OK, so wifes new MAC intake came today and she forced me to put it on NOW. first off damn them for making a filter so Fing difficult to put on. any who it whistles rather loud, whereas her previouse ebay one didnt at all. ive heard of intakes whistling before but how loud do they whistle ive got one on my 98GT and nothing. also has anyone ever figued out why they whistle???? any help is greatly appretiacted and NO there arent any vaccume leaks i checked for em already thought that might have been it. the sound is rather obnoxious.
