The Honda N64A is a 3,498 cc, naturally aspirated V6 petrol engine introduced in 2018 for the North American market Odyssey minivan. It features a single overhead camshaft (SOHC) per bank, 24 valves, and Honda's i-VTEC system for variable valve timing and lift. This engine delivers 280 PS and 355 Nm of torque, with i-VTEC optimizing valve overlap for a broad, flat torque curve ideal for family vehicle responsiveness.
Fitted exclusively to the fifth-generation Odyssey (RC), the N64A was engineered for smooth, quiet operation and strong low-to-mid range pulling power. Emissions compliance is achieved through direct injection, precise combustion control, and a sophisticated three-way catalyst system, meeting stringent ULEV2 and Tier 3 Bin 30 standards.
One documented engineering focus is minimizing oil dilution in cold climates, addressed in Honda Service Bulletin A18-077. The bulletin details revised engine control unit (ECU) software to optimize fuel injection timing and post-injection cycles, reducing unburned fuel entering the crankcase during short-trip winter operation.
Honda
Production from 2018 meets U.S. EPA Tier 3 Bin 30 and California ULEV2 emissions standards (EPA Certificate of Conformity #A-HON-18-N64).
The Honda N64A is a 3,498 cc V6 naturally aspirated petrol engine engineered for minivans (2018-Present). It combines SOHC architecture with i-VTEC variable valve timing to deliver smooth, linear power for effortless towing and highway cruising. Designed to meet U.S. Tier 3 Bin 30 and ULEV2 standards, it prioritizes refinement and low emissions for family use.

The i-VTEC system provides smooth, linear power ideal for highway cruising and towing but requires the specified 0W-20 HTO-06 oil for optimal VTEC solenoid and lifter operation. The timing chain is designed for life but relies on correct oil specification and level. Direct injection demands the use of top-tier fuel to prevent carbon buildup on intake valves. Cold-climate operation requires adherence to the revised ECU calibration per Honda SIB A18-077 to mitigate oil dilution.
Oil Specs: Requires Honda 0W-20 (spec. HTO-06) for i-VTEC system compatibility and optimal lubrication (Honda Owner's Manual).
Emissions: Meets U.S. EPA Tier 3 Bin 30 and California ULEV2 standards for all 2018+ production (EPA Certificate #A-HON-18-N64).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Honda TIS Doc. N64A-A26015).

The Honda N64A was developed for Honda's Minivan platform with transverse mounting. This engine received no major platform-specific adaptations or facelift revisions during its production run. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the alternator (Honda TIS N64A-A24890). The 8th VIN digit for N64A-equipped Odyssey models is 'R'. Visually, it can be identified by its 60-degree V6 layout, SOHC valve covers (one per bank), and the 'V6' badge on the vehicle. Critical differentiation from the older J35 engine: The N64A has direct fuel injectors (visible as small solenoids on the intake manifold runners) and no EGR valve. Service parts are specific to the N64A and model year.
The N64A's primary design focus is long-term reliability for family use, with minimal standalone mechanical issues reported. Honda's internal quality metrics from 2018-2024 show very low warranty claims for the powertrain. As a relatively new engine, long-term data is still accumulating, but its design inherits proven elements from the J-series. Consistent use of the correct 0W-20 oil and top-tier fuel is paramount for longevity.
