being that i'll be taking my car to trackdays in the warm california summers i'd assume that this would be a worthwhile mod after my warranty is done?

I find it is hard to exactly estimate this on my car since I am trying to document the install. I suspect it can easily be done in under 4 hours though from start to stop. It is not a difficult install, but the prep does take a little time.

Thanks for the kind words SloMaroZ! I think the N54 just runs too hot, so I think it is a great mod for any N54.

Former_Boosted_IS: I was wondering if you possibly checked that the thermostat in this kit allows oil to flow to the oil cooler when the oil is cold. If not then I'm afraid I'm definitely not going to use it. (I have one...)
I believe the original thermostat allows oil to flow BOTH directly to the other side of the thermostat housing and through the oil cooler line. When hot, the thermostat closes and only allows oil through the oil cooler line. If it does not, then what you are doing is giving your engine a shot of cold oil, (ie. on a cold day,) once that thermostat does open and allows oil to flow through the oil cooler!!! I don't think this is a good thing... |

This will take a lot longer. You have to remove the cabin microfilter housing, the air intake, left charge pipe, at least disconnect the throttle body, and remove the intake manifold to get to one bolt of the oil filter housing. (I know because I'm in the middle of trying it. I'm stuck on the charge pipe.)

What you are describing is basically how the thermostat DELETE works. The OEM one will flow oil both back in the engine and oil cooler when its open.

This is the identical way the stock oil cooler works. Notice the picture of the stock thermostat housing below. It blocks off the path completely to the oil cooler when the thermostat is closed. |

This is how all coolers work with a thermostat. Radiator, oil cooler, etc. All other car platforms that add oil coolers use the same thermostat concept as STETT. This method is used on all cars.

great write up, i'm not sure if its mentioned here cuz i didnt read all the replies, but that bracket you removed that interfered with the oil cooler bracket is the support for the headlight so it doesnt crack tabs, you may want to try to make a bracket to work with the oil cooler brackets so your passenger headlight doesnt crack the tabs

it was added to 08 and up cars because the 07 coupes were cracking tabs ALOT. you will probably be fine, but i figured i'd mention it in case anyone follows the diy and plans to remove that bracket and later down the road wonder why their tabs are cracked

Unfortunately the Dinan oil cooler also seems to require removal of this headlight bracket if anyone is considering that route. (I don't have the VK one to be able to tell on that one...) |

Anyone following this as a DIY:
I just left the horns on the crash bar, disconnecting the electrical connector. I haven't put everything back yet but it seems to be okay to do this. The bar comes out just fine with the horns left on it. When you drill out the rivets, go straight to the 3/16th inch bit. I tried from very small increasing the size incrementally, and the rivet started spinning with the bit, (I think one size before 3/16th)! It became very hard to drill out, and after finally reaching 3/16th and a lot of time, the head finally came off. Someone asked: The Dinan cooler uses the original mount, but if you don't have the stock oil cooler you will have to take off the crash bar to attach this mount. |

Great DIY. Does anyone have a DIY for replacing the factory oil filter housing? My car did not come with an oil cooler and I've been searching for days trying to find instructions on replacing the no-cooler housing with the housing that can accommodate the thermostat or the STETT delete place to add a cooler.
TIA |
