RVNG O2 Spacers solve the post-cat check engine light that shows up after a downpipe or cat delete. The spacer moves the rear oxygen sensor slightly out of the direct exhaust stream so the readings stay within range and the CEL stays off. Every spacer is checked for defects before it ships.They work 100% of the time on twin-turbo vehicles and roughly 85% of the time on single-turbo cars — on some single-turbo setups a CEL can still appear depending on the tune and configuration.Effectiveness Twin-turbo vehicles — effective in essentially all cases Single-turbo vehicles — effective in roughly 85% of cases Emissions disclaimer: This product is not legal for sale or use on pollution-controlled vehicles operated on public roads and is intended for off-road, race, or closed-course competition use only.
