GRUPPEM RAM AIR SYSTEM FOR TOYOTA GR COROLLA GZEA14H RHD G16E-GTS FR-0145
The GruppeM Ram Air System (FR-0145) is a purpose-built carbon duct intake for the Toyota GR Corolla (GZEA14H) — G16E-GTS 1.6L turbo.
Below is a concise product overview, what to expect, and buying/ fitment notes.
Quick facts
- Product: GruppeM Ram Air System — Part No. FR-0145.
- Fitment: Toyota GR Corolla (GZEA14H), engine G16E-GTS 1.6 TURBO (2022-on). Right-hand drive (RHD) only (LHD not tested).
- Construction: handcrafted carbon fibre duct + insulated filter housing.
- Spare / replacement filter: GMR-0945 (listed by suppliers).
What it does / benefits
- Routes cool ambient air directly to the intake, blocking hot engine-bay air with the carbon duct → lowers and stabilises intake air temperature. That improves torque and power across the rev range and sharpens throttle response.
- Produces a sportier intake sound at higher RPMs (typical of high-flow ram/intake systems).
- Bolt-on design, handcrafted for precise fitment (expect professional installation for best results).
Realistic expectations
- This is a high-quality cold/ram-air style system that helps reduce intake temps and improves transient response — you’ll typically feel snappier throttle and some additional torque/ power, especially at higher RPMs. Don’t expect massive HP gains without supporting mods (larger turbo, fueling, and/or ECU tuning). For peak gains, pair intake upgrades with an appropriate tune.
Fitment & installation notes
- RHD-specific — confirm your chassis code and RHD/LHD configuration before ordering.
- Lead time from Japan sellers often quoted (~3–5 weeks from some vendors). Shipping and customs will add time/cost.
- Installation is bolt-on but may require careful routing and removal of some trim/bumper pieces; recommend a shop familiar with GR Corolla installs. Aftermarket intake may slightly affect MAF readings — monitor for fault codes and consider a tune if you plan further mods.
Pros / Cons (short)
Pros
- High-quality carbon construction, looks and insulation.
- Lowers intake temp / better throttle response.
Cons
- Premium price vs simple cone filters.
- RHD-only fitment limitation for some buyers.
