Parts and fitment guide for your 1978 CB400A

For the CB400A, identify the oil-filter housing and airbox fitted before choosing replacement filters. An engine or airbox swap can change the filter application.

Browse by repair

Selected parts for the 1978 CB400A

Check the product application, dimensions and pack quantity before ordering.

  • Oil filter — 1978-86 Honda CB450 / CB400 Oil Filter ~ Replaces 15412-413-005
  • Stock air filter — 1978-82 Honda CB450 / CB400 Stock Type Air Filter ~ Replaces 17211-413-000
  • Spark plug cap — Honda CB Spark Plug Cap ~ XD05F

Identify your 1978 Honda CB400A

Check the frame identification, engine markings and registration details together. A photograph or paint colour alone cannot establish model year. An engine swap or previous repair can change the parts your bike needs.

Honda CB model guide

Match the CB400 application

The oil-filter element replaces 15412-413-005, 154A1-413-005 and 154A1-MA6-000. The air filter replaces 17211-413-000. For a changed airbox or ignition system, compare the fitted filter housing and plug-cap connection rather than relying on the motorcycle name alone.

Fitment questions

Do parts from another CB400 model fit my 1978 CB400A? Only when the product listing explicitly includes both applications. CB400F, CB400A, Hawk I and Hawk II names do not establish interchange. Check the installed engine, carburetors, brakes and controls against the listing.

Does an OEM reference mean the part is genuine Honda? Not by itself. Aftermarket parts can quote the Honda number they replace. Look for an explicit genuine Honda description if brand origin matters; “OEM-type” or “replaces OEM” does not identify the manufacturer.
