Just give any service centre a call to ask for the price. Then you compare against outside spare parts shop, just choose whichever cheaper lor...the spark plug also can ask spare parts shop for advise. Some manufacturers put in the spark plug type in their car manual, you can have a look there first.
Flutter?? You mean like the when the ceiling tube lights are starting? If so, not good sign. When the AFS is working, you can see the light beams shift towards the direction of the turning of your steering wheel.
Speaking of the headlights, any of the forumers actually witness the auto high beam control actually working? Even when i set to auto for both headlight and highbeam, never seemed to see it activated in real life driving before. I check manual to confirm whether got fault but my indicator light showed it is in ok condition.
well not exactly flutter like fluorescent lamps lighting up per se (if i understood you correctly).
more like the light beam "jiggles" when going over uneven roads, like something is loose in the headlamp housing. its very very minor, just something i noticed and wanted to check with other owners

my HBC works fine. you have to be on a really really dark road for it to work. mine wouldn't come on if there are street lamps bright enough for the camera to detect. did you set your headlight stalk to the high beam position, i.e pushed forward (away from you)? maybe try disabling and re-enabling the HBC in the car settings and see if it works.
