Good evening Tuners,

I would like to find out based on the experiences and opinions of you seasoned RB guys, if there is an aftermarket air intake manifold which gives better performance than the stock intake manifold. My reason is because I recently installed an rb20det engine and manual trans. in my A31 Cefiro, which was not originally turbo charged so it doesn't have the two port holes in the apron for the original SMIC piping, and i wanted to know how is the best way to run the IC piping for a FMIC, while maintaining optimum efficiency...or should i just install an aftermarket intake manifold, where the piping run would be much shorter and in effect, have better performance?

Your Advice would be greatly appreciated.

Thanks!
