“My 2017 Gen 2 Hyundai i20 1.4 petrol Auto came with NGK SILKR6C10E (97098)spark plugs as standard, so I chose NGK as replacements, though I actually got a new set as spares, as they have been very reliable and I don't go by Hyundai's recommendation to replace the spark plugs at 100,000 miles as my car is actually already on it's second set of spark plaugs having fitted them at 40,000 miles. The car has currently done over 57,600+ miles to date.”
