JDM TUNING, AMERICAN AVAILABILITY

Yes, Greddy is widely respected in the performance space — GReddy (TRUST) is one of the oldest Japanese tuning brands, founded in 1977 and known for its motorsport heritage in JGTC and time attack. On MOTORMIA, 1,402 Greddy parts span intercoolers, intake manifolds, oil coolers, and exhausts, with 3,000+ active member builds running Greddy components. For most performance buyers, Greddy is considered worth the price premium for its combination of street manners and durability under load.

Greddy offers fitment across a wide range of platforms. The most-installed Greddy fitments on MOTORMIA are: Nissan Skyline, Mazda RX-7, Mitsubishi Lancer, Scion Fr-s, and Mazda Mazda6. To confirm exact compatibility for your specific make, model, year, and submodel, use the fitment selector at the top of any Greddy product page — the catalog cross-references Greddy's part numbers against verified factory specs.

Both. Greddy's Spectrum exhaust and bolt-on cooling lines are engineered for street use — bolt-on cooling upgrades, weld-on intake manifolds, and Spectrum exhaust systems. The TRUST intake plenums and racing intercoolers lines are track-focused, with race-spec intercoolers, oil thermostats, and forged plenum spacers, and remain street-legal but are optimized for repeated heavy use. Most MOTORMIA members running Greddy daily choose the street line. Each product page tags the intended use so you can match the part to how you actually drive.

Greddy and HKS are both top-tier performance brands. Greddy is intercooler and intake plenum specialist with deep JDM heritage, while HKS focuses more on turbo systems and ECU tuning. On MOTORMIA, Greddy parts average $1,040 across 1,402 SKUs. The decision usually comes down to budget, brand preference, and which product line has a direct fit for your specific chassis.

A typical Greddy install takes 2–5 hours with depending on the part — intercoolers and oil coolers in 2–3 hours, manifolds closer to a full day. Each product page lists torque specs, required tools, and any vehicle-specific gotchas. If you've done similar work before, a Greddy install is a weekend job. If this is your first time, a professional shop install is a safe choice for parts that affect braking, steering, or fuel-system pressure.

Yes. Most Greddy parts on MOTORMIA are eligible for our standard 30-day return policy provided they're unused, uninstalled, and in original packaging.
