pm



I ordered an Emgo air filter from Amazon. The part number is 12-90021 which is what it is supposed to be but it won't fit on my 84 Interstate. It has two holes in the top instead of one and the top, center is recessed one 1/8 inch less than my original. The height, width etc is exactly the same. As a result the top cover won't fit snug around the edges. I have included a picture for inspection.

Should Emgo filter have two holes and should it fit. Do you think I got the right box but not the right filter? Is there a good filter other than K&N and the OEM one which will fit my bike. If Nampa makes one what is the part number.

The filter with 2 holes should fit. The 2nd hold is for the LTD and SEi version. There's an air sensor that fits into the air box top and then is supposed to fit into the hole in the filter. It's supposed to have a rubber grommet with a center hole for the sensor to fit into.

Put some duct tape over the hole….done deal.

The big problem is that the filter case lid doesn't fit down tight because the recessed inner part is not deep enough. Doesn't that make a difference.

The filter should have come with some rubber plugs that you can stick in those holes if you don't have use for them.

I remember having the same issue with an Emgo filter on my 1100. I just fastened it down as tight as it would go, and next time bought an OEM Honda filter.

It won't hurt anything to have the cover not down all the way, as any air sucked in there will still be filtered before it gets to the carburetors, as the filter is sealed to the carb intake by the pressure of the lid/wing nut.

Thanks for your help. I just ordered an OEM filter of eBay and I am going to return the Emgo. It kind of bothers me that it doesn't fit. So the perfectionist in me says do it right.

When I got my filter in the spring it looked the same as yours. I ended up taking a plate out of the bottom of the filter box and the cover then fit tight. Look in the bottom of the airbox to see if there is a rubber plate that can be removed. If not there is not problem with the lid being up just a little. Like was said the air has to pass though the filter. It might also be an emprovement with some extra air flow.
