I bought a koyo radiator not the n flo. I have the stock airbox and Intercooler duct. Stock intercooler. How can I install and modify brackets so that I do not have to cut up the duct or airbox? Sorry I have searched all week anf can not find a direct answer on how to modify the brackets so that the radiator sits low enough to clear.

 

I unsuccessfully tried to install a Koyo in stock configuration as well. It is a serious pita. Some guy claim it dropped right in but I think they are full of ....

Going from memory, what I think you need to do is to drill a new hole in each of the upper/forwardmost brackets beside the existing hole so that the top of the radiator sits lower in the bracket. I think Banzai Racing posted some directions once but I don't have time to search for it right now. Not sure if there is any further in the 3rd gen FAQ thread on this specific issue but take a look at it to make sure.

 

Here is a very detailed how-to with pictures for installation into a stock car.
