Maintenance Items: OEM or Aftermarket?

[HAULN-SS]

I usually just do a ton of research on any part that's more than 200$. Some things you can't go wrong with OEM. For example, the vortech headers I put on my SS were 500$ for both of them, and have good flow numbers, compared to paying that much for EACH for aftermarket heads.

For water pumps, fuel pumps, etc..just be prepared to take it back to AAP or wherever, but you're probably getting a rebuilt OEM core anyway, and its easy to take back for a repair..if you're doing it yourself you're just out your time for the swap.
