1. K&N Air Filter - Performance air filter; promotes better air flow (i.e. more efficient and effective than nomal paper filters. Hence resulting in more oxygen entering the engine so that fuel burns more efficiently. Also last longer, no need to change so often. Looks cool in the engine bay too. Conclusion: Increase horsepower and better fuel economy
2. Cold Air Intake (CAI) - Basically a device to bring in lower temp. air into the car's engine (basically funneling cold air to the air filter). Works the same as for #1, to increase horsepower through better efficiency. Theory is cooler air has higher density (greater mass per unit volume), more oxygen.. better combustion.
3. Heatshield - To attach to the air filter to keep out hot temperature around the engine bay area. Basically keeping the air as cool around the air filter area.
4. Iridium spark plugs - Last longer (no need to change so often). Improved ignition or combustion as the Iridium tip diameter is smaller than that of a standard plug hence reducing the likelihood of 'spark jump'. Hence supporse to increase power. IMHO, very marginal as new engines nowadays are very efficient. Want to buy 'cos it can last for 2 yrs without changing. The ones I'm using in my car 3 yrs already and still running well
5. Strut bar and lower arm bar - Better stability when cornering, in theory. For me, cool effect. When ppl open my engine bay. got that piece of metal from Ultra Racing..haha!
I'm a minimalist in terms to exterior mods.. prefer to keep it in the engine bay.
hehe this is what i call performance in discreet. thumbs up!

unlike those beng beng exaggerate exterior mods kononnya no powah, the exhaust macam chocking to death...
