Review on 🔌 NGK ILKR8E6 Spark Plug 1422 - Pack of 4 by Jesse Blair

I have a 2012 Kia Optima Tgdi with 63k with OEM spark plugs. After reviewing many brands and a thermal range I settled on this one and received a 28th Lord clearance. It's like having another car, one on the ground with ECO on, the car rips through the tires and the TC blinks 2 or 3 times, but when ECO is off the TC interrupts the fun. You'll notice a drop in gas flow and a little roughness at idle in the cold, but only for a few seconds. You need these plugs. My only mod is a K&N filter with a short frame and that's it. I have read that these plugs are prone to breakage but do some research and you will see that they are for people who put plugs too far or too tight. I'm 28 and haven't looked back in about 2 weeks and had many big smiles on my face. The cheapest song!
