At JUN, In order to develop the 4G63 engine parts, JUN HYPER LEMON EVO 5 was used as the test vehicle, and hard running in each circuit was performed. The durability test running has repeated and has been performed. Processing for demonstrating a part performance and an engine performance to the maximum extent is performed into the engine. We feed back such technology to a user and high quality engine processing is offered by JUN.

We receive a customer's cylinder head and perform high quality processing to a cylinder head. It is also possible to build a JUN parts into the cylinder head which processed as a short head assembly. Moreover, we can make cylinder head in the specification for which you wish. We prepared two menus, menu1 and menu2. Please ask by the E-mail for details.
