These spark plugs work as described. After installation my fuel consumption reduced on 1.2 L / 100 km.

Failed in Hyundai after one month. Thought just bad luck. Installed second set (checked gap) and failed again after two months with multiple misfires . Bit bullet and bought OEM s. Problem solved.

Ordered this 4-pack of spark plugs to replace the originals on my 2017 Hyundai Elantra GL. Mileage was at 155,000 km and the originals were burnt out. Great build quality, installation was quick and easy. I had to adjust the gap on these new ones to 0.044 mm with my gapping tool but it was straightforward and literally took me 5 mins for all 4 plugs.No more engine misfire, car is running great! Beats paying a dealer/mechanic an arm and a leg for a 25 minute job you can do in your own home.Would definitely recommend.

前回他店ですが4本1000円台という破格で3本のみ使用、交換時期が来て2本購入。送料が…物、性能は悪くないかと？ML21S L385Sなど使えますよ
