I just put mine in last week. Demintion wise it is about the same as stock but two inches thick and you will need to do some modifications to get it to fit. First, you will have to mode your AC condenser down. This is done by putting it under the stock brackets instead of above. Second, you will need a drummel or a grinder to adjust the radiator mounting brackets. Other then that it went in great. None of the modification work was very time consuming or hard.

could you do me a big favor and measure the lenght of the koyo radiator the next time your near your car, thanks

That won't be untill next weekend but sure (long story). When I pulled the stock radiator and switched the fans the radiator's were about the same size lenght wise. There was no major difference between it and the stock one.

Out of curiosity, why do you ask? I'm curious what you are going to do with it.

There have been soooooo many threads about this (Well, at least about the fitment part of it) and now that the search function works again...

Any way, when I put my Koyo in all I did was switch the L and R mounting brackets and slightly bend them. That droped the radiator down further than the stock one was and everything went back together and fit even better than before. If anything the Koyo is angled down slightly more than the stock one was.

Put my Koyo in last week, no problems (except my dumb *** got the mounting brackets on backwards the first attempt!!). No clearance issues at all on anything and I have a stock setup in that area right now.

Install took some time, only need a lift to get the fluid out and then only as a convience. So if you are planning a stock install, you will be very pleased.

Only time I had questions on fit was when I put some pressure to get the radiator in place, then it just popped in. Only problems that I had was the obvious bracket issue and getting the drain plug out of the old radiator.

The Koyo is much bigger (have pics that I took, not back yet) in width, everything else is just like stock as far as dimensions.

Be very careful with the AC Lines, don't bend them too far or you will break one.

I'm trying to make some airsheilds for different radiators (to channel 100% of the air in to the radiator). Actually it's suppose to be a cuztom thing for some one which is gonna get a koyo but does not have one yet. Right now I only got stock radiators (3 of them hehe) so I wanted to know if there was any difference in them. I think for the sides I got them right but as for the top and bottem, I don't know how wide they are for a koyo radiator.

btw, thanks for the info

becareful of your SMIC, the koyo core presses against the radiator fan and kills the motor. it happen to me 2 times. Had to have my radiator lowered even more.

Well, I managed to get some of my pics back on my Koyo install. Believe that there is still one disposable camera missing, but some pics were on the ones developed, so I will try this pic link thing, no promises.

File was too big, will make it smaller and, one more time!!
