You are right...the same questions get asked time and time again....I think it's time that allot of this stuff gets consolidated into specific categories (i.e. HID, WHEELS, CAI, EXHAUST). I know it would be a pain in the a**. I also think once a thread is dead the MOD's need to go in and remove the comments that really aren't relevant to what is being asked.
And I did a search of "HID INSTALL" and your 3 links are not the same 3 links I got...I got one for Subwoofer install, one for a 3m Mask kit for sale and yes one for HID install....just saying. Maybe I do my search different. I just hit search, type in what I am looking for, and then search...If there is a better way please let me know because I get just as frustrated hitting search as I do just asking the quesion and hoping someone with some knowledge is nice enough to give me a little info, rather than scold me like I am some 12 year old.....
