Unless you are going HIGH boost 20psi+ Plastic IM's are the best for these basic reasons over aluminum.
1)It saves alot of weight over aluminum2)Quieter than alumunum3)Conducts heat alot better than aluminum4)Stop needless vibration between the manifold and the throttle body.5)Better flow than Aluminum
The plastic Nissan, Toyota, Honda, etc. are using in motors now is composed of VERY durable plastic.
This is the reason why there are no spacers, aftermarket IM's or anything other mods related to the IM's available for us or the new G3x/3x0z VQ___HR's
