PRODUCT DETAILS
RallySport Direct now carries a great selection of quality high-performance upgrades brought to you by Grams Performance and Design.
Here, you are looking at the Grams Performance 72mm Drive-By-Wire Throttle Body. This is a high-performance direct bolt-on upgrade over the factory restrictive throttle body. The Grams Performance unit does not require swapping electric motors, wiring, or mounting adapters, and each unit is not re-manufactured. Each throttle body includes all new components including a CNC machined billet 6061-T6 aluminum housing with a precision-honed oversized bore, a responsive high-torque servo motor, and a proprietary Non-Contact Hall Effect TPS Sensor.
DETAILS:
- 50% increase in airflow over the stock 64mm throttle body
- Precision-honed oversized 72mm bore (+7mm over stock size)
- CNC machined billet 6061-T6 aluminum body
- Aluminum throttle plate
- Factory programmable non-contact hall effect TPS
- Optimized TPS response curve
- High-torque precision servo motor
- Thermal gasket
- Throttle body adapter
- Plug and play installation
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
