One of the best mods you can do to improve the comfort in your mkiv Supra!
 
Our Supra's did not come with cabin filters from factory, but luckily the recess has been provided to make this a super easy mod to do!
 
This kit consist of:
- 4x Activated carbon air filters (you need 2, so includes a spare set)
- Nylon cover that holds the filters in place
- hardware to mount the cover in place.
 
The only DIY part you need to do is cut the opening into the plastic, which has been explained beautifully in this forum thread.

Big shout-out to the guys pioneering this in this thread!
 
Filters are also seperately available for maintenance.
