Fabtech performance Introduces you an OEM MB 82MM Throttle Body for your M113K Engine offered at less than half of MSRP from the dealer. We do not source used throttle bodies like other companies to save cost and make more profit at the customers expense, nor do we use Porsche or Audi throttle bodies and swap the MB electronics. We only use NEW OEM 82MM throttle bodies in our 82MM T/B Kits. This
