An improved device for supplying additional combustion air into exhaust ports of a multi-cylinder internal combustion engine. The device comprises a horizontally disposed air distribution pipe communicating with a source of air supply and having a flat bottom wall or walls supported on flat upper surfaces formed on a cylinder head or exhaust manifold portion. The pipe is formed with a plurality of apertures through its flat bottom walls. Each of these apertures is aligned with one of a plurality of air distribution bores formed in the cylinder head or exhaust manifold portion and each communicating with one of the exhaust ports. The pipe is directly secured to the cylinder head or exhaust manifold portion by metal bands without the aid of any branch or connecting pipes.
