      Video Review & Installation

      Ryan: This BBK 78-millimeter Throttle Body is for those of you that have a 2012 to 2018 JK with that 3.6-liter engine that are looking for ways to squeeze in a little bit more power out of that motor. This is going to be a fairly easy two out of three wrenches for the installation, a little bit of disassembly and reassembly to do in order to get this installed, and we're gonna show you how to do that in just a second.So, if you are looking for a little bit more power from your Jeep, this is going to be one way to do that. If you've added big tires to your Jeep, I would recommend re-gearing the Jeep first. That's going to be the most important thing you can do to get that power feeling back into your Wrangler if it's feeling underpowered because you have big tires. But if you've have re-geared, if you've recalibrated, if you've done everything else there is to do and you still wanna squeeze a little bit more power out, something like this is going to help, this is going to help to get more air into the engine, which is, in turn, going to give you more power. The nice thing about this is that it does not require a tune or any other major modifications to the Jeep. You just bolt this on and have a little bit better throttle response, and a little bit more power coming from underneath the hood. Now, this is one of those pieces that is an intricate piece. It's electronics. It's moving pieces. It's very important to the running of the engine. So this isn't going to be an inexpensive modification, this is going to come in and right around that $450 mark. As I said before, if your Jeep's feeling sluggish, because you've added big tires and you haven't re-geared yet, I would take that $450 and put it toward re-gearing. If you've already done all those other things and you still want a little bit more power, that's when I would start taking a look at a piece like this. Like I said before, two out of three wrenches for the installation, let's show you how to do it.Man: Tools required for this install: a 0.25-inch drive, extension, 8-millimeter socket, 10-millimeter socket. Start by removing your engine cover. We're gonna start first by removing this intake tube using a 10-millimeter socket on the mounting hardware. And then an 8-millimeter on the clamps. There's another clamp over here by the throttle body. Remove your overflow hose. And now you can move your intake. There's a sensor you're gonna have to disconnect. All right, now there is a plug here you're gonna have to disconnect. Slide the red tab, push down and pull out. And then using the same 8-millimeter on the clamps, we're gonna take the bolts for the throttle body off. Remove your throttle body. All right, now's a great time with your throttle body off to clean the mating surface and the O-ring that will seat against your new throttle body.All right, now we're gonna install our new throttle body. All right, now be sure to reconnect all your electrical connections. And now it's time to put the intake tube back on. Gonna slide this back into place, plug in our air temperature sensor. And last but not least, we're gonna put our engine cover back on.All right, that's gonna wrap up my install of the BBK 78-millimeter Throttle Body and you can get yours right here at

      Better Engine Performance. Enjoy better engine performance by upgrading your stock parts to a BBK 78mm Throttle Body. This throttle body is designed to increase airflow for better throttle response compared to your existing Wrangler factory part. This is the ideal performance upgrade for both stock and modified Wrangle JK owners who want an increase in horsepower, torque and throttle response. 

      Premium Build. This 78mm Throttle Body is crafted from high-quality 356 aluminum castings that have been CNC-machined. This BBK throttle body also features a die-stamped throttle linkage, O-ringed throttle shafts, and double sealed bearings. New injection molded plastic ear assemblies are included for the “drive by wire” electronic control.

      Plug-and-Play Installation. The BBK throttle body features a straightforward direct, bolt-on installation and comes with pre-installed electronics for a no-hassle upgrade. It works with OEM air intakes and aftermarket cold air intakes to ensure perfect fit and excellent performance. Installation can be completed in under an hour with simple hand tools. 

      No Tune Required. These Power Plus Series Throttle Bodies are designed to work with a factory tune in most cases. Depending on ECM sensitivity on your model and other modifications, a tune is sometimes recommended. While it's not normally required, a tune will not only allow the vehicle to work with certain aftermarket add ons but will also improve overall performance of your entire array of upgrades to work together as a whole and can normally update such items as the factory torque limit functions.

      1-Year Manufacturer’s Warranty. All BBK products, including CAI systems, air filters, exhaust systems, headers and other products are warranted against any defect in materials or craftsmanship for a period of one year from the date of purchase. For more info, please visit BBK.

      Application. The BBK 78mm Throttle Body is compatible with all 2012-2016 3.8L Jeep Wrangler JK models.
