These are interchangeable inlets for K-Tuned Throttle Bodies. You can easily switch the standard barb fitting to a 3.5' or 4' V-Band or Vanjen fitting. No more welding your throttle bodies! Just remove the 4 bolts holding the standard inlet and replace it with your chosen new inlet. You can reuse the o-ring that came with your throttle body. It's suitable for OLD STYLE K-Tuned 90mm Throttle Bodies including Domestic KTD-TB9-90D, K-Series KTD-TB9-IAK, and B-Series KTD-TB9-IAB. If you're not sure which throttle body you have, email

Using these K-Tuned throttle body inlets is easy. First, if you want to change the fitting, locate the 4 bolts that hold the standard inlet. Remove these bolts carefully. Then, take your new inlet of choice - whether it's a 3.5' or 4' V-Band or Vanjen fitting - and place it in the position of the old one. Remember to reuse the o - ring that came with your throttle body. This will help ensure a good seal. As for maintenance, keep an eye on the o - ring for any signs of wear or damage. If it looks worn out, it's a good idea to replace it. Also, make sure the bolts are tightened properly after each replacement. If you're ever unsure which throttle body you have, don't worry! Just send an email to info@k - tuned.com with a picture of your throttle body, and they'll help you out.
