If you do an air intake it must use a heat shield otherwise you will probably loose power. I don't know how much a CAI gives you but it sounds nice! Suspension should be done in sets. If you are replacing springs I would match them with the complimentary shocks. Chips may cause a bit more wear and tear since your rev limiter is raised. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org |
