Lambda sensor spacers/foolers?

[MikeyM]

My Zed like many is debated and engine light is on..so wondering if anyone has bought and tried these spacers / foolers that are available.. did they work and what thread size is required ?

 

I know once anything is fitted the ecu will need a reset as well

They work fine, speak to Chris at tarmac sports he does them I bought mine from him!

I tried everything on mine, eventually I bit the bullet and got the rear sensors mapped out.
