SetVehicleMod is not working!

EDIT: Fixed, I had to use ToggleVehicleMod() to enable the vehicle mod.

Hi! I want to add turbo to my vehicle right after I have spawned it. But the script is not working, the vehicle does not get any modification, I have no idea why. What could the problem be? I’m using JavaScript.

Client:

function modifyVehicle(veh)
{
    SetVehicleModKit(veh, 0);
    SetVehicleMod(veh, 18, 0, true);
}
onNet("modifyVehicle", modifyVehicle);

Server:

RegisterCommand("veh", function (source, args)
{
    var customVehicleNames =
    {
        "skyline": "elegy",
        "skyline_gtr": "elegy2"
    }

    if (customVehicleNames[args[0]])
    {
        args[0] = customVehicleNames[args[0]];
    }

    var playerPed = GetPlayerPed(source);
    var heading = GetEntityHeading(playerPed);
    var [positionX, positionY, positionZ] = GetEntityCoords(playerPed);
    
    var veh = CreateVehicle(GetHashKey(args[0]), positionX, positionY, positionZ + 2, heading, true, false);

    SetPedIntoVehicle(playerPed, veh, -1);
    emitNet("modifyVehicle", source, veh);
});
