Perfect upgrade to my tuned elantra n
Switched to these HKS spark plugs and wow — my car runs smoother and feels more responsive. Easy to install and they hold up great even when I push the engine hard. Definitely a solid upgrade if you want better performance without breaking the bank. Highly recommend!

High powered turbo spark plug
Great high horsepower plug. Works in the bi turbo M157 motor with a tune. Keeps things cooler and happy. More durable than oem when tuned.

Authentic
I was skeptical about this but then asked the seller if this is a Genuine product he answered yes. Once the product arrived and tested I realize that it is 100% authentic. Worked great on my Veloster Turbo

Already bought it again :)
I already bought this item for 2nd time. It gave me the performance I needed as I have my car tuned and needs higher performance spark plugs. It lasted for more than 50k kilometer
