Yes, any modifications that affect the vehicle's appearance or performance must be registered. Below is the vehicle modification registration process: 1. Submit an application: Before modifying the vehicle, the owner must fill out the Motor Vehicle Modification Registration Form and submit it to the local vehicle management office along with copies of the owner's and agent's identification, the vehicle registration certificate, the vehicle license, and other required documents. 2. Process at the vehicle management office: Within three days of acceptance, the office will inspect and archive the vehicle's records, confirm the vehicle's identity, and issue new license plates, a vehicle license, and an inspection compliance mark. Modifications can only proceed after approval. 3. Update the vehicle license: After modification, the owner must return to the vehicle management office to re-register the changes. If the modifications alter the vehicle's appearance, new photos must be taken, and a new vehicle license must be printed.

Last time I went to the DMV about modifying my hood. If you want to register a vented hood, it depends on the extent of modification. If you completely replace the original hood or the vents alter the position of the chassis number, then you definitely need to register it. The process is quite troublesome - you'll need to bring the vehicle registration certificate, ID card, and official certification from the modification shop to the DMV. But honestly, the DMV is being extremely strict about such modifications nowadays. Many people who add cooling vents get ordered to restore their cars to original condition. My advice is don't rush into modifications - first go ask about specific requirements at your local DMV window, as enforcement standards really vary by region. Also remember to get proper invoices and modification lists from the shop, otherwise you'll definitely fail annual inspection and might get pulled over frequently by traffic police. The key points are not altering the main body structure and ensuring safety standards are met.

We who are into car modifications know the ropes best. A vented hood counts as an exterior modification, but the drilling location is crucial. Drilling in the middle of the hood is no big deal, but if it's too close to the windshield and affects visibility, you'll definitely be ordered to restore it. The success rate for getting it registered isn't high, so be mentally prepared. It's advisable to find a reliable modification shop—they have channels for certified aftermarket parts. After the modification, make sure to keep all receipts; otherwise, you won't pass the annual inspection, and the police will deduct points if they catch you. Honestly, for summer heat dissipation, installing a wind deflector is more practical than a vented hood. Going for a vented hood for looks comes with its costs. Also, after the modification, it's best to do a light reflection test immediately to avoid the hood's glare blinding you.

Don't get your hopes up too much about modifying the hood and getting it approved. The DMV's judgment standards are actually quite vague, mainly focusing on whether the modification affects safety. The openings must not compromise the structural strength of the frame, have sharp edges, or affect pedestrian collision safety. From personal experience, if the holes are too large, you might even be required to install dust screens. My cousin's modification was deemed illegal last time—aside from a 2,000-yuan fine, he had to dismantle and restore it. It's advisable to take photos and consult the DMV before making any changes, or opt for detachable versions. After modification, promptly smooth out any rough edges to avoid scratches, and regularly clean leaves and debris—it's quite a hassle.
