Sorry for the lacks of update. I'm quite busy nowadays so it is very hard for me to find time to write something. I still remember lot of 4G9X Naturally aspirated engine user especially MIVEC always complaining that performance parts for the engine is not that much if compare to VTEC and yes.. it is true.
What i admire about the 4G9X engine user is their spirit to build the engine to be as fast as VTEC so they keep on doing research and develop custom parts for their engine and i think it is very good for the motorsport scenes.
In my country, which is Malaysia, most of the 4G9X tuner here think that one of the performance part that is lack of variety in the market for the engine is intake manifold. So, they find ways on how to upgrade it with the parts which is readily available for the market. I think they are quite creative indeed :)
Below some of the picture of 4G9X series engine using aftermarket parts which originally made for Honda and Toyota :)

Creativity is the key point of this post. I think you can already guess what my next upgrade is *hint. See you in the next post :)
