Ya, installation around sri kembangan(equine)? Confirmed buyer also.

For selling such a good product as a very reasonable price, I think the least I can do is to write a review here.

Items: IceCube's Power Booster (DIY) + IceCube's Grounding cable (DIY)
Target: Wife's Kelisa 1.0 Manual 2002 or 2003 (forgot).

Installation:
Fast and easy. Everything provided in the package.
For my case I only need:
1. A wrench.
2. Some tissues (to wipe the battery area and attach the PowerBooster with dbl-sided tape. Dbl-sided tape already included.)
And some optional tools:
1. Torchlight.
2. Pliers.

Result (Performance):
Instantly feel better power and quieter engine.
Around 2-3 times better improvement than what I feel after every 5000km service.
(I am more sensitive in this area. After every car service, I can feel improvement even though my wife didn't tell me she just serviced the car.)

Result (Fuel Consumption):
Really small savings - negligible.
BUT I do get better power and quieter engine.
And as IceCube had suggested, I do tend to drive faster.
Cos after installation, going 100km/h also not much shaking or roaring from the engine, tot it was just 60km/h.

Conclusion:
Must buy for all few-years-old car.
Even like my Kelisa here, every 5000km sure service, but can also feel improvement.
After all, this Power Booster is really cheap!

Performance improvement depends on cars I think.
If your car is already highly optimize for performance, this thing won't help you much.
So new cars probably don't need this except chaplang brand like Proton and Perodua.

Fuel saving depends on style of driving.
If you are the kind who always drive under-powered (should be using 1st gear but using 2nd gear etc..), this might save you some fuel.
(My mum does this, cos lazy to change gear.)
If you drive 1.3 or 1.0 car and always need to climb hills/bumps, this might save you some fuel.
If you/thermostat turn on your car air-cond and you engine shudders, this might save you some fuel.

But if you always feel that your Proton/Perodua can outrun that stupid BMW 5 Series anytime, then this won't save you any fuel.

Remember me? Now need one for Iswara. Where can you COD? I'm in Seri Kembangan.
