The Ford 5.4L Triton V8 is the middle engine in the Ford Modular engine series. The 5.4 Triton was released in 1997 and designed to be the next Ford F-Series powerhouse to replace the 351 Windsor. When the Ford 5.4 V8 first arrived under the hood of the Ford F-Series, it utilized a SOHC 2-valve design. Over the next five years, Ford added additional 3-valve and 4-valve variants to the 5.4 Triton lineup.
The firing order of an engine is an important thing to know for a few reasons. If you are doing any modifications that have to do with ignition timing, you’ll have to be conscious of the firing order of your 5.4 Triton. This goes for tune-ups, cam upgrades, and other similar modifications. Knowing cylinder locations is also important to know in case your 5.4 throws a code for a specific cylinder.
Keep in mind, the firing order of an engine is different from knowing each cylinder’s numbered location. Since the purpose of a firing order is to balance out engine vibrations, the sequence on V8 engines, including the Triton, alternates between the left and right banks of the engine in a pattern that causes the least stress on the crankshaft.

Ford 5.4 Triton Firing Order
The Ford 5.4 Triton firing order is 1-3-7-2-6-5-4-8. We’ll provide a visual aid for this below, but the Triton’s cylinders are numbered sequentially by bank. The cylinder bank on the passenger’s side is numbered 1 through 4, with cylinder number 1 being closest to the front of the vehicle. The cylinder bank on the driver’s side is numbered 5 through 8, with cylinder number 5 being the closest to the front of the vehicle.
This firing order applies to all of the V8 engines in the Ford Modular engine series except one. The 2011+ 5.0L Coyote V8 has a different firing order of 1-5-4-8-6-3-7-2. The 5.4 Triton’s 1-3-7-2-6-5-4-8 firing order is also the same as the older Ford 5.0 L HO and 351 CID.

Ford 5.4 Triton Spark Plug Issues
While it isn’t directly related to the 5.4 Triton firing order, it is important to note that the 5.4 is notorious for having spark plug issues. Pre-2002 versions of the 2-valve engines are prone to having spark plugs blow out of their holes and damage the cylinder head. Older 2004-2008 3-valve engines are prone to having the plugs break during removal. Ford fixed the issues in later versions of the engines. The primary solution to 5.4 Triton spark plug problems is to simply change them at a more frequent interval.
