Fit Spark Plug Model?

You can directly use NGKILKAR7B11. Here are the specific details: 1. Spark plug heat range: This refers to an indicator of heat absorption and dissipation capability. The higher the engine speed, the higher the required cooling heat range. The heat range includes numbers from 1 to 9, where 1 to 3 are low heat ranges, 4 to 6 are medium heat ranges, and 7 to 9 are high heat ranges. Most passenger car spark plugs fall within the 5 to 7 range. 2. Spark plug types: There are many types of spark plugs, differentiated by electrodes. Ordinary nickel alloy spark plugs need to be replaced every 30,000 kilometers and are generally installed in cars costing tens of thousands of yuan. There are also platinum, iridium, and platinum-iridium spark plugs, which have a lifespan of 60,000 to 100,000 kilometers due to their rare metal composition.

My 2016 Fit uses NGK DIFR6A11 spark plugs, which are the factory-specified model. However, I should remind you that different model years may require different types. The 2011-2014 models use NGK ZFR6F-11, while post-2018 models switched to DENSO SC16HR11. If you're planning to replace them yourself, remember to either check your vehicle manual or remove the old spark plugs to confirm the model number. Spark plugs significantly impact acceleration and fuel efficiency – I noticed smoother throttle response after my last replacement. It's recommended to inspect them around 40,000 km. If you observe severe electrode erosion, replace them immediately to prevent engine carbon buildup.

Last time I helped a friend replace the spark plugs for a 2014 Fit. The OEM ones were NGK ZFR6F-11. Choosing spark plugs for this car depends on the engine displacement - the 1.5L engine generally uses iridium or platinum plugs. Don't exceed 25 Nm of torque during installation, as over-tightening can crack the ceramic insulator. It's recommended to replace them when the engine is cold to avoid damaging the cylinder head threads. Brand selection is also important - NGK and DENSO have the highest OEM fitment rates, while the common Torch brand found in roadside repair shops can be used as an alternative, but mixing different models is not recommended.

I've been driving a 2017 Honda Fit for over three years, and the original spark plugs are DENSO SC16HR11. During maintenance, I specifically asked the technician, and now the new hybrid version uses the IXEH22TT model, which has an ultra-long lifespan. Replacing them yourself isn't actually difficult; you just need a 16mm spark plug socket and a torque wrench. Be careful not to let dust fall into the cylinder when removing or installing them—you can stuff a clean cloth into the hole. If you notice any oil stains, make sure to check if the valve cover gasket is leaking, and don't just replace the spark plugs and ignore the issue.

Just replaced the spark plugs for our old Fit at home. The 2009 model requires NGK BKR6EIX-11 plugs, and the electrode gap must be maintained at 1.1mm to meet specifications. Don't go for cheap parts when buying replacements - counterfeit products may look similar but have significantly different resistance values, which can lead to poor fuel economy at best or cylinder misfires at worst. The factory manual recommends replacement at 40,000 km, but they can actually last up to 60,000 km provided you maintain the air filter and engine oil on schedule. After replacement, remember to let the engine idle for 10 minutes to allow the ECU to self-learn, and any unstable RPM issues will disappear.
