      Video Review & Installation

      Hey, what's up guys? I'm Ryan from ExtremeTerrain. And today I'm here with the BBK 62 millimeter throttle body for your '91 to '03 wrangler. This is gonna be for someone who's looking for a little more power and throttle response out of your four liter and it's gonna be an upgrade over the stock throttle body. And you're gonna get more out of it than just adding a spacer. For the same price as a stock throttle body, you can upgrade to this unit. And for just under $300, I honestly think this is one of the best options to go with. This is gonna be an easy bolt on that comes with brand new gaskets and hardware to install and it's made in the USA. As far as install goes, I'm gonna give this a two out of three wrenches as you can install this in under two hours with simple hand tools. That being said, let's hop into the install. First step, we're gonna remove our factory intake tube using a flathead screwdriver. There's a clamp around here. We're gonna loosen that. Next we're gonna remove the PCV hose. This most likely is just gonna wiggle right off. Next we're gonna remove these clamps, disconnecting the top section of our airbox to the bottom. Then we can remove the whole assembly. So we're just about ready to remove your throttle body except we are gonna have to disconnect a few connections. This is gonna include the return spring, the throttle linkage, and then there's three plugs on this one. So we're gonna push down on these locking tabs, unplug this. Next we're gonna remove our throttle linkage. That's just gonna pry off to the side. And then our return spring. It's gonna pry off frontward and don't lose that. Now, this is not gonna be on your stock. This is for a hand throttle. You probably won't have this on your Jeep. We're gonna go ahead and remove that as well. After everything is disconnected, you're gonna use a 10 millimeter socket to remove your four bolts. With all four bolts removed, you're ready to remove your throttle body. So we have our stock unit out. We're just about ready to install the new one. However, I just wanna take a moment to cover some of the features that you're getting with this new one. Now, the stock throttle body is 55 millimeters on the inside. This new one is gonna be 62 millimeters. Even though the stock throttle body is 55, the hole in your intake is actually 62 millimeters. So this is gonna give a smooth transition for airflow. Not only is it gonna boost airflow, but BBK claims power increases of up to 12 horsepower with this. It's machine from rustproof 356 aluminum alloy and is much stronger than the stock unit. Not only that, but it comes with double sealed bearings and O-ring throttle shafts for a longer life and smoother operation. BBK provides you with new gaskets. So we just need to switch over some of the electronics and then we can get this thing installed. So now we're ready to switch over our sensors. We're gonna begin with the IAC motor. We're gonna use the security bit that they provide in the kit to take these four screws out. So now that we have all four screws out, we're gonna go ahead and pull this piece off. Now they give us a new gasket to install on to the new one. Next we're gonna switch over the MAP sensor. You're going to use a T25 Torx. Once you have that off, you're ready to switch it over to your new throttle body. So we're gonna start by pressing that on. So now that we have our throttle body assembled with all of our electronics, we're ready to install it. We're gonna place our gasket down, throttle body, and then we're gonna use the new bolts provided. We're gonna tighten them up with a five millimeter Allen key. Then we can hook up our linkage. We'll start with our return spring. Slide that on. Hook it onto our bracket, then we can take a throttle cable, clip that on then we can plug in our connections. After you have your throttle body tightened up and everything's connected, you can put your factory air intake back on. Then we'll tighten our clamp up, reconnect our PCV, and then we can latch our airbox down. So with everything put back together and tightened up, that wraps up my review and install.
