Juz wanna tumpang thread ....
I will be sending my Wira for top overhaul today.....

now I am just confuse on the parts. Some people say must fix original. While the mechanic said there are 1 type is better than the original but he never tells me any brand or what. I haven't been in touch with cars stuffs long enough so need you guys to enlighten me

So for all the parts, is it must be 100% original in order to prevent any problem in future later?
