    Hi kelvin, I was searching for Voltage Stabilizer and eventually bump to your webpage. I find out many interesting post and decided to read all of them. Since your car is no longer under warranty and you are servicing at regular service centre. Why not try getting a drop in airfilter like (K&N, BMC, Simota etc). They comes with a higher initial cost but once you installed no longer need to replace airfilter anymore. Just clean the airfilter yourself every 30000 to 40000 km using the cleaning kit bundled together. Besides than you will notice an immediate hp gain and lower fuel consumption. I notice this in my 1.3 Proton Saga which gets lively with this simple mod. Since no any exhaust component is modified the stock ECU & O2 sensor will manage to compute the air-fuel ratio accordingly.

      Hey Aviniysh,
      Thanks for drop by and read my posts!
      And thanks for the proposed K&N air filter! I am thinking that long time ago but wasn’t in budget at that time.
      I will upgrade the air filter soon, stay tune and hope to see around again 🙂
