Frequently Asked Questions
How do I check if regulator parts fit my car?
Use your vehicle details (make, model, engine) to confirm fitment before ordering regulator parts. Matching the exact engine variant helps you choose the correct part first time.
OEM vs aftermarket regulator: 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 regulator?
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.
