Important to know
This T143 Long Block Engine requires a T143-specific or custom exhaust system, which must be purchased separately. Carburetor/intake and ignition system are also not included and must be acquired separately. Revised oil routing on '99-'06 Touring models makes an oil line installation kit unnecessary.
