i just got my is300 a wk ago, ive been thinking hard about what to do. I guess in generaly i'll go get a custom turbo instal or turbo kit for my car. but for now i need somethin to basically kill time(possibly 2-3 yrs). i was wondering if an intake and/or an axle back exhaust would void the warranty. im leaning towards to just getting an intake for now. any suggestions?
