Seems that parts for the 2016 outlander is very limited. And i have read the thread about struts and intake is outdated.

Want to know if those parts would be interchangeable with the 2016 os?

From pictures theres a bit of a difference. In the engine bay of a 2016 there is no box like compartment of where the filter goes.

 

Yes all aftermarket 11+ OS strut bars will fit. 16 is the same the product just doesn't say 16 on it. As far as intakes all the 08+ lancer/OS intakes fit, same engine etc. only thing is Mitsu changed the maf to oval style in 14/15 so if want to fit aftermarket would have to modify to fit since all of them are the old square style. There are currently only 2 aftermarket intake options for the oval maf, road race and aem.

 

As far as a "drop" in filter Mitsu also changed the filter to a diaper style from the square style, which there were plenty aftermarket "filter" options. The diaper style has a few drop in filter options l

 

Rob at RRM has some intakes for the Newer Mitsu MAF's. I told him about the machine work I did on mine, he went out and got a new sensor and had a run of intakes made for the new style, so you should be good to go if you order theirs.
You can go cheaper and get a hindged FSTB, but I prefer a solid bar my self.
