thanks
many people says put IR spak plug give good power but actually it is not. dunno have to blame people mindset or its advertisement

Iridium sepakberak is very efficient geh. Firing is focus, therefore it can easily achieve complete burning compare to big legged sepakberak

If you remember the older days when cars still have birds and butterfly in the engine head, those valve need a valve seat to align them in place, when valve accumulated too much tahi can't close tight, as a result white got white smoke when pickup from trafik lite(not talking about vapor during rainy days). This is bcoz engine oil leaked into combustian chamber during idling as the valve tend to be working the most lazy time.
Here's the PROVEN - MYTH. My bro's 4G15p got white smoke on traffic light pickup. After changed to iridium berak few months, the car no longer emit white smoke on traffic light pickup. Flickering vacuum reading became stable like new car! I do not believe him, so I got myself another set of iridium on my
3K engine. To my surprise, few months later I did notice my vacuum settled down, become less active on idling. My
Levin is known to be fuel gazzler, but I found my FC gradually improved. I can't remember the exact figure bcoz back then dun hab fuelly, as far as I can remember was from average 10km/litre increased to 12km/litre(with racing carburetor). My next experience was Iswaga 4G13p, currently with unker Choy. I whacked the car until piston ring loose, too much engine oil being spill into combustion chamber, result the car jerky/lack of power/drink fuel like pour water into longkang. After iridium berak plonk in 2005, MORE WHITE SMOKE EMIT, but the restored some power, reduced FC. I had the DBKL ubat nyamuk car running around for another year until I have sufficient fund to overhaul it. My last experience was my Wigra 1.6XLi. This car got no problem, engine is tip top, only 120kkm even it's 16 years old. But hor, when slow down time engine die. When reach traffic light, engine die. When traffic jam infront I brake, engine die. I saw lenglui pass by, slow down blow whistle, engine oso die. I overhauled the whole intake system, I change plotong sepakberak, the car's fine for few months, same problem again. Change sepakberak again, again it only lasted few months. The ranjiao Singgalingam friend say could be my berak wayar rosak, go an pull my berak wayar then snap 9 jor. Originally no rosak now become rosak had to change berak wayar. Even after change berakwayar, car still jerk and die engine when slowing down. Suddenly I felt like kena lightning strike, reminds me of the good old iridium berak, immediately get a set of them plonk it in. The Wigra no more jerk, no more engine die, FC improve from 1 full tank maximum 350km to 400km(sometimes 450). Until the day I sold car, my FC still improving.
Performance? I don't think it's significant enough unless your injector was tuned inline with the sepakberak upgrade. The last time I got my sepakberak was RM120/set of 4. Not sure whether its cheap/expansib, but out of desperate so I did it.

Don't expect it will boost up your car, but see the effect over the long run. This is a mod that is quite affordable but 2nd most hard work in your engine(champion goes to ignition coil, and it's not cheap to mod ignition coil).

davidke20, coolkwc & mengsuan,
Regarding the fast blinking of signal after changing to LED bulb, do you guys think those canbus error free LEDs will resolve this problem?
