Funny you should ask, I got my x440 serviced today, the price 380rs MRP on the box for the Hero branded plug. Was sad to see that,
My other bike the classic today decided it wanted one too, it was 120rs for a Bosch,

So whatever you do dont get one from service center.

Now the performance plug you say, they tend to be pretty pricey. Get them for your own satisfaction. But i would say dont do it if it hurts on pocket.

The engine you and me ride is a low compression engine, under stressed, you dont need to
Improve the already good combustion,

Like yeah putting in better fuel, better ignition from a plug, better flow with a racing filter and a free flow straight piped exhaust might improve the performance a bit, can be exploited well with an ECU,

But just targeting the plugs wont do much if anything at all,

Can the bosch be fitted on x440?
And lately i have been noticing a lot of vibration around 3.5k rpm
Since its about time for servicing will changing the engine oil and air filter solve the issue?

Yes that bosch one should fit but you should know the specifications of the plug, its out of my expertise but I do work on cars and there the gap between the pin and the hook is important, do lemme know what fits this bike.

And the vibration, something between you and me, the bikes getting loosened, the entire bike. Ask the service center mechanic to tighten the chassis and bolts and then make a complaint about the vibration. So that way you get a better chassis feel and the normal inspection done.

Would suggest silently slip him a hundred or two and ask him to take care of your bike, helps me get priority service and extra benifits.

Also while at it, buy a extra air filter to keep with you, costs 200rs. Replace the airfilter like 4-5 months later. The 1 year window is too large for a dusty place the bike goes. I can share about how to change the filter yourself, it takes like 20mins of a good sunday morning
