Best Ignition Coils for Ford F150 EcoBoost in 2027

This kit is built for the 3.5L EcoBoost V6. The listing names the F-150, Explorer, Expedition, Flex, Taurus and Transit models, and the model name points to 2011-2016 F-150 trucks. It lists the UF646 and DG549 coil numbers. It also says the kit does not fit the naturally aspirated 3.5L, so check your engine first.

The pack count is 12 pieces. That is six coils and six pre-gapped iridium plugs, so one box covers a full V6 tune-up. This is the highest piece count of the nine products on this page. The maker lists a 35 kV secondary output for each coil. The listing calls it plug-and-play, so no changes should be needed.

Misfire is the problem most buyers are chasing. The listing ties worn coils and plugs to misfires, rough idle and codes P0300-P0308. It adds a 2-year warranty and says the coils ship with green dielectric grease. Torque the plugs to 15–19 lb·ft. Check the part numbers against your old coils. It also offers lifetime technical support.

This set ranks second on our spec score, but it is the wrong product for an F-150 EcoBoost. Treat its rank as a spec score result, not a fitment match. It is made for Chevy and GMC V8 trucks and SUVs, such as the Silverado, Sierra, Tahoe and Yukon. The listing never mentions Ford. Do not buy it for a 3.5L V6.

The numbers show why. Engine size runs from 4800 to 7000 cc, and 7000 cc is the highest on the page. A 3.5L EcoBoost is 3500 cc, below that range. The kit holds eight coils and eight platinum plugs with eight wires, which is two more coils than a V6 uses.

The coils are square UF413 units with four terminals, a 12V rating and a 6.8 lb kit weight. The listing warns that a round UF414 style also exists. Each pack is bolt-on, with a 12-month warranty. These are fine details for a GM owner. For a Ford owner, they matter only as a reason to keep looking.

This ENA set targets the same job. The listing names the F-150 for 2011-2014 and 2015-2016 with the 3.5L V6. It also lists Explorer, Expedition, Flex, Taurus SHO, Transit and Lincoln models. Fitment depends on the connector. It fits the turbo EcoBoost 3-pin type only. A 2-pin or naturally aspirated engine will not fit.

The kit holds six coils and six iridium plugs, so it is a complete V6 set. The kit weighs 5.1 lb, against 4.12 lb for the autoexact kit, which also holds six coils and six plugs. The coils mount on the valve cover and run at 12V. The plug gap is 0.039 in.

The maker does not publish an output voltage for these coils, so you cannot compare spark strength with the autoexact kit. The warranty is 12 months, against 2 years on the leader. The listing also states the reference numbers UF646 and BL3Z-12029-A. It ranks third on our list. The listing urges using the Confirmed Fit tool with your vehicle details.

This is a motorcycle coil for 2-stroke and 4-stroke dirt bikes and ATVs. It covers 50 to 350 cc engines. A Ford 3.5L EcoBoost is 3500 cc, so it is far outside that range. The listing does not mention Ford trucks, and nothing in it suggests a fit. It ranks fourth on our spec score, which says nothing about truck fit.

On paper it has real strengths for its own job. The 56.8 kV output is the highest of the three products that list voltage. At 0.42 lb, it is the lightest of the eight that list weight. The listing says it fits 6V, 12V and 24V CDI systems.

It is sold as a single piece, so a six-cylinder engine would need six separate units. The listing shows no spark plug and no fitment for car coil-on-plug systems. The coil's total length is 42 cm and the excess can be cut off. Buyers also get contact support, offered before and after purchase.

These coils are a set of six, but they are made for Honda and Acura V6 engines. The listing names the Odyssey, Accord, Crosstour, TL, TSX and RL. It does not name any Ford or Lincoln model, so it should not be used as an EcoBoost replacement. Ford truck owners should look at the first or third product instead.

The engine size range is 3500 to 3700 cc. The Ford 3.5L sits at the low end of that range, which can look like a match in a quick search. Size alone does not decide fit. Connector shape, mount and coil height must match too. Here the listing ties its three terminals and valve cover mounting to Honda applications. Match the part number, such as UF-603, to your old coil.

The kit weighs 3 lb. It includes no spark plugs, so you would source plugs separately. The warranty is 12 months. The listing describes the coils as black and bolt-on. It ranks fifth on our spec score, which reflects specs and not truck fit.
