Marsram Ignition Coil Pack UF596 is a four-piece replacement set engineered to restore reliable spark and smoother engine operation for 1.8L Toyota and compatible models.

When an ignition coil starts to fail you can notice hard starts, misfires, reduced power and poorer fuel economy. This Marsram 4-pack (UF596) is made as a direct-fit replacement for many Toyota, Scion, Lexus, Pontiac and Matrix 1.8L applications from 2008 through 2017. The parts use robust materials and copper windings to deliver consistent electrical transfer at operating temperatures, and they come with a one-year limited warranty for added confidence. Below you’ll find concise answers to common buyer questions about fit, performance, installation and longevity.

Which cars will these coil packs fit?

This four-pack covers a broad range of 1.8L L4 engines across several model years. Always verify compatibility against your VIN or parts finder before purchase.

• Direct fits: 2009–2017 Toyota Corolla 1.8L and 2017 Toyota Corolla iM 1.8L
• Also fits: 2009–2014 Toyota Matrix, 2010–2016 Prius, 2012–2017 Prius V, 2011–2017 Lexus CT200h

How does replacing coils help everyday driving?

Fresh coil packs restore reliable spark delivery so the engine fires consistently. That reduces rough idling, hesitation and engine light triggers — improving drivability without other engine repairs.

• Reduces misfires and uneven running
• Improves throttle response and acceleration
• Can stop intermittent check-engine lights tied to ignition faults
• Helps recover fuel economy lost to ignition issues

What are the design and material highlights?

Marsram builds the exterior from heat-resistant engineering plastic and epoxy resin to resist melting and environmental damage. Internally, high-conductivity copper windings are used to ensure efficient spark transfer and improved longevity under thermal stress.

• Epoxy resin outer layer for heat protection
• High-strength engineering plastic housing for impact resistance
• Copper coil windings for consistent conductivity
• Built to match OEM form factor and electrical connectors

How difficult is installation and what should I expect?

Installation is straightforward for anyone comfortable working under the hood. Coils are bolt-on replacements; basic hand tools and a torque wrench are typically all that’s required. If unfamiliar, a mechanic can swap all four in under an hour on most vehicles.

• Simple bolt-and-connect replacement — no fabrication needed
• Recommended: replace spark plugs when installing new coils
• Check engine codes and erase after installation if relevant
• Professional installation recommended for unfamiliar users

Who is this for: Drivers and DIY mechanics who own compatible 1.8L Toyota, Scion, Lexus or Pontiac Vibe models and want a cost-effective way to address ignition-related drivability issues. It’s also suited to fleet owners and repair shops seeking an economical four-pack replacement with OEM-style fitment and a one-year warranty. Verify fitment with your vehicle’s VIN or the seller parts finder to ensure correct application before ordering.
