K-Tuned aluminium DBW 72mm throttle body (Civic 07-12/S2000 06-09)
90% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives. So keep a close eye on your mailbox.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance). We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product'' below in the product description.
Our 72mm Drive By Wire Throttle Body is direct bolt on to RBC/RRC manifolds and others with the same bolt pattern. It is a true 72mm bore which is larger than ZDX throttle at the butterfly. This throttle body requires some form of engine management (Flashpro or Ktuner) to properly manage the increased airflow. We used the stock configuration and design using an OEM connector to avoid jumper harness. This gives it an almost OEM look when installed. Inside you will see the machined 72mm bore and brass butterfly. There are two 1/8NPT vacuum ports on the bottom which can be used for evap, brake booster, or vacuum reference. Included you will get a thermal gasket, mounting bolts, and two 1/8NPT plugs.
The inlet will use a 3" silicone coupler. You may need to change the coupler to match your intake.
How big is 72mm TB? We did some measurements and compared it to other stock and common options. We measured the area at the smallest opening since this would be the bottle neck in the system.Â
