| While the engine is bone stock and even retains the OEM ECU, there were some minor changes under hood for safety and further reliability. For safety, a full HALON fire system is installed that shoots out fire retardant on all critical places like the fuel tank, engine, and driver's compartment. |

An oil cooler system was also added, but in order for it to work the filter drain had to be modified. While it's great that Toyota/Subaru put the oil filter here for easier access and give you a better way to drain the filter, it does lead to inconvenience for the would be racer who wants an oil cooler. Nothing a good old Dremel tool can't take care of. Three well placed cuts and you're done! The APM Racing FR-S also uses an off the shelf Koyo Radiator to keep the car cool. It may have been too much as they never saw temperatures above 170 F! It's also using the OEM Air Filter and Oil Filter. |

| An NR-G Oil Catch Can was also added to replace the OEM PCV system and address any chances of oil blowby or too much crankcase pressure. |
 |
| To address the need for better lighting during the night sessions, APM retrofitted an HID lighting system to the FR-S. Unfortunately during the race contact was made at the front end which cut into the wires for the ballast. It only affected the one side. |
 |
| Looking to the exhaust, once again there's nothing too exotic. However, while the OEM front catalytic converter was retained… |
 |
| The rear was removed using this Mid-Pipe by DC Sports. DC is going to be making a header for the FR-S/BRZ this year, possibly in January or February. |
 |
| DC Sports also fabricated the rest of the exhaust system for the FR-S. That's the OEM Torsen differential too! |
