Just a brand nae

I'm very disappointed with this product. I installed the full set on my 2004 Toyota Prius, and after only two weeks of normal driving, one of the spark plugs completely failed. It caused engine misfires, flashing check engine light, rough idle, and the car barely ran. I had to remove the plug and found it was already damaged/defective. I expected better quality, especially from this brand. Now I have to spend more money and time fixing the issue. I do not recommend this product based on my experience. Pros: None Cons: Failed after 2 weeks, caused misfire, wasted time and money
