ENA Iridium Spark Plugs Set of 6 for 3.0L V6 (SP433) — Pre‑Gapped .051in, Direct OEM Replacement

These ENA iridium spark plugs are built for direct replacement in V6 3.0L engines across a broad range of late‑model Ford-family and related vehicles. The fine-wire iridium center electrode and pre-set gap simplify installation while delivering a concentrated spark pattern designed to help stabilize combustion and support consistent starts. Each box includes six plugs and a 12‑month warranty for basic coverage.

Which vehicles are compatible with the ENA SP433 set?

The ENA SP433 plugs are designed to fit many 3.0L V6 applications from Ford, Mercury, Lincoln and Mazda produced roughly between 2000 and 2011. They cover common models such as Fusion, Escape, Taurus, Five Hundred, Freestyle, Milan, Montego, Sable, Zephyr and Tribute when equipped with the 3.0L V6.

• Ford Fusion, Escape, Taurus, Five Hundred, Freestyle — 3.0L V6 model years listed in product details
• Mercury Milan, Montego, Sable — specific years indicated by fitment list
• Lincoln Zephyr and select Mazda Tribute 3.0L V6 model coverage
• Always confirm fit by vehicle year, make, model and engine before purchase

How are ENA SP433 plugs different from standard spark plugs?

ENA uses a fine‑wire iridium center electrode that requires less voltage to produce a focused spark compared with conventional nickel electrodes. The iridium tip is more wear‑resistant, which helps preserve the electrode profile and maintain consistent ignition characteristics over time.

• Iridium center electrode for longer electrode life and stable spark
• Pre‑gapped at 0.051 inches to match factory spacing and ease installation
• Fine wire tip reduces required firing voltage and concentrates the spark
• Hex size and thread dimensions match OEM replacement specifications

What are the technical specs and installation notes?

Each plug in the SP433 set is pre‑gapped to 0.051 inches and uses an iridium center electrode; thread diameter and hex size match common OEM dimensions for the listed applications. These plugs arrive ready to install but always torque to manufacturer specifications for a correct seal and long service life.

• Center electrode material: iridium
• Gap size: 0.051 in; hex: 0.63 in; thread diameter: 14 mm
• Sold as a set of six — enough for a single V6 cylinder bank or engine rebuild
• Follow vehicle torque specs and use anti‑seize or dielectric grease only when specified

Will these plugs include warranty and how do I confirm fit?

The set comes with a 12‑month warranty that covers manufacturing defects under normal use. To avoid ordering the wrong part, cross‑check the ENA reference SP433 (also listed as AGSF32WM/SP433 in some catalogs) with your vehicle VIN or use the vehicle lookup tool on the retailer page.

• 12‑month limited warranty included
• Reference numbers: SP433, AGSF32WM for cross‑checking
• Enter your vehicle information on the seller page to confirm compatibility
• Contact seller support for fitment questions before installation

Who is this for: The ENA SP433 iridium spark plug set suits DIY mechanics and professional technicians replacing worn plugs on 3.0L V6 engines in Ford, Mercury, Lincoln or Mazda vehicles.
