This oil cap has been out of production for years. At Tokyo Auto Salon 2016 a representative at the Top Secret booth informed us that these were recently put back into a limited production. We snagged up only four of these fantastic looking oil caps for a few of our customers. This is the last one! Grab it while you can!
This is threaded for Nissan / Infiniti and Honda engines. We do not know of any other specific fitment.
