Does installing an Air Doc Intake require any permanent modification to my vehicle that should be a concern at the end of a lease or trade in?
No. (The only permanent modification with the H367 system for 2005/07 models is drilling one 1/8″ hole in the plastic flange of the air filter box where the new Air Doc inlet snorkel is anchored by a single #6 screw. When the screw is removed, and the stock snorkel is re-installed this hole is not easily visible, and has no impact on the function of the stock system.) The H308, H3A, H2, and GM02 models require absolutely no irreversible modifications.
