In this video I install a intake came sourced from a BP5A mazdaspeed miata engine into my NB1 Miata. Things don't go quite as planned as I had to remove more parts than expected but it worked because I found a leak!

Thanks to @Bbeavis for all the great 3d models, he has some really helpful tools including a cam gear locking tool, seal installers and more!
