Service and some improvements for my NEO

My car's air filter were VERY dirty or even clogged and the car reached service mileage.
I feel that I have the budget to spend some money to improve the performance and fuel efficiency.

1st item to change - Engine Lubricant:
After DIY the Lubricant Flushing, it's time to pour in a new set of lubricant oil.
The Oil (F4 Pro 10W-40 Semi-Synthetic) is manufactured by GReddy, a famous automotive performance OEM part of Japan.
Actually I preferred Red Line since it was proven by some Motorsports enthusiasts. But it's a way too expensive (RM50/Liter, and my car needs 4 liters). So I decided to take this, the result is quite satisfied. It's smooth in every reving range as the engine's friction has been reduced.

Next, the Air Filter:After a few of surveys, I found RedLine Performance's drop in air-filter is the cheaper and effective long-life performance air-filter, it is washable and endurable, it provides greater air flow as well.

The air flow was proved as follow,

Redline Performance Filter



The original filter was thrown as it's dirty and make cars less fuel efficient:
The result after these minor upgrades are great. The car is more willing to rev and smoother, as for the fuel efficient, I'll try them for longer period for the better accurate result. But as the performance, I can say I'd like to say I'm quite happy with it, the car turns lighter and faster in throttle response.
Thanks Joe (Red line performance +60123225649) for assisting me in these improvements.
