Marsram Ignition Coil Pack with 4 Double‑Iridium Spark Plugs for 2009–2017 Toyota Corolla 1.8L L4 — Direct Fit, OE‑Style Reliabili

Marsram ignition coil pack UF596 with matching iridium spark plugs replaces OEM coils and plugs to restore reliable spark and consistent combustion for 2009–2017 Toyota Corolla 1.8L L4 and compatible models.

If your Corolla, Prius, Matrix, or related model is showing rough idle, misfires, or reduced throttle response, worn coils or spark plugs are a common cause. This Marsram kit supplies four ignition coils and four double‑iridium spark plugs engineered to meet or exceed original equipment specifications. The coils use heat‑resistant housings and high‑conductivity copper windings, while the plugs feature a durable double‑iridium electrode that resists corrosion and maintains a stable gap for longer life.

Will these coils and plugs fit my car?

These parts are specifically selected to replace OE units on a range of 1.8L L4 Toyota and Scion models plus some Lexus/Pontiac variants. Always verify fit using your vehicle year, engine size, and the seller’s fitment checker before ordering.
