Ak is seriously outdated, my friend. And I'm pretty that Aldy won't update it anymore.
There are other kernels that are being constantly updated, one more than the other:
1. There is "Hellscore kernel", which is updated from time to time by Hellsgod.

2. And then there is Quanta kernel which is constantly being updated by its dev, zaclimon, and it's very nice and stable.

Both are awesome and the best for our Nexus 4, at the moment.
If you want to try them both, you can't just flash one on top of the other cause you screw up everything. If you decide to do it, follow the instructions from the link below:
