Exhaust Lambda Sensor Spacer Fooler 135i 235i 335i 435i M2 M235i | MTC Motorsport
MTC Motorsport Lambda Fooler Spacer for use with any Sports Cat or Catless Downpipe
The spacer is designed to move the lambda sensor after the catalytic converter away from the flow of exhaust gases when a car has a sports cat or decat to keep the engine light off.
It can also be used in some applications to move the lambda sensor away if it’s touching something.
The measurements are:
- Height when fitted: 45mm
- Total height without fitting: 50mm
- Length: 45mm
- M18 x 1.5mm thread
On test vehicles we find that it works very well on most cars with a decat fitted.
These spacers are made only in T-304 high-grade stainless. We don’t supply the cheaper steel spacers as they are known for rusting and being difficult to remove after a few years.
We have found lots of other spacers don’t work as the hole is too big letting the gases flow through however we have managed to get these perfect.
This can be fitted at any angle depending on where it sits better when installed.
Please contact us if you have any questions about fitting to different vehicles.
