Marsram ignition coil pack UF333 4-coil set for Toyota Camry 2.4L Japan-built — copper windings, heat-resistant housing

Marsram Ignition Coil UF333 is a direct-replacement ignition coil pack engineered to restore reliable spark and smooth running on compatible Toyota, Scion, Lexus and Pontiac 2.0–2.4L engines built in Japan.

This ignition coil pack set (4 coils) is designed as a bolt-in replacement for vehicles that use the UF333 family of coils. It pairs high-conductivity copper windings with a heat-resistant epoxy and engineering-plastic housing to resist engine-bay heat and deliver consistent ignition performance. Before ordering, verify your vehicle’s country of manufacture—this coil fits Japan-built models (VIN starts with "J") and will not fit U.S.-built VINs that begin with a number.

Which vehicles will this UF333 coil pack fit?

This coil is compatible with many Toyota, Scion, Lexus and Pontiac models that used Japan-manufactured 2.0–2.4L engines. Fitment covers selected years of Camry, Corolla, Highlander, RAV4, Matrix, Solara, Scion tC/xB, Lexus HS250h and Pontiac Vibe. Always confirm year, engine size and VIN origin before purchasing.

• Common Toyota fits: Camry (2002–2005, 2007–2011) 2.4L Japan-built examples and selected Corolla, RAV4, Highlander, Solara and Matrix models.
• Other makes: Scion tC/xB, Lexus HS250h and Pontiac Vibe where the factory coil is UF333 family.
• Use the listed OEM replacement numbers (UF333, UF494, 90919-19023, etc.) to cross-check compatibility.

How does Marsram UF333 improve ignition reliability?

The UF333 replacement uses high-conductivity copper windings for faster and more consistent spark delivery while the external shell is epoxy-coated and molded from heat-resistant engineering plastic. This construction reduces the chance of coil overheating, cracking or internal shorting that can cause misfires or rough idle.

• Copper coil cores for efficient electrical transfer and stable spark.
• Epoxy resin exterior and reinforced plastic housing for better heat tolerance.
• Packed as a 4-coil set to replace multiple cylinders at once and ensure matched performance.

What installation and warranty details should I know?

Installation is straightforward for experienced DIYers or mechanics—unplug the electrical connector, remove the mounting bolt, extract the old coil and install the new unit. The product ships as a set of four coils and includes a one-year warranty against manufacturing defects; contact Marsram customer support promptly if an issue arises.

• Ships as a 4-coil pack for multi-cylinder replacement convenience.
• One-year warranty covering defects; contact Marsram for warranty support.
• Refer to OEM part-number cross-references to confirm fit before removal.

Are there any cautions I should follow before buying?

Yes—this coil specifically fits vehicles assembled in Japan. The VIN check is essential: Japanese-built cars have VINs that start with the letter "J"; U.S.-built vehicles start with a number and are not compatible. Also verify engine displacement and model year against the listed applications.

• Verify VIN origin (must start with "J") prior to purchase.
• Confirm engine size (2.0L / 2.4L as applicable) and model year fitment.
• Use OEM and alternate part numbers provided to double-check compatibility.

Who this is for: The Marsram UF333 coil pack is intended for owners and technicians who need a dependable, cost-effective replacement for worn or failing ignition coils on Japan-built Toyota, Scion, Lexus or Pontiac 2.0–2.4L models. It suits DIY mechanics replacing multiple coils at once, independent shops seeking a reliable aftermarket option, and anyone who confirmed VIN and part-number compatibility and wants heat-resistant construction with a one-year warranty.
