Parts for your 2014 Honda Cr-v-Spark plugs

2014 Honda CR‑V spark plugs

Spark plugs are absolutely relevant for the 2014 Honda CR‑V petrol models. Honda’s 2014 CR‑V Owner’s Manual and service literature specify iridium spark plugs for the 2.0‑litre and 2.4‑litre i‑VTEC engines, and major plug catalogues from NGK and Denso list OEM‑equivalent iridium part numbers for these engines. Only the 2.2 i‑DTEC diesel variant skips spark plugs altogether, as diesels use glow plugs for heating rather than spark for ignition.

On the petrol CR‑V, the plugs live at the heart of the ignition system, firing thousands of times per minute to light the air–fuel mix. Good plugs help the engine start cleanly on cold mornings, idle smoothly at the lights, pull strongly up motorway on‑ramps, and sip less fuel. The 2014 CR‑V uses a coil‑on‑plug setup with one plug per cylinder, so keeping all four in top nick makes a noticeable difference.

For servicing, Honda schedules long‑life iridium plugs, typically around the 100,000 km mark (or about 5–6 years), though checking them sooner is smart if the vehicle sees lots of short trips, dusty roads, heavy towing, or runs on lower‑quality fuel. Even when iridium tips last, the seals, threads and insulators still deserve periodic inspection to prevent misfires and hard starts.

• Use OE‑grade iridium plugs (e.g., NGK ILZKR7B‑11S or the Denso equivalent) with the correct heat range.
• Replace the full set at once and inspect coil boots, a dab of dielectric grease helps future removal.
• Iridium plugs are pre‑gapped, avoid bending the fine tip. The factory gap is around 1.0–1.1 mm—verify with a gauge rather than adjusting.
• Install on a cool engine and tighten to Honda’s service‑manual torque. Modern plated threads generally don’t need anti‑seize, if it’s used, adjust torque accordingly.
• If plugs are fouled, fix the cause as well—think air filter, PCV, injector spray pattern, or oil consumption.

Tell‑tales of tired plugs include a rough idle, sluggish take‑off, poorer fuel economy, harder cold starts, and a flashing check‑engine lamp under load. Fresh, correct plugs restore that easygoing CR‑V character and keep emissions in check.

Driving a 2014 CR‑V diesel? Different story—your i‑DTEC uses glow plugs, not spark plugs, so this advice applies to petrol variants only, as confirmed by Honda’s technical documentation.

Popular questions about 2014 Honda CR‑V spark plugs

How often should spark plugs be replaced on a 2014 Honda CR‑V?
For the petrol engines with iridium plugs, plan on about 100,000 km or 5–6 years under normal Aussie and Kiwi conditions, as outlined in Honda’s service schedule. If you do frequent short trips, tow, or drive in dusty areas, ask your technician to inspect them earlier.

What plug type and gap does the 2014 CR‑V use?
Use OEM‑equivalent iridium plugs such as NGK ILZKR7B‑11S or the Denso counterpart. They come pre‑gapped around 1.0–1.1 mm. Iridium fine‑wire tips are delicate—verify the gap, but don’t force adjustments.

Do diesel 2014 CR‑V models have spark plugs?
No. The 2.2 i‑DTEC diesel uses glow plugs to aid cold starting. Spark plugs apply to the 2.0 and 2.4 petrol variants only.
