We understand your concern. Yes, you'll need to have your vehicle smog inspected. The DMV will not renew your Hyundai's registration without a valid smog certificate on record. You may be able to bypass a smog check at a regular smog inspection station due to have received an engine replacement, however in order to do so you'll need to contact the state's smog check referee office and request an exemption. However, they too will want to smog test your vehicle in order to ensure the engine replacement was conducted properly. So either way, a smog check will be required. We'd recommend
finding a smog station in Alhamba that can get your smog test done accurately and quickly without the appointment required to visit a referee smog center.
