Honda 3.7L (223 cu in) firing order — what is it?
Unravel the mechanics behind the Honda 3.7L firing sequence.
As one of the most recent V6 engines developed by Honda, the 3.7-liter engine is widely regarded as powerful and reliable. However, there comes a time when you may need to know the Honda 3.7L (223 cu in) firing order to deal with some minor issues like misfires or maybe just to check the spark plugs.
Well, if that’s the case, don’t worry about it since our team of experienced automotive experts will guide you through it. This article will get you familiar with all the important specs related to the firing order and explain the importance of it together with the sequence to help you out.
Honda 3.7L firing order
Knowing the firing order of this engine doesn’t only help switch the spark plugs on time, but also deal with tune-ups, coil packs, and looking for oil residue. So, the Honda 3.7L firing order is 1-4-2-5-3-6, and it’s the same sequence in which the cylinders of their order “J” V6 engines are firing.
While that can be somewhat of a relief since you can’t misplace the firing order of this engine with any other V6, there are some unique things about this engine. It uses a complete aluminum block and that includes the cylinder liners that are made of the same material.
While we are at the cylinders, you also need to know the layout of the cylinders in this V6 engine to properly settle any issues, so let’s get to the next step.

Another relieving thing about this engine is that it uses the same base engine block as the 3.0-liter or the 3.5-liter V6. So, Honda went with a similar cylinder configuration with cylinders 1, 2, and 3 being in the left cylinder bank, and cylinders 4, 6, and 6 being in the right one.
Of course, we are talking as if you are looking at the engine from outside the car, so the right cylinder bank would be on the driver’s side from inside the cockpit. That being said, the first cylinder is on the passenger’s side and it’s the front-most cylinder if you look at it that way.
It’s important to know the cylinder numbering for this engine since it helps follow the firing order to check up on each cylinder as it fires in the combustion cycle.
