<2.4L ENGINE>

The intake manifold is designed to improve the low, 
middle and high torque by optimizing the port diame-
ter and length. A port opening with an optimized bell 
mouth shape and improved the inside roughness of 
the port reduces airfloe resistance.

<2.4L ENGINE>

The exhaust manifold is design to reduce the heat 
capacity and to improve exhaust gas performance by 
preventing exhaust interference through dual pip-
ing.The improvement of the exhaust gas perfor-
mance just after engine start is designed through the 
quicker warm-up in the catalyst by installing manifold 
catalytic converter (MCC) on the dual portion.

The flange plate thickness is reduced for lighter 
weight.
