Hey I am new to this. I bought a 2007 CX7, so far I like it. I sold my 2004 lightning(430 hp ) Before that I had a Bullitt mustang(320 hp).The reasonthe fords are gone is because I am now staioned in Wiconsin, and they do not like the snow.I miss the horse power, but the handling of the mazda is so much better. I want a little bit more kick out of the mazda just to show that she is not no grocery getter. I am not to familar with the Japanese part brands, so any help would be great. I am looking at cold air intakes, but there does not seem to be alot out there.(I could be looking at the wrong web sites also). I am looking at some computer mods too. The trans seems like it could use some help. Any help you guys/ gals could give me would be great. Thank you for your help.
