These are a very well made snorkel, made from high quality, strong plastic.  I've found that once these are mounted, these are very firmly attached - the mounts are great.

Complete your Jimny with a great quality, well-made snorkel. 

Comes with a template sheet to help with fitting and all the parts required. You'll need a drill and a hole saw, as well as basic tools to fit.

Bob shares some great tips for fitting a very similar snorkel in this video (but this kit DOES come with a good template)...
