MODSTOCK EXHAUST MODIFICATIONS
O2 / Lambda Sensor Spacers Available
Got an engine management light after fitting a sports cat, decat pipe or aftermarket exhaust? Modstock has the solution.
Our O2 / Lambda sensor spacers are designed to move the secondary oxygen sensor slightly out of the exhaust gas flow. This helps reduce false catalyst efficiency readings that commonly trigger the check engine light after exhaust modifications.
What are they used for?
• Reducing catalyst efficiency fault codes
• Helping prevent EML / CEL warnings after decat or sports cat installs
• Supporting smoother running on modified exhaust setups
• Ideal for performance and custom exhaust builds
Precision machined and easy to install, these spacers are a popular option for enthusiasts looking to keep their modified setup running cleanly and reliably.
Suitable for many vehicles using standard lambda / O2 sensor threads. Straight, angled and mini-cat styles available depending on your setup.
Why choose Modstock?
