Yes they are cheap online but shipping is like 120 and you have to add 75 core charge. I paid 287 for mine brand new. But remember the zl1 diffusers don’t come with the heat shields, those have the be bought seperate and each one is worth like 120.

Also the part number for the quad tip diffuser is 22829478.
Price is negotiable. Just looking to get rid of the diffuser.
