Was in the Jalan 217 branch, the one next to Federal Highway. Their advise is ridiculous, just as long you use the correct rating/specs of iridium spark plugs then it could pretty much benefit the car in the long run.

P/S: Decided to change the spark plugs to the Denso Iridium Power, already changed it just now at my frequented workshop (before I changed car). Kept the original spark plugs that came with the car just in case, if really need to claim warranty then I'll just have a workshop to plug back the original spark plugs.

Haven't brought it to the highway for high speed testing but for a normal road drive, I feel that pickup feels steady, don't really know how to describe in words but the feel is much better. It claims to improve a little on acceleration but I did not feel it, anyway they claimed the acceleration to be improved by about 0.7 seconds but can't really be felt since I'm not driving like I'm in a drag race competition.

Also, I've read some feedback stating that overall, you won't be able to see much difference but a lot felt while cruising at higher speeds, it's easier to go even faster with iridium plugs.

Anyway, no harm putting something better since the price already justifies its estimated lifespan of about 100,000KM or so.

Now considering to replace the front light bulbs, considering those from Philips. Around 4000K is still fine right? Forgot where I read from but it stated that I need to consider the max/ideal range of temperature.

Anyway, would like to change to the white light but the H11 bulbs for the fog lamps are quite costly and was thinking to leave the fog lamps at stock. Then I can just replace the headlights with a brighter yellow light. Don't like the idea of the headlights being white and then yellow on the fog lamps.

Philips X-tremeVision:

The power2night offers about 50% more light while the X-tremeVision is about 100% more light (when compared with standard bulbs). Price wise, X-tremeVision is about RM90 more expensive than the power2night. Considering that I'll be driving in the city most of the time, I think the power2night is more than enough right?

Speaking of changing light bulbs, may I know how is Osram bulbs? Is it good? Which one you guys recommend? Osram or Philips?

Thanks!

show us the results, pal
As I also thinking of changing the stock one as it is not so bright.
Wira one is even brighter n yellowish lol

Guys for me i wont get this type of expensive bulb, 1 suggestion is our car light output is not as bright other car maybe you can install a electronic ballast something like HID unit but use back our standard bulb much brighter compare to stock but not as bright as HID unit. cost cheap some more.

Tried almost 50km on last bar. But make sure not jammed area la. Think the safe figure should be ard 35km.
Think H11 are vios 08 onwards. 05 vios use H3 & FL 06 use another code, cant rmb.

I never really left my petrol tank until last bar then only refill, not because I scare my car will stop in the middle of no where, but they said it's best to refill when it's 1/3 of the bar as the petrol is also act for coolant for meter or something, there's a discussion in LYN on this you can check on that.

cannot be la... when my last bar blinking and cont drive for about 20km, i can refill about rm 75 to rm 80 on ron 92 which is about 39 to 42 liters liao...

If for normal road usage 16mm is good enough .... feel more stable in medium to high speed corner not to forget it still have abit of body roll this is normal as our car chassis design to have some body flex. not to forget if during raining is still controllable if over-steer happen... 

if for 19mm the feel is much more stiffer compare to 16mm rear body flex is much reduce ....if over steer happen will be abit harder to control but not impossible if this happen. This is for ppl like take hard cornering or attack corner.

not to forget upgrade suspension as stock suspension are not design to attack corner.

Here there is a link guide from whiteline antiroll bar hardness chat.

tips: material that use for anti roll bar also important it is not just any steel bar it use a very special type of metal and there is few grade for this metal bar.... too technique...haha 

Anti roll bar

White Vios E coming soon.. where's the poison!! what to get.. what to opt..?

Anyone finds effective solution in substantially reducing the road and tyre noise of our vios? My vios E's noisy cabin is driving me crazy.

for quiet tires.. so far the best bet is CC5, because PLC no longer produced (not sure about this). XM1/2 too expensive for an entry-level tire.. PS3 is great, but noisy lar.. but still a lot better than NCT3/5.

IK 16,20 or 22 v should go for? I found out that those shops recommned different IK

that day when I changed to new battery, the technician told me that my engine timing is very low n engine kept shaking
once engine start, does this happen to u guys?

When should I change the timing chain thingy? TQ

1 more thing, the headlamp is not bright, does this happen to u too?
mine is J, got no fog lamp

Philips or PIAA is more yellowish? is it easy to install?

yes this is normal our vios engine is very loud, nothing much we can do only possible is use good full synthetic oil to reduce friction so noise also reduce but not much.
