Marsram Ignition Coil Pack & Spark Plug Kit UF247 — 4-Coil/4-Double-Iridium for Toyota Corolla 2000–2008, OE-Fit

Marsram's UF247 ignition coil pack and matched double-iridium spark plugs replace worn ignition components to restore reliable starts, smoother idling, and consistent power delivery for compatible Toyota and related models.

If your Corolla, Celica, MR2 Spyder, Matrix or compatible Chevrolet/Pontiac model is showing misfires, rough idle, poor throttle response or reduced fuel efficiency, a fresh set of coils and spark plugs is often the simplest, most cost-effective repair. This Marsram kit combines four high-conductivity ignition coils and four double-iridium spark plugs engineered to meet or exceed original equipment specifications, packaged with an aftermarket one-year warranty for peace of mind.

How will these ignition coils affect starting and idle behavior?

Worn coils can cause weak sparks that lead to hard starts and uneven idling. Marsram's coils use epoxy-sealed housings and copper windings to improve heat resistance and electrical output, helping restore a consistent ignition event across cylinders.

• Epoxy resin outer shell prevents heat damage and cracking.
• High-conductivity copper windings increase ignition speed.
• OE-form fit and electrical characteristics for plug-and-play replacement.

Will double-iridium spark plugs really make a difference in performance?

Double-iridium electrodes deliver a durable, stable spark and resist corrosion that widens gaps over time. These Marsram plugs promote more complete combustion than worn standard plugs, which can translate to improved throttle response and steadier acceleration without engine modifications.

• Double-iridium center and ground electrodes for longevity.
• Reduced electrode wear minimizes gap growth and misfires.
• Engineered center electrode for efficient, consistent combustion.

Are these parts compatible with my vehicle and which OE numbers do they replace?
