Cel Delete Kit

The installation of catless downpipes will result in an inevitable check engine light (CEL) as the DME will detect that emissions are not being burnt up by the OEM catalyst. To remove this CEL without having to tune it out we offer the CEL Delete Kit which is comprised of O2 sensor spacers specifically calibrated to comply with BMW's parameters for a functioning catalyst. These install into the post-catalyst O2 sensor bungs, effectively removing the CEL that would otherwise appear.

Vehicles manufactured from 2019 onward are highly sensitive, and the Check Engine Light (CEL) may not always be eliminated. However, the modification may help delay its activation.
