Need Help with BMW Performance Radiator Install

Hi guys, I'm planning to have my mechanic retrofit this additional OEM radiator to my 2007 335I sedan sport package: http://www.realoem.com/bmw/showparts...38&hg=11&fg=95 I won't be getting the fan, so I just want the radiator, and air scoops. So far these are the parts I'm going to order:

-Radiator (17117602241)
-New hose to the pump (that Ts off to the additional radiator) (17127602294)
-New hose from the heater core to the main radiator (that Ts off to the additional radiator) (64219222129)
-Bracket for radiator (51647154545)
-Air Scoops (51742157672)

First of all, are these all the parts that I need? I think I need some mounting hardware. Is this all the mounting hardware I need: (Hex nuts and bolts)--> http://www.realoem.com/bmw/showparts...=17&fg=05&hl=1 or do I need to order more? do I need, that plastic at the bottom of the long radiator? do I have the right part numbers for the air scoops, and will this help lower track oil temps on a non-oil cooler 335I?

In case anyone comes across this thread in the future, the correct part number for the bracket for the radiator is 51647975360, not 51647154545. The 545 part has shorter studs on it that will not fit through the mounting points on the radiator.

If you don't have an oil cooler, this won't be nearly enough for some track abuse... Get an oil cooler first before doing this.

So far I have managed the avoid any limp mode but running the heater on max and cycle the water pump and radiator to max speed through JB4 max cool mode. Worked alright in cooler track temp, but when it is approaching 90f out there I still have to do a cool down lap every now and then.

My approach is upgrade the stock oil cooler to the Dinan one which I got it for a deep discount (good kit). Still deciding to whether just run aux radiator as it is, or use the supplied hose to route a bigger core. See this thread that I made http://www.e90post.com/forums/showthread.php?t=1048496

Also ecs sells the full kit, http://www.ecstuning.com/ES2770373/

You just need the air ducts and vents specific to which front bumper you have.

So yeah, this thread is from 2010 so I think the OP is long gone. I was just posting for posterity to help anyone searching not make the same mistake in ordering the bracket.

In case you are curious, I am planning to use this radiator core as a second oil cooler that I will plumb in series with my OEM one.

Could you help me fine the parts number of New T-hose to the pump for N55 engines? I have the 17127602294 but just found it's for N54s not for N55

I am honestly not sure. I have been basing my P/N's on looking up for a 335is which has an N54 in it. I would check to make sure that the part numbers for the N55 and the N54 for these hoses are different. I suspect they are the same P/N though. Use www.realoem.com for part lookup.
