I am about to purchase some. I have done some research and they seem to be great. I have not read one bad thing from these plugs. They even claim some horsepower and mileage improvements (not sure if true). But at $11 a plug . They may be a but pricey for most. I would reccomend if your boosted. Thats just my opinion.
