With our Jeep engine out for replacement, we figured it'd be a good time to install these 8-hole injectors from the newer 3.6 PUG engine P/N: 05281427AA. They should theoretically improve atomization, which should improve fuel economy, reduce misfires, and produce better off-idle tip-in response. They come with new O-rings too, which is nice.
They dropped right in place of the stock injectors without any trouble:
The decision to run these injectors came after reading all I could find about them on various forums and Facebook groups. It seems the few who've done it are reporting a 0.5-1.5ish MPG gain in a JK and as much as 3 MPG in a Charger. Having just installed an 8-speed auto in our JK Rubicon, the data may not be as apples-to-apples, but we'll see once it is up and running and then report back here with the results.
