I'm also a Satria owner...currently using Mivec rs nose cut...never had problem with the Police...for me just use the part if u want to...try to avoid the road where JPJ always used for ops... :)
my evo 7 fan didnt work fast and cause the water tempreture up,it work fast in the beginning but after sometimes,it slow down.Is horrible when i facing traffic jam at KL,need to restart the car to let the fan work...
