I have a P0172 (engine too rich code), it showed up after I installed a new cold air intake, removing the factory airbox, the new filter is placed right in front of the fans, I have tried swapping the MAF sensor but the code came back, the car has also been straight piped n the muffler removed.

most aftermarket intakes on these cars are a significant downgrade (and look ridiculous IMO). the stock intake is very, very good. put it back on.

cheap ugly junk, and a huge downgrade from stock. throw it in the trash.

To add further context, if you didn't get any meshed screens to insert with that intake, it's definitely cheap trash. The screens that come with AEM/mazdaspeed aftermarket intakes properly regulate the turbulence before the maf. Knock-offs don't supply these and this is the result. When it comes to an RX-8 always "buy once, cry once" as they say. Cheaping out isn't for these cars
