Inline Four Throttle Body Service

Inline Four offers you the service of overboring your factory throttle body. We will bore out your throttle body to its maximum limit and also taper it to create a venturi effect. Our throttle bodies are also equipped with a shiny new polished brass throttle plate...only the best in materials! We can bore your Type-R throttle body to a 70mm and taper it to a 66mm end. We have many of these already in stock, so turn around time is usually within 1-2 days. We require a core exchange and will inspect your core upon receipt to ensure that it is in good condition. For details, please call us at 714-903-1898 to schedule an order for one of our throttle bodies service.
