EGR / PAIR Emissions Block Off Plate for Scooters & Mopeds (Standard)

EGR/PAIR Emissions Block-Off Plate for 50cc and 125cc-150cc Engines

This block-off plate is made for 50cc 139QMB and 125cc-150cc GY6 4-stroke engines. It seals the emissions port in the cylinder head, which is useful when the emissions system is faulty or when fitting an aftermarket exhaust. It is one of the more straightforward modifications you can carry out at home to help engine performance.

Function and Advantages

By closing off the emissions port, the plate helps stop leaks within the emissions system that could otherwise reduce engine efficiency. Sealing these ports can help your scooter or moped perform better. Many people fit it alongside a new exhaust system, as it contributes to a cleaner overall setup.

Fitting Notes

To fit this plate, you may need to adjust the carburetor's vacuum hoses or switch to a single vacuum intake layout. Depending on your model, a non-emissions head cover may also be required. This part is meant for off-road use only and should not be used on public roads.
