Honda Ridgeline Engine Replacement in Phoenix
A pickup truck that has always used the J35, but the generation decides whether you have port injection or direct injection, and those are different engines.
The Ridgeline is Honda's pickup truck and it has used the J35 V6 since its introduction in 2006. The first-generation Ridgeline (2006-2014) used the J35Z5, a 3.5-litre V6 with port injection. The second-generation (2017-2023) moved to the J35Y6 with direct injection and revised intake architecture.
Those are meaningfully different engines despite sharing a family designation. The direct-injection J35Y6 has a different fuel system, different intake manifold and different calibration. A first-generation unit will not run correctly in a second-generation truck without addressing those systems, and the reverse is equally true.
The Ridgeline's unibody construction and integrated bed make it a different vehicle from a mechanical standpoint than a conventional body-on-frame truck, but that does not change the engine conversation. What does change it is the generation and whether the vehicle is all-wheel drive, which affects the transfer case and supporting hardware.
Port injection versus direct injection
The first-generation Ridgeline (2006-2014) used the J35Z5 with port injection; the second-generation (2017-2023) used the J35Y6 with direct injection. They share a family designation but differ in fuel system, intake manifold and calibration. A first-generation unit will not run correctly in a second-generation truck without addressing those systems.
The Ridgeline's unibody construction does not change the engine conversation, but the all-wheel-drive option does. AWD Ridgelines have additional transfer case hardware that front-wheel-drive models do not have, and that should be part of the ordering conversation even though the engine block is the same.
The generational change is significant
The first-generation J35Z5 uses port injection, a conventional fuel delivery system where the injectors sit in the intake manifold and spray fuel into the intake runners. The second-generation J35Y6 uses direct injection, where the injectors sit in the combustion chamber and spray fuel directly into the cylinder. These are different fuel systems with different fuel rails, different injectors and different engine management.
Because the fuel system is integrated into the engine, a J35Z5 from a first-generation Ridgeline is not a viable replacement for a second-generation truck without reworking the entire fuel delivery system. That is not a cost-effective path. Confirm the stamped code on the engine and the generation before ordering, because the family code alone does not tell you which fuel system you are dealing with.
What to have ready when you request a Ridgeline engine
Generation first. The J35 variant changes between the first and second generations, and the fuel system difference means these are not interchangeable. The model year is usually enough to establish the generation, but the stamped code on the block is the definitive confirmation.
Drivetrain: front-wheel drive or all-wheel drive. The Ridgeline was sold in both configurations, and the supporting hardware around the engine differs between them. AWD models have transfer case and driveshaft hardware that front-wheel-drive models do not have, even though the engine block is the same.
Transmission type. The Ridgeline used different automatic transmissions across its production run, and the flex plate and torque converter arrangement differ between them. Confirming the transmission type along with the generation prevents the kind of order that fits the block but does not match the drivetrain.
Where Honda Ridgeline orders go wrong
- The J35Z5 and J35Y6 are different engines with different fuel systems; the generation decides which one you need.
- First-generation Ridgelines use port injection; second-generation models use direct injection. These are not interchangeable without addressing the fuel system.
- All-wheel drive Ridgelines have additional transfer case hardware that front-wheel drive models do not have.
None of this needs to be worked out on your own. The Engine Finder asks for the year, model and trim and does the identification from there. The engine code field is optional precisely because most people do not have it.

Common questions
Which J35 does my Ridgeline have?
The first-generation Ridgeline (2006-2014) uses the J35Z5 with port injection. The second-generation (2017-2023) uses the J35Y6 with direct injection. They share a family name but they are not the same engine. Supply the year and VIN to confirm which variant you need.
Is the Ridgeline engine the same as the Pilot engine?
They share the J35 family but not necessarily the same variant. The Ridgeline used the J35Z5 while the contemporaneous Pilot used the J35Z4, and later models diverged further. The accessory layout and mounting may also differ. Supply the VIN and let the supplier match the application rather than assuming the shared family code means the same part.
