It won't void any part of your warranty unless the dealership can prove that the problem was caused by those parts or the installation of those parts. Your only worry with I/H/E would be hydrolock, and that's not going to happen with an Icebox unless you drive into a lake.

 

there is no correlation between aftermarket parts and warranty....well, depends on the level of mods.....

lst year i brought my car to the dealer to get my head gasket and my oil pan gasket to be changed under my extended warranty.....

yes, i drove into the dealer, pink car and all....with all the mods and told them to fix the leaking oil for free.....
