A-Premium Ignition Coil Pack Set for Honda Civic 1.8L (2006–2011) — 4-Pack 3-Pin Direct-Fit, OE-Style

A-Premium set of four 3-pin ignition coils replaces worn units on Honda Civic 2006–2011 I4 1.8L engines for reliable spark delivery and restored engine smoothness.

If your Civic is showing rough idling, reduced fuel economy, misfires, or a check-engine light tied to ignition faults, these direct-fit coil packs are built to be a straightforward OE-style replacement. Designed to match factory dimensions and electrical connections, the set helps reestablish consistent spark timing without the need for modification. Each coil is new, pre-tested, and accepts the same mounting points and connector interface as the original part numbers 30520-RNA-A01, 30520RNAA01, and UF-582.

How will these coils affect engine performance?

Replacing degraded ignition coils restores the spark energy reaching each cylinder, which typically yields smoother idling, fewer misfires, and steadier throttle response. You may also notice improved fuel efficiency if weak sparks were causing incomplete combustion.

• Consistent high-voltage output for reliable combustion
• Reduces misfires that trigger diagnostic trouble codes
• Helps return engine to factory-like responsiveness

Are these coil packs compatible with my vehicle?

These coils are manufactured to directly replace OE units on Honda Civic sedans and coupes with the 1.8L I4 engine from 2006 through 2011. Confirm fitment by checking your vehicle details and the reference numbers provided.
