coil upgrade options???

[dolphaxel]

So I'm thinking some new fancy coils would do me some good and starting to look at options. I have a 03 m800 sie and want to know what people would recommend. The only thing I seem to find readily available are the exact fit brand. They look good but it's a coil so they all look the same minus the color. Not looking for anything nutso, just a good high quality replacement for everyday riding. For what it's worth I have aftermarket pipes, PC3, and a high flow air set up. Thanks in advance.
