Drill & Tap Kits

GlowShift’s Drill & Tap Kits are made for anyone looking to drill and tap directly into their vehicle’s exhaust manifold or intake manifold. These Drill and Tap Kits are available when you need the right drill bit and tap size, without having to buy an entire set of both. With our kits, you buy what you need, and only what you need, also ensuring that you’re getting the correct drill and tap together for the job. Two different sized drill tap kits are available in either 1/8-27 NPT or 3/8-18 NPT.
