Which Engine Is in My Infiniti Q50 or Q60? VQ37VHR vs VR30DDTT Parts Guide
Share
"Q50" and "Q60" cover more than one engine, and ported intake parts are engine-specific. A VQ37VHR plenum won't bolt to a VR30DDTT, and the reverse is also true. Before you order, confirm which engine your car has.
The quick version
| Car | Engine | Parts to shop |
|---|---|---|
| 2014–2015 Q50 3.7 | VQ37VHR (3.7L V6, naturally aspirated) | VQ35HR / VQ37VHR |
| 2014–2015 Q60 (formerly G37 coupe and convertible) | VQ37VHR | VQ35HR / VQ37VHR |
| 2016–2026 Q50 3.0T, including Red Sport 400 | VR30DDTT (3.0L twin-turbo V6) | VR30DDTT |
| 2017–2024 Q60 3.0T, including Red Sport 400 | VR30DDTT | VR30DDTT |
| Q50 Hybrid | VQ35HR with a hybrid system | Ask us before ordering |
| Q50 2.0T / Q60 2.0T | 4-cylinder turbo | We don't make parts for this engine |
How to tell which engine you have
- Look at the badge and paperwork. The model year and trim on your registration or window sticker (3.7, 3.0t, Red Sport 400) settle it in most cases.
- Open the hood. The VR30DDTT is a twin-turbo engine, so you'll see charge piping running to two throttle bodies. The VQ37VHR has a naturally aspirated intake with no intercooler piping.
- Still unsure? Send us your VIN or a photo of the engine bay and we'll confirm before you buy.
VQ37VHR (2014–2015 Q50 3.7 and Q60)
The 3.7 is the same engine family as the 370Z and G37. It shares our ported intake parts with those cars:
- Ported VQ35HR / VQ37VHR intake plenum and lower intake manifold, ceramic painted in the color you pick
- Ported and ceramic painted VQ35HR / VQ37VHR throttle bodies
- Custom color aluminum valve covers

VR30DDTT (2016+ Q50 3.0T and 2017+ Q60 3.0T)
The VR30DDTT makes 300 hp stock, or 400 hp in Red Sport 400 form. It's a different engine design from the VQ, with its own intake parts:
- VR30DDTT ported intake manifold: runners opened up approximately 3mm
- VR30DDTT ported intake plenum: lower runners ported approximately 3mm, throttle body openings enlarged approximately 2mm
- VR30DDTT manifold and plenum package: both parts for less
- VR30DDTT ported and ceramic painted throttle bodies
The 3.0T manifold and plenum are plastic, so we port them and leave the factory finish. Only the throttle bodies are ceramic painted. More detail is in our VR30DDTT manifold and plenum guide and our Red Sport 400 throttle body guide.

Every ported part is made to order and usually ships in 2–3 weeks. If you're not sure what fits, ask a VQ expert before you order.
