Visually inspect the breathalyser for obvious damage, wear marks or fluid leaks
Check the OE/OEM part number on the old component for an exact cross-reference
Use your vehicle registration or make/model/engine to verify fitment

Frequently Asked Questions
How do I check if breathalyser parts fit my car?
Use your vehicle details (make, model, engine) to confirm fitment before ordering breathalyser parts. Matching the exact engine variant helps you choose the correct part first time.
OEM vs aftermarket breathalyser: what's the difference?
OEM parts match the original equipment specification. Aftermarket parts from quality brands are compatible alternatives that often meet or exceed OE standards at a lower price.
How can I find the OE number for breathalyser?
Check the part on your vehicle, your service history, or manufacturer documentation for OE/OEM reference numbers. Cross-referencing OE numbers is the fastest way to find compatible parts.
