Air box adapters / rubbers / rubber boots, what ever you like to call them, for your Honda CB500 or CB550! You know these boots. Once they’ve been sitting for decades they harden up and shrink. They become impossible to put back on.  You may have tried boiling the old ones or heating them up some how, and it still doesn't work. Maybe you can get one or two of them on the carbs but they won't all go on. Save yourself the trouble with a new set! Made from quality rubber that holds up well to gasoline and ethanol.

We also have the clamps for these boots available here.

    These are not the same size as stock! They sort of fit but will require tuning

    Great so far!

    My engine was being choked out due to an air leak. I was able to buy this set and use on of the connectors to replace the original. It was an easy fit and installation. Quick tip: be sure to get the clamps from 4into1 because the original metal clamps are too wide for these connectors.

    not a perfect fit

    Posted by nmcbnyc on 5th Jun 2018

    One of the boots was really hard to get on and keep on at the right position. However it might just be my bike since the original boot did the same thing. Sizewise , they are identical tho the OEM but the rubber quality seems cheaper.

    Great fit but after a year they are all cracked.

    Posted by David Pardoe on 5th Mar 2018

    I had to take off my carbs after about a year of having these repro boots on my bike and to my surprise all 4 have a ton of cracks. I need to buy new ones but stuck with these same ones. I hope Honda makes them.
