Set of 4 reproduction rubber intake insulators, manifolds or carburetor holders, call em what you like. For use with the stock carburetors on Honda CB350F and CB400F. If you've discovered cracks on your stock intake boots, it's time to replace them because they're most likely leaking air which leans out your air/fuel mixture.
Comes with the o-rings to seal the manifolds to the cylinder block. Does not come with hose clamps.
Inner Diameter: Attaches to the Carb: 27mm Attaches to the engine: 24mm
Outer Diameter: 42mm
Overall Length: 31.5mm
Distance between mounting holes: 50.5mm (2") Measured from the center of each hole.
Replaces Honda Part Numbers: 16212-333-030, 16213-333-030

CB400F intake set
Good replacement, fits perfect. Do not put your rebuilt carbs back on without replacing these.
-
Intake insulator
As good as the factory original
-
Ruled out these as the source of vaccum leak
These replaced the old hardened intake insulators on my 73' cb350f. The new orings give me piece of mind knowing there won't be any vaccum leaks there.

Carburetor/ intake insulator set
Perfect fit, timely delivery.

Right size.
Replaced the old ones that were stiff.

Perfect idle now
I could never get my wife's CB350F to idle evenly. I replaced the old age/heat hardened rubber insulators with these and the bike idles perfectly now. The carbs were also way easier to install with the new insulators. Thanks to the other reviewer, I picked up a bag of stainless steel, button head allen bolts ahead of time which made the install a snap and look very clean. I went ahead and ordered a second set of insulators for my 400 four. Great product, great fit, highly recommend!

Excellent!
These were a much needed replacement part for the fossilized insulators on my '72 CB350F. Very nice product and perfect fit.

1976 cb400f
These intake boots fit perfect. The only thing I would recommend would be some Allen bolts to go with them to replace the crapy Phillips head bolts on the bike.
