Car Mods: 1st Gen Perodua Myvi Mod Tips Part II

And to start off the month of February we take another look at what can be done to one of the most common car in Malaysia – the Perodua Myvi. Note that if you owned one or intend to own one, you would be similar to a whole lot of Malaysians who own different variants of it (probably hundreds of thousand people including yours truly) and there is nothing really unique about it even if you spend thousands of Ringgit on it. So what you need to do is make it more drive-able instead of focusing too much on cosmetics. That’s what I would do to a car that is really common – a nice compact supermini, with decent packaging and ample poke for the highways (but again I state, its no sports car).

So aside from stating the obvious above, what should you do to improve its driveability? Let’s start with more affordable mods, this time to the induction system of the car. Note that this basic mods also apply to the latest, 2nd generation Myvi too.

One simple mod that in my opinion is necessary is to the air-box entrance of the Myvi. The thing about the stock car is that the inlet tube basically sits at the right side of the engine bay right behind the headlights. There is no direct cold air feed to it and it basically sucks up hot air from the engine bay. Hot air is less dense that cold air and this means that the Myvi will actually suck in less air on a hot day or during traffic jams than on a cold day. And even on a cooler day, it would still suck up hot air that resonates from the engine as it gets its air from inside the engine bay. Get it?

So what it really needs is something to shield the intake from hot air or something to direct cold air to the intake. I have decided to feed the intake with cold air by using a flexible plastic hose (which you can buy at most performance parts shops in the Klang Valley) that I simply made fit (not a proper fit) one end around the original Myvi intake tube and adjusted and put the other end through the hole found at the right side of the engine bay (which leads to the right fender of the car). This tube is slightly directed deep and slightly low into the fender. Not too low as you may drive through floods and whatnot.

This simple tube allows the air intake to suck air from an area that is cooler than the engine bay. I chose to use just the plastic flexible length hose instead of with the alloy ends for the stealth look as I didn’t want to mount the intake to the bumper. Note that because of this there is no ‘ram-air’ effect but I do not think that such a thing is necessary for a car like this. It isn’t a track car and if you look at the standard air-box, which is located transversely but the throttle body is located vertically and facing downwards, ram-air would not help by much.

So does it work? I honestly don’t actually know but what I can say is that it does feel very slightly more preppy during when accelerating through heavy traffic. It still doesn’t feel like driving on a cold rainy day, but it is slightly better nonetheless.

Now since we are at the intake section, the next mod that you can do without spending a whole lot of cash is a drop in or replacement air filter upgrade. Six clips will open the air-box and you can get your hands on the stock air-filter. I chose a UTR washable replacement air filter to replace it. The reason I chose this over the venerable K&N air filter was that it is cheap. It costs half as much as the K&N and works just as well – 1bhp increase to the Myvi.

This figure is according to my friendly neighbourhood parts supplier – Mr Tee of Sykt Multi Industries, located at Paramount Gardens, PJ. How he got such figures is that some of his customers have too much time and a lot of money as they will dyno their rides after every little ‘upgrade’. He however adds that the K&N will actually last longer than the UTR filter as that really lasts over 5 years whereas the UTR may give up the ghost in 3years or so. You pay for quality. Remember this. I on the other hand have too many hobbies (shoes, watches, bicycles, cars, travelling etc etc…the list is endless), hence me being cheap when it comes to modding the Myvi. At least you readers get to find out whether the cheaper parts work or don’t. In this case it does.

Throttle response is slightly better when you first drop it in but after a day of driving you won’t feel any difference. This plainly shows that 1 measly bhp will not get you all excited for long. But at least you don’t have to change the air filter often. So there you have it. Another two affordable mods for one of the most common car owned around these parts.

What’s next you may ask? I’d have to say brakes. The stock brakes actually suck big time. A full stop from 120km/h takes too long a distance. Trust me. And anytime I see a Myvi going more than 120km/h I worry about them.  In the Myvi you cannot SLOW DOWN quickly enough at speeds in excess of 120km/h. If you tell me your Myvi can reach 180km/h, I believe you. But can you stop properly at 180km/h? You actually cannot. Trust me on this.

On that bombshell we end this article. The next step for the Myvi is upgrading the braking system before we go to more power upgrades.

  1. Thanks for the series. Will you be continuing to part 3? Also, does what you are recommending here apply to the Myvi 1.5 as well?

  2. Hello,
    There will be a part 3. Yes it does apply to the 1.5. But some parts are slightly different. Like the front strut bar, the 1.5bar is slightly different due to the taller engine block. The 1.5 gets its extra 200cc from the stroke of engine, which is why its taller.

  3. hi sir… i’m wondering if u can explain more on how to fix the plastic hose for the air intake onto the engine bay? i dont really get it. ur help is really much appreciated. thanks!

  4. 1. buy the hose in the picture.
    2. remove metal ends
    3. there is a hole at the side of the fender – right where the original air intake lies
    4. force one end into the hole so that you get air from OUTSIDE of the engine bay instead of hot air from the engine.
    5. stick the other end onto or over the original air intake

    I do hope this answers your question.

  5. I’m getting a used myvi and you basically gave me the idea of what I need to deal with. Thanks! -Aiden

    1. Hi, If you want a more comfortable ride for the Myvi I could suggest changing it to another car. But seriously, add the strut bar then add the rear anti roll bar like I stated in here – http://motoring-malaysia.blogspot.com/2013/10/car-mods-1st-gen-perodua-myvi-tuning.html

      Adding both will ensure the suspension to work properly as there is a heck of a lot of flex in the chassis (the car is actually rubbish). If the ride is still bad then I’d suggest keeping the standard 14inch wheels and tyres but add a set of adjustable coilovers and run it with the softest setting allowed. But not too soft as then the car will be unable to handle cornering properly. Its all about balance. And Cost. The Myvi was built to a very low cost point. If you want a good example of how a small supermini rides and handles, try the Suzuki Swift. Regards,

  6. Thanks to the author. I salute you. These are great advise for new MyVi owner. I just bought a 2008 SE and I have added the strut bar but has not do the rear anti roll bar yet. Can already feel the difference. Also has change out the stock air filter to a metal washable air filter. Can feel the difference in the beginning but later still feel ok la. If want to feel the torque again, I just wash the filter regularly. Will also get the brake pad and disc done soon because my mechanic test drive my car 1st time can already tell the brake is crappy. Also has upgraded to 15″ OZ rim and dunlop tires. Will do the air hose intake later. Thanks again sir for the great article and advise.
