I love RockAuto but often find Amazon to have huge savings over RockAuto on DELPHI and ACDELCO parts.

Here is an example: DELPHI Part # FJ10565 **#FJ1056511B1}
SCPI to MFI Conversion - Complete Assembly (fuel injection system for GM 4,3L

RockAuto: $241.79
Amazon: $174.01

I ended up purchasing the above from Amazon. Factory sealed box, no issue. I have found the above price savings on amazon to be common on many parts. Found similar savings on MAFs, EGRs and many other parts.

If price is important, punch the part number into Amazon, might be well worth a minute to check.

have to do the pn search because their car search is terrible

Yes, do the research on RockAuto then punch in the part number on Amazon.No issue as you have to go to both sites anyways to compare prices, I simply start on RockAuto, id the part number, then go to Amazon and punch in the part number...
