DIY: Berk Technology HFC Install

370Chicago · 06-08-2017, 07:22 PM

Just put mine in over the weekend! I've been looking at them/the box for 6 weeks and was a bit nervous about the demon bolts. Finally I said screw it and gave it a try, it really wasn't too bad.

Here are my tips:
1) PB Blast the heck out of everything. I can't say for certain that this helped, but for $4, it certainly didn't hurt.
2) Use the right tools! 1/2" drive where possible and only 6 pt. sockets! Make sure the socket is well seated before trying anything.
3) Remove the air box and tubes. A lot of guys talk about using a universal joint, but that eats up a lot of energy. With the air box and tubes out of the way, you can get a straight shot at the passenger side (use 1/2" parts). Driver's side is a bit more difficult, but doable. I used a 3/8" socket and 3" wobble extension against the bolt (you can't really use 1/2" drive as the steering column is in the way), then converted to 1/2" drive. A 3' breaker bar did the trick.

Took me and my wife (both lawyers...) about 3 hours from start to finish, so if a mechanic quotes you anything near that, don't walk, run!

My take away is that if you plan properly and use the right equipment, there is no need to be worried.

The result has been great. It's probably the largest "gain" from any bolt on I've ever installed. The VQ "hiss" is annoying from 3-2.5K, but it's a fair trade-off.
