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