Many racers like doing things themselves. However, if you don’t have a welder or don’t feel comfortable enough to weld your own manifold, we’re here to help! For our customers like this we offer a bung installation service. First you send in your manifold or order a new one through us. Next, tell us what kind of bungs you need and where on the runner they will work best for you. We will then drill your manifold, weld in bungs, and then blend it back to the port. We offer this service for annular nozzle, 90° nozzle and water bungs. EFI bungs can be done at an additional cost!
