Hey guys! I posted here a little while ago about an RX-8 I got from my aunt, and I got a lot of really helpful advice from y'all. I went ahead and replaced the spark plugs, ignition coils, the wires, and I put a can of Seafoam in my gas. My car is running a million times better so far thanks to y'alls help. My car is running pretty cool and all my fluids look alright. What should I upgrade/look at next? Any specific areas I need to clean? I've done some research, but I'm pretty short on time so I want to make sure I'm using my time on the most critical things. Sorry if I'm asking a common question. Thanks so much!

Good to see another 8 being cared for.

When were the manual trans fluid, brake/clutch fluid, and coolant last replaced? Could change those if they've never been done before.

Look into premixing if you want.

As far as I know they've never been changed. Do you recommend the coolant suggested in the newcomer thread? I'll research the best trans/brake fluid. Thanks!

I would flush the coolant if you don't know if it's been done before.

As for MTF, I recommend the Motorcraft(Ford) XT-M5-QS synthetic manual trans fluid.
