Tucson Engine Performance Increase?
I just bought a 2017 Tucson SE with the 2.0 four cylinder GDI engine, 6 speed auto/Shiftronic. I know it's not a performance engine, but was wondering what simple additions/changes could be made to increase engine performance/HP? I do not want a Cat-Back performance exhaust system. Is there anything else that would increase performance and still pass smog tests in CA, USA?
