Does Acura use direct injection?
Yes. Acura uses gasoline direct injection in several of its current engines, notably its 1.5-liter and 2.0-liter turbocharged inline-fours and the NSX’s 3.5-liter twin‑turbo V6.
Overview of direct injection in Acura vehicles
Direct injection (DI) is a key part of Honda’s Earth Dreams technology. It delivers fuel directly into the combustion chamber, enabling higher compression, improved precise fuel control, and better efficiency and power. Acura has moved to DI across many of its modern gasoline engines, especially turbocharged four-cylinders and high-performance powertrains. Some older engines or non-turbo variants may have used port fuel injection in earlier generations, but recent models predominantly deploy DI.
Current Acura engines using direct injection
The following examples illustrate engines in Acura’s lineup that use direct injection in current models.
- 1.5-liter turbocharged inline-4 (used in models like Integra/ILX) — direct injection.
- 2.0-liter turbocharged inline-4 (used in TLX and RDX) — direct injection.
- 3.5-liter V6 i-VTEC (used in MDX and other models) — direct injection.
- 3.5-liter twin-turbo V6 (NSX) — direct injection.
Direct injection has become a standard feature in Acura’s current gasoline engines, particularly for turbocharged four-cylinders and the brand’s performance-oriented V6. For model-year specifics, consult the official Acura specifications for each vehicle.
Summary
In short, Acura employs direct injection across its primary modern gasoline engines, including the 1.5L and 2.0L turbo four-cylinders, the 3.5L V6 found in several models, and the NSX’s high-performance V6. This aligns with Honda’s broader Earth Dreams strategy to boost efficiency and performance across the lineup.

How do I tell if my car is direct injection?
PLEASE REPORT ANY RULE-BREAKING BEHAVIOR There are three categories you can identify by look on gasoline engines. Throttle body looks like carburetor and all the fuel goes to one place. Direct injection has fuel go to the cylinder heads. Sometimes the injectors are hard to see but they are in the head itself.
