Marsram UF333 Ignition Coil Pack and Iridium Spark Plug Set for Toyota 2.4L (2007–2011 Camry) — 4-Coil, Double Iridium

Marsram UF333 ignition coil pack and iridium spark plug set replaces worn ignition components to restore reliable starts and steady power for compatible 2.4L Toyota and select Lexus/Scion/Pontiac models.

This comprehensive aftermarket kit pairs four high-conductivity ignition coils with four double-iridium spark plugs engineered for consistent firing, improved combustion stability, and long life. Designed to meet or exceed original equipment specifications, the set fits a wide range of Toyota 2.4L engines (including many Camry, RAV4, Matrix, Solara and Highlander years) and select Lexus, Scion and Pontiac applications. Each coil uses durable epoxy and reinforced engineering plastic to resist heat and vibration, while the spark plugs incorporate a corrosion-resistant double iridium electrode to reduce gap growth and enhance ignition reliability.

Will these coils and plugs fit my Toyota Camry 2007–2011 2.4L?

If your vehicle uses the UF333-style coil pack and the specified 2.4L L4 engine, this Marsram set is a direct-fit replacement in many model years listed. Always verify compatibility by checking your VIN and the fitment or part-number reference before purchase.

• Direct applications include 2007–2011 Camry 2.4L (including Hybrid and CE/Base trims where specified).
• Also fits numerous 2001–2010 Toyota models with the 2.4L L4 engine and selected Lexus/Scion/Pontiac 2.4L variants.
• Replaces OEM part numbers such as UF333, UF494 and other listed equivalents—confirm with the vehicle fit tool.

How do these parts improve engine performance and reliability?

The coils use high-conductivity copper windings and heat-resistant epoxy housing to deliver stable, powerful sparks under load, while the double-iridium plugs maintain a consistent gap and resist corrosion. Together they promote more complete combustion cycles, smoother idle, and dependable ignition under cold starts or heavy throttle.

• Epoxy resin and engineering plastic housings protect coils from engine heat and deformation.
• High-conductivity copper cores increase ignition speed and spark consistency.
• Double iridium electrodes limit gap erosion for longer service intervals and consistent firing.

What comes in the package and is installation difficult?

The kit ships with four ignition coils and four iridium spark plugs backed by Marsram’s one-year aftermarket warranty. Parts are manufactured to OE-style dimensions so most installations are straightforward for experienced DIYers or mechanics, requiring only standard hand tools and basic ignition service steps.

• Includes 4 coil packs and 4 double-iridium spark plugs plus warranty support.
• OE-form fitment minimizes the need for modifications; follow torque specs and gap checks.
• If unsure, a professional installation is recommended to verify connector seating and torque accuracy.

How durable is this aftermarket kit and what warranty applies?

Marsram builds the coils with reinforced plastic and epoxy to reduce heat-related failure, and the plugs use corrosion-resistant electrodes to slow degradation. The set carries a one-year worry-free aftermarket warranty; contact Marsram support promptly if you experience any defects or fitment concerns.

• Coils are constructed to resist overheating, vibration, and electrical wear.
