Marsram Ignition Coil Pack UF311 for Honda 2.4L L4 (4-Pack) — Direct-Fit, Copper Windings

Marsram Ignition Coil Pack UF311 is a direct-fit four-coil replacement engineered to restore reliable spark for 2.4L L4 Honda applications including 2003–2007 CR‑V and Accord models.

This four-pack of Marsram ignition coils is built as an aftermarket alternative to OEM coil packs used on a range of Honda and Acura 2.0–2.4L inline‑4 engines. Each coil uses a high-conductivity copper winding and a durable epoxy-resin outer shell combined with reinforced engineering plastic to resist heat and vibration. The assembly replaces multiple factory part numbers (UF311, UF583, 30520PNA007, and others) so it’s suitable for customers who need a complete cylinder bank refresh rather than individual coil swaps.

Will this coil pack fit my vehicle?

Compatibility covers several Honda and Acura models with 2.0L and 2.4L inline-four engines. Verify your exact model year and engine code against the listed part numbers and the vehicle-fit tool before ordering to ensure a correct match.

• Common fits: 2003–2007 Honda CR‑V 2.4L, 2003–2006 Honda Accord 2.4L
• Also compatible with select Acura RSX, Honda Civic Si, Element, and S2000 applications
• Replaces OEM numbers: UF311, UF583, 30520PNA007, 30520RRA007, 30520PMA007, and equivalents
• Check the vehicle-fit confirmation (seller fit tool) prior to purchase

How is Marsram's design built to last under engine heat?

The coils combine an epoxy resin encapsulation with high-strength engineering plastics to resist melting and degradation when temperatures rise. Internally, copper conductor windings improve electrical throughput and spark responsiveness compared with lower-grade wire.

• Epoxy-resin exterior protects against heat and contaminants
• Reinforced plastic housing resists vibration and cracking
• Copper windings for better conductivity and stable spark energy
• Manufactured to meet or exceed original equipment design

How easy is installation and what’s included in the package?

Installation follows the same steps as the original coils, so a basic tool set and standard mechanical knowledge will let most DIYers complete the swap. The package contains four coils—enough for a full bank replacement on inline‑4 engines—reducing troubleshooting time from mismatched old and new coils.

• Package contents: 4 ignition coils (full cylinder bank replacement)
• Direct-fit design mirrors OE mounting points and electrical connectors
• Simple bolt and connector swap; no special programming required
• Recommended torque and connector checks during installation

What warranty and support does Marsram provide?

These coils are backed by a one-year limited warranty and customer support from Marsram. If any product issues arise, the seller requests contact so they can respond promptly and resolve faults within the warranty period.

• 1-year limited warranty included
• Seller support for installation or compatibility questions
• Quality testing and manufacturing traceability claimed by brand

Who is this for: The Marsram UF311 four-pack is aimed at owners and independent mechanics who want a complete, cost-effective replacement for a failing ignition bank on Honda and compatible Acura 2.0–2.4L inline‑4 engines. It’s especially useful if you’re experiencing misfires, rough idle, or erratic spark across multiple cylinders and prefer replacing all coils at once for consistent performance and simplified troubleshooting. Confirm vehicle fit with your model year and OEM part numbers before purchase to ensure a smooth installation.
