Before that do note that there are 2 kinds of 70mai TPMS, mainly know as 70mai TPMS lite(external sensors) & 70mai TPMS(external), the ones you'll widely see in shopee or lazada are the external one, the one i've installed is the internal ones.

For internal sensor like mine, installing will be more troublesome as you need to actually go to tyre workshop; best let professional do it (I don't recommend those DIY installation videos in youtube, do it at your own risk). But in return it's all worth it... read on.

Alright, here's what you get in the 70mai TPMS package:


and here the actual sensor unit break down diagram that i cincai drew to further elaborate which will be mentioned in later:


I got mine from shopee locally for RM250 which is average price shipping not included. 3 days later, and i received mine:

first thing i did is removing the sticker from the valve stem and relocate it, if you intent to install the TPMS as it is, i do relocate the stickers as once the valve stem is tighten into the wheels removing the sticker will be troublesome. Then you'll need to first charge display unit itself, then at the same time you can download the app
i'm using android so i went playstore to get it.

Here an up-close of the valve cap and valve stem nuts
well i do not like those, it felt very cheap and the color, is a big no no for me. Definitely does not match our stock tyre, especially mine. Well good news, these items replaceable and are available in shopee, just go look for nicer valve stem, example rays valve stem those are fairly cheap. Do note that you won't be able to replace the whole valve stem, just the valve cap and valve nuts, the valve core i can't find any matching replacement. (refer to the previous diagram i drew)

so i got a replacement those ugly cap by using these:


so all set and I let tyre workshop tauke to install.

I guess it's a bit too long i'll post it on part II
