The Panda is on 12k intervals, with the plugs getting changed at 24k (or every 2 years). The 500 is on 18k intervals, so going on the "replace every two years" requirement, the plugs wouldn't get changed until 36,000 miles which may affect the engine running (and more importantly these days- the emissions).

If there are trailing numbers after the part number, then the gap should be specifically set as per the manufacturer's part code designation (e.g. Brisk RR15IRY-7, gap size is 0.7 mm, Brisk GOR15YTE-3, gap size is 1.3mm NGK BKR6E-11, gap size is 1.1mm, Denso T16EPR-U15, gap size is 1.5mm, Champion RC10YC4, gap size is 1.0mm).
