What I've done.


  • KN Intake (Cause I love oil on my MAF sensor <3 ) I actually put the resonator back in today. The resonator surprisingly makes the short intake a lot more quiet, but I was tired of dust getting on that insulation.

  • All the LEDs.
  • DEF is sort of disabled. It won't trap me at 4 mph limp mode in theory.

That's it :(

What I am working on


  • 2.5" DownPipe (should probably double check that, I am pretty sure its 2.5"), 3" DP-Back, with either a 4" magnaflow muffler. Mostly stainless steel.

  • FX-R Retrofit with 5500K bulbs. Afraid of heat, so sticking with 35W.
  • Replacing the godawful Pioneer 6x9s. (or maybe I just got a bad batch)

Distant Future


  • Turn DEF Tank into a lawn ornament. Carry around a spare tire instead.
  • 250 HP Goal
  • Bigger badder fixed turbo

They make an intake for the CTD?

Sort of. They are what I call "Short Intakes" which are cheap and take air directly from whatever happens to be in the engine bay. The factory intake is a cold air intake as it takes air from the outside, but it's like sucking threw a very thin straw.

Amsoil and KN (who are both the same company) make the intakes. Amsoil is dry, KN is oil. Otherwise the two are exactly the same.
A few people have posted build threads in this section, with pics and details. I think if you search the words diesel and build you should be able to find some of them.
Yea I'm prolly not gonna put an intake in my in sure it really opens up the air flow I wanna do HID or LEDS but I'm worried about the DTRL and how they will affect the lights

I think some people just made the headlights full power 24/7 else you will need a special relay to hook up the HIDs. LEDS I am guessing would just plug right in. Of course people on here will scream at you for not using projectors. The Diesel is almost exactly the same as the Gas except for the actual engine, so you can see what people did with the other models.
It's not a freakin' "TDI" engine.

Not that I've seen. I know someone with that setup and been fine for a year now.

Wait, I am confused.....did you eliminate the DEF/DPF?I would love to go with a bigger DP but no idea where to get one or who makes that, the midpipe and the tune to eliminate all the stupid DPF.
Fleece performance makes a down pipe and race tune

Yes no more dpf or def
Search member Danny5 for his extensive build thread. Lots of useful info there.
I just picked up a 15 diesel. Tinted windows, interior led's. Led headlights. Want to remove the bow-tie from the rear and black out the front one. (Ideas for that would be appreciated). I'm gone do wheels at some point. I want to use the stock wheels for winters and get something else for summer use.
