The 2008 Honda CR-V has four spark plugs—one for each cylinder of its 2.4-liter four-cylinder engine.
Engine overview
The 2008 CR-V uses a 2.4-liter inline-four engine (part of Honda's K24 family). This engine employs a coil-on-plug ignition system, with a dedicated spark plug for each cylinder, totaling four plugs.
Where the plugs are located and how they are wired
Each spark plug sits in the cylinder head and is paired with its own ignition coil in a coil-on-plug arrangement. The four coils sit above the engine, aligning with the four spark plugs. Access from the top is generally straightforward when performing maintenance, though some components may require removing engine covers or air intake parts.
Choosing replacement plugs
Recommended types and gaps
Honda models from this era commonly use iridium or platinum spark plugs for longevity, with NGK or Denso as popular OEM-compatible suppliers. The gap specification is typically around 0.043 inches (1.1 mm) for many 2.4L Hondas, but always verify with the owner's manual or a service bulletin for your exact VIN. If you install copper plugs, you may need to gap and expect shorter life.
Maintenance considerations
As with most Hondas, the spark plugs on a 2008 CR-V are designed for long intervals under normal driving. Expect a replacement interval in the 105,000-mile range for iridium/platinum plugs, but driving style and conditions can shorten or extend this. Always follow Honda's maintenance schedule and use the proper torque when reinstalling to avoid thread damage.
Bottom line
In short: four spark plugs in a 2008 Honda CR-V, one for each cylinder of the 2.4-liter engine, with four corresponding ignition coils in a coil-on-plug setup.
Summary
The 2008 Honda CR-V uses four spark plugs—one per cylinder. They reside in the cylinder head under coil-on-plug ignition coils, and replacement follows typical long-life plug guidance with OEM options from NGK or Denso. Always consult the owner's manual for exact part numbers, gaps, and maintenance intervals for your vehicle's VIN.
