Top 5 Mods to Unlock Power on Your FK8
The FK8 Civic Type R (2017–2021) is a turbocharged monster from the factory, but with the right upgrades, it becomes a track-ready beast. At SBX Performance, we specialize in performance parts that deliver real gains — and we know where to start.
Here are the top 5 bolt-on mods every FK8 owner should consider:
PRL Big Bore Intake (Street or Race MAF)
Choose between the Street MAF (no tune) and Race MAF (requires a tune, more airflow).
Great options include
Eventuri
PRL
-
Street MAF: No tune required
-
Race MAF: Tune required, better performance
-
Gains: 10–15whp with tune
-
Bonus: More turbo noise 😤
👉 Pro Tip: Use the Race MAF with Hondata or KTuner and have your tuner scale it properly.

Front-Mount Intercooler Upgrade
Cooler intake temps = consistent power. Use a quality intercooler like
PRL Full Race HKS Injen
-
Reduces heat soak
-
Improves repeatable power
-
Pairs with upgraded charge pipes
💡 SBX Recommendation: Go for a core 3.5” or thicker and don’t skip upgraded couplers.

High-Flow Downpipe
Replace restrictive OEM piping with a RV6 downpipe for big gains.
-
+15–20whp with tune
-
Faster turbo spool
-
Aggressive sound
🔧 Catless setups need a tune and may trigger CELs. A custom-tuned combo is best value.

Hondata FlashPro
Tuning is key to unlocking your mods. FlashPro allows full ECU control.
-
Maximize boost, fuel, and timing
-
Data logging and limp mode protection
⚠️ Important: If you run a Race MAF, downpipe, or turbo, a custom tune is mandatory
Turbo Inlet Pipe & Charge Pipes
Inlet pipes smooth airflow into the turbo, charge pipes optimize it after compression. Eventuri PRL PLM are all decent based on your budget.
-
Improves throttle response
-
Reduces turbulence
-
Supports higher boost targets
🔥 These round out your airflow system when paired with intake and intercooler.
