The 40,000 km stop on my Swift: air filter, plugs and fuel filter all at once

My ZXi Plus is nowhere near this yet, but I like knowing what's coming so the bill never surprises me.

I was reading through the Swift schedule on MyCarHelpline and the 40,000 km or 48 month stop is the one where three things land together: air filter, spark plugs and fuel filter. Before that the filter only gets cleaned at every 10,000 km visit, which is why the earlier services feel so light on the wallet.

V3Cars puts that one at roughly 6,250 rupees at an authorised workshop, labour included. Not scary for four years of driving, but it is the stop I would plan around rather than walk into blind.

If you have crossed 40k in your Swift, I would love to hear what your actual invoice looked like and whether the plugs made any difference to your tankful average.
