NGK SILZNAR8C7H Laser Iridium Spark Plug
This NGK Laser Iridium spark plug is built for modern turbocharged, direct-injection petrol engines. It offers strong ignition under high cylinder pressure, stable idle, and reliable performance at sustained motorway speeds. The fine iridium centre electrode needs less voltage to spark, which helps cold starts and keeps misfires down. A platinum-tipped ground electrode improves wear life, so performance stays consistent over more miles.
Use this plug as specified by the vehicle manufacturer or trusted tuning guidance. It suits many high-output petrol engines that call for an NGK heat range 8 plug and a resistor type. Always confirm fitment with the vehicle lookup or the Vehicle Fitment tab.

Great pair of Jean and great price!
Size: 14, Color: Washed Blue, Size: 14, Color: Washed Blue
I can’t believe these were only $13. They feel and look like quality jeans, very basic/simple boot cut. My daughter says they’re stretchy and comfortable. I ordered her a size 14 (12’s fit her waist but are always too short) She’s 11 years old, 5’ tall, about 80lbs. The waist adjusters were great for the perfect fit.

Amazing jeans! My daughter loves them!
Size: 7 Slim, Color: Washed Blue, Size: 7 Slim, Color: Washed Blue
My daughter is really slim but tall. She is 7 about 50 pounds. She loves them and I’m so happy because all the other jeans that I buy I have to return cuz they are all too big on her. The jeans are stretchy and feel much more expensive for the price! Great quality! I will be ordering more for sure!
