Replacing my fuel injectors soon and have some questions i haven’t found the answers to…

for context, i have a 2003 S10 4.3l v6 and i plan on replacing my fuel injectors and im trying to find a reliable part replacement. i saw on rockauto a brand new system with the MPFI fuel injection type and ive seen on some posts that its a better upgrade to the SCPI fuel injection type.

i need this really soon so im looking on autozone. this specific part: GP Sorensen Fuel Injector part # 800-1512N
i’ve seen mostly good reviews on this and was wondering if it would be okay. some pointers would be great on what the best approach would be on buying the correct part so it doesn’t fail on me a few months after replacing 🥲

i know exactly how to get to them because i’ve done a replacement on an older model s10 that i used to own.
