Air filters for 50mm Borla throttle bodies

George Cadavid · Oct 29, 2022

I have been looking and unable to find a source who sells 50mm air filters for Borla eight stacks. I believe K&N made them a few years ago. Any help appreciated.

I have K&N filters on my Borla Eight Stack. You might contact Dennis Olthoff at Olthoff Racing. If these or anything close are still available he'd know where to source them.

You have exactly what I am looking for. I called Olthoff and Roush and neither have them. It appears K&N was the manufacturer but don’t make them any longer. Dave if possible can you take a picture of the inside of one of the air filters and post it? Thank you

I had the same problem, you are forced to buy the K&N through Borla at a premium.
So contact Borla.

Hello George, I tried to obtain those very same style filters for my Borla Eight Stack System and failed so ended up designing and making my own. Not sure if this helps you but I have attached some photos of what I made. Ignore the name on them, I added this as what I thought was a fictitious name just to add more detail to them.

I just spoke to Patrick from Borla who said they are waiting on several back order air filters from K&N. Seems they source them from Roush. They have been on back order for about 4 months and expect delivery by Christmas. I placed my order but like Bill said they are not cheap. I paid $356.00. Robbie your setup looks awesome and your creativity makes it one of a kind. Thanks everyone.
