CEL Delete Kit / O2 Sensor Spacer (Universal)

Installing a catless downpipe will trigger a check engine light (CEL) once the ECU detects the missing catalyst. This kit resolves that without a tune, using O2 sensor spacers calibrated to sit within normal catalyst parameters.

Complete Kit Includes:

• Calibrated O2 sensor spacer(s) sized for post-catalyst sensor bungs
• Universal fitment across most makes
• Lifetime warranty

Installation: Simple bolt-on install into the post-catalyst O2 sensor bung. Note: vehicles from 2019 onward are more sensitive and the CEL may not be fully eliminated in all cases — the kit may still delay activation. Contact us if you hit a fault code after install.

Fitment:

• Universal — compatible with most catless downpipe installs
