In 1997, the CR-V hit the market as one of the first compact crossover SUVs. Its large cargo area, four-cylinder engine and car underpinnings allowed it to haul like an SUV, while it handled and got gas mileage similar to a car. The 2009 CR-V came with a 2.4-liter engine and a Maintenance Minder system that displayed "A 4" or "B 4" in the odometer screen when it was time to replace the spark plugs.
Honda recommends NGK IZFR6K-11 or Denso SKJ20DR-M11 spark plugs in the 2009 CR-V, but you can opt for an equivalent set of plugs from a different manufacturer. The CR-V requires a spark plug gap of 0.044 inch. This gap is not adjustable, so exchange and incorrectly gapped plugs for new ones. The spark plugs in the CR-V require 13 foot-pounds of torque.
