I have heard mixed opinions and views on this one...
View 1:
magnusson moss act - an aftermarket part cannot void warranty.
View 2:
Even chipping your car or adding a cold air intake / minor mods can void your warranty.
Has anyone had any struggles with their respective car companies by adding mods to their cars? Looking to chip my car / add cold air and some other minor stuff.... Added extended warranty though (only because ford), so dont want to screw with that.
