NGK Laser Iridium spark plugs for 10th Gen Honda Civic Si 1.5T models are a direct factory replacement for the stock plugs. In fact, they are the stock plugs. These are very high quality plugs that will work well in the Honda Civic 1.5T engine. They come gapped appropriately for a stock engine from NGK but you can regap them based on your needs if you are producing more power and boost than stock. Each plug is sold individually, order a quantity of 4 for a full set.
*This plug is specific for the Si models. The non-Si models have a slightly different version with a different gap from NGK and are available separately.
