GBTAD Ignition Coil Pack and Iridium Spark Plug Kit for Toyota 2.4L — Set of 4, OEM Fit and Improved Spark Reliability

GBTAD Set of 4 Ignition Coil Pack & Iridium Spark Plug UF333 UF494 is a matched replacement kit designed to restore consistent ignition for Toyota 2.4L four-cylinder engines.

This complete kit pairs four high-conductivity ignition coils with four iridium-tipped spark plugs engineered as a matched set to help your engine fire reliably. The components are built to OEM fitment specifications for many Toyota and Scion models from the early 2000s through mid-2010s, so you can expect straightforward installation and compatibility with common part numbers like UF333 and UF494.

Which vehicles will this GBTAD kit fit?

The kit is targeted at 2.4L four-cylinder Toyota and Scion models that use the listed coil and plug part numbers. Always cross-check your vehicle’s year and engine code against the compatibility list before ordering.

• Covers Camry, RAV4, Scion tC and xB, Solara, Highlander with 2.4L L4 engines.
• Fits model years roughly 2001–2015 depending on model—verify exact year fitment.
• Matches common OEM references: UF333, UF494, C1330, GN10313, 5C1299, 9091902266.

How do these coils and iridium plugs improve engine performance?

GBTAD designed the coils with high-conductivity copper windings and dense epoxy sealing to stabilize spark delivery, while the iridium plugs offer a fine electrode for more reliable ignition. Together they address ignition instability issues often caused by worn coils or plugs.

• Stronger, more consistent sparks reduce misfires and rough idles.
• Iridium tips resist wear and help maintain gap integrity over time.
• Coil construction limits electrical leakage and improves heat tolerance.

Will installation be difficult for a DIY mechanic?

Installation is intended to be bolt-on for compatible engines; basic hand tools and a torque wrench are usually all that’s required. If you can remove and reinstall ignition coils and spark plugs, this set is within typical DIY capability, but consult a repair manual for torque specs and gap settings.

• Direct-fit design follows OEM mounting points and electrical connectors.
• Includes four coils and four plugs so you replace the full set at once.
• Recommend using a torque wrench and dielectric grease on coil boots for a secure connection.

What should I expect in terms of durability and support?

GBTAD builds the coils and plugs with attention to materials and sealing to withstand heat cycles and vibration common in modern engines. The product listing includes a quality assurance promise and customer service contact for issues after purchase.

• High-density epoxy and aerospace-grade copper for improved conductivity and protection.
• Iridium electrode resists erosion for longer service life than standard plugs.
• Manufacturer support available for quality concerns or part questions.

Who is this for: This GBTAD four-pack is aimed at owners and independent technicians who need a matched ignition repair kit for 2.4L Toyota and Scion engines—especially when correcting misfires, rough running, or when upgrading worn ignition parts. Choose this set if you want direct-fit replacements that pair coils and iridium plugs for consistent, long-lasting ignition performance without hunting for individual matched components.
