Hi. Guys, just wondering, I have done my first service for my perodua myvi 2018 1.5H. I felt kena con. But learn a bit of my mistake to not take any extra stuff. Here's what I purchased for my first service:

What do you guys think? Which one is not really needed maybe the next service, i will not take them

Nitrogen Gas
Hood Insulator
Battery-Terminal Protector
Magnet Trap
Windsheild Washer

All these cost me around RM144.

Thanks.
