I just bought 4 Bosch Plat 4 plugs and my 91 car hates it. I bought them in 8/20/03 and noticed a slight change but now after 5 weeks it is rough again so I went back to NGK-R plugs. Yes I did change my wires when I bought the Plat 4s so I know it isn't the wires. So I am selling all 4 plugs for 13.00 and that includes s/h. I can you a picture of the plugs and the receipt to verify that I bought them
