TL;DR Champion 9407 (RER8ZWYCB4) is an aftermarket iridium plug for 2006-2022 Honda Civic and CR-V; OEM cross-references align to Honda R-series engine families. No manufacturer service interval stated.
Iridium center electrode, platinum ground electrode, V-trimmed geometry, M14x1.25 thread. Champion is an aftermarket cross-reference supplier; NGK and Denso are Honda's OE suppliers for these applications. OEM part numbers (12290-R40-A01, R40-A02, R48H01) confirm Honda R-series fitment alignment, and community reviews report correct install without heat-range or reach complaints. Heat range number and service interval are not disclosed on the product page.
Right pick for a 2006-2022 Honda Civic or CR-V owner needing a plug that fits at a lower cost than the OE-supplier part. Skip if OE provenance is the priority; the NGK plug specified for your Honda application provides that.
No chemical exposure pathway: ceramic-and-steel ignition part, no SDS. Iridium and platinum electrode tips carry small precious-metal mass; steel shell is recyclable as ferrous scrap, alumina-ceramic insulator landfills. No Champion take-back program as of 2026.
The Champion 9407 (RER8ZWYCB4) is listed by the manufacturer for 2006-2022 Honda Civic and Honda CR-V. OEM cross-reference part numbers confirmed in the Amazon product specification include Honda 12290-R40-A01, R40-A02, and R48H01, which are Honda R-series engine applications. Always verify against your vehicle's OEM service manual before installation.
Champion positions the 9407 as an aftermarket cross-reference for the Honda R-series applications listed. NGK and Denso are Honda's primary OEM suppliers for spark-ignition engines. Champion is an established aftermarket manufacturer and the OEM cross-reference part numbers align with Honda R-series fitment, but it is not the OE-supplied plug for these applications.
Champion does not state a specific service interval on the product page or in the feature bullets for the 9407. 'Delivers maximum life' is marketing language, not a mileage rating, and no manufacturer-stated interval has been located. Consult your Honda service manual for the OEM-recommended spark plug change interval for your specific engine.
Yes. This 4-pack (ASIN B00HFLA48K) is an Amazon add-on item and requires a qualifying order minimum or a Subscribe & Save subscription to purchase standalone. The single-plug ASIN (B0076GI5MQ) is also an add-on item.
Champion does not disclose a factory gap specification on the product page. Gap verification with a feeler gauge before installation is advisable.
