Gedlex Ignition Coil & Iridium Spark Plug Kit UF247 Pack of 4 for 1.8L L4 — OEM Fit, High-Energy

Gedlex UF247 ignition coil pack with iridium spark plugs is a plug-and-play replacement set engineered to restore reliable spark, reduce misfires, and match OEM fit for 1.8L L4 engines in select Toyota, Chevy and Pontiac models.

This kit combines four UF247 ignition coils and compatible iridium spark plugs sized for 1.8L four-cylinder engines found in many Toyota (Corolla, Matrix, Celica, MR2 Spyder) and partner-platform vehicles (Chevrolet Prizm, Pontiac Vibe) from model years 2000–2008. Each component is built to meet or exceed common OE specifications, offering a straightforward swap for worn or failing coils and plugs. The set emphasizes heat and corrosion resistance, improved ignition energy, and a straightforward installation that keeps your engine running smoothly without elaborate tuning.

• 2000–2005 Toyota Celica GT 1.8L L4
• 2000–2008 Toyota Corolla 1.8L L4
• 2003–2008 Toyota Matrix 1.8L L4
• 2000–2005 Toyota MR2 Spyder 1.8L L4
• 2000–2002 Chevrolet Prizm 1.8L L4
• 2003–2008 Pontiac Vibe 1.8L L4

How will replacing coils and plugs with this set affect engine performance?

Replacing aged coils and worn spark plugs typically restores consistent ignition energy and improves combustion stability. That can reduce misfires, smooth idle, and help recover lost throttle response without aftermarket tuning.

• Higher energy output for a stronger, more stable spark
• Iridium plugs provide precise ignition and longer service life
• Reduced rough-idle and fewer misfire codes under typical conditions

Are these Gedlex parts easy to install and compatible with OEM systems?

Yes — the coils and plugs are designed for direct replacement and follow original equipment dimensions and electrical interfaces. Installation typically requires basic hand tools and about the same time as other standard coil-swap jobs.

• Plug-and-play connectors match factory harnesses
• No ECM reprogramming required for stock vehicles
• Meets or exceeds common OE spec numbers (UF247, C1249, IC372, etc.)

What build quality and durability features are included?

Gedlex combines improved module materials and corrosion-resistant finishes to extend service life under typical driving conditions. The design focuses on heat tolerance and wear resistance to withstand repeated thermal cycling in the engine bay.

• High-quality ignition modules for improved heat resistance
• Corrosion-resistant casing and terminals for longevity
• Iridium spark plugs for enhanced electrode wear life

Who is this for: The Gedlex UF247 ignition coil pack and iridium spark plug pack of four is intended for owners and mechanics servicing 1.8L L4 Toyota Corolla, Matrix, Celica, MR2 Spyder, Chevrolet Prizm, and Pontiac Vibe models within the listed years. It suits drivers needing a direct OEM-style replacement to correct misfires, restore throttle responsiveness, or perform scheduled ignition maintenance without aftermarket calibration. If you have a compatible vehicle and are seeking a cost-effective, durable replacement set that aligns with OE part numbers, this kit is a practical choice.
