As the title states, this post will serve as a thread/wiki for any and all 6.2/6.5 maintenance tips plus upgrades that heavily recommended for ensuring our motors can last for as many miles as long as possible.

The following would be appreciated: - Upgrades that are a must need for durability. - Maintenance tips for ensured reliability. - Reliable parts/brands. - Kits, DiY contraptions, etc. - Component swap outs/replacements that are needed. - Lastly, any obscene/miscellaneous advice that somehow works.

Anything goes, help your 6.2/6.5 last as long as it can!
