Find the right SMART-O® plug.
Choose your market, then your vehicle. The finder returns the correct SMART-O® plug, the matching washer pack and current pricing before you order.
Cannot find your vehicle, or running a modified setup? Send the details and SMART-O® will confirm the right plug before you order.
Email a fitment check →Have the old plug? Use the SMART-O® Gauge.
The physical gauge is the fastest way to confirm thread diameter and pitch when the vehicle database is unclear, modified or incomplete.

- Remove and clean the existing oil drain plug.
- Slot the plug into the SMART-O® Gauge.
- Match diameter, pitch and head marking.
- Order the corresponding SMART-O® plug and washer pack.

Already know your thread size?
Skip the vehicle lookup and order by thread size, head marking or replenishment pack. This route is built for service bays that already know the common sizes they use every week. Motorbike fitments can be matched the same way — by thread size or with the SMART-O® Gauge.
