Here is what many H22 owners have been waiting for. The Accord Euro-R intake manifold. We've had these manifolds for some time, supplying our local enthusiasts and have decided to offer them to our out-of-state customers. This is a special intake manifold, because unlike the dual-butterfly configuration found on the H22, this manifolds configuration is like that of the Integra Type-R....single butterfly with shorter intake runners. This intake manifold will work on any H-series or F-series cylinder head. This intake manifold is specifically designed to fit on the Accord Euro-R, so when purchasing, please be awaire that modification is needed to ensure proper installation and operation. However, when this piece is installed correctly, the engine gains about 6-8 horsepower throughout the powerband over the factory unit. Horsepower gains will vary depending on your engines setup configuration.
