First of all, it's nitrous oxide, not nitro oxide.
You need management to use this and it will result in serious wear and tear if used long term. Insanely satisfying and addictive to press the 'happy button' and insanely expensive to refill the NOS bottle. Something like RM200 to RM400 per refill and a 'normal' bottle will last you about 10 short shots of 'happiness'.
So if you have money, go for it. Great way to have instant 40whp increase. If you go to GT Auto to do your dynos and if Thomas is in the mood, he'll bring out the NOS bottle during one dyno run and make your car go seriously faster with the NOS.
A friend had it installed on his tricked out Wira but after demodding, he found a lot of badly worn out internals which were suspected caused by his constant boosting with the NOS trigger button. Gave up the NOS after 2 months cuz he complained the refill was costing him more than RON97 petrol + ciggies put together (he doesn't smoke though).
But gotta love that stick to kerusi feeling.
