OEM TMIC vs STI intercooler
Hello everyone. I'm going to replace the tmic on my 2005 blobeye wagon, as it's full of bugs, bits of tree and gravel, so looks terrible. I'm pretty certain the amount of crap stuck in it isn't helping it's efficiency. I'm not going for big power at any point soon so don't want to go down the FMIC route. So the options are either a second hand STI version (about £160) or an uprated OEM (also about £160) eg one of these from ebay:
My car has PPP fitted so I've already got silicone hoses. What do people think? Old STI or OEM?

My car is 10 years old, on standard internals so I'm not going to be going for that kind of power! My current intercooler is a mess, bent fins, bugs (and I given the amount of bits of laylandii I've found in the intercooler and engine bay I think someone once drove the car through a hedge). So it needs replacing, it was just a question of if I go for something shiny from ebay or something older but better. And I think I know the answer, so here's hoping father Christmas brings me an sti TMIC!

I have an ebay TMIC(the really big ones)..
tuner said it was great.. held up perfectly up to 450HP. even with no splitter.
This is on a GC8, P1 and a Fozzy STI.
It does heatsoak like mad.

But the next job after will be to get under the bonnet to give it a proper clean and sort out the IC. Using petrol is a good tip as I was thinking about using carb cleaner.

So, thus far I've got one vote for STI intercooler and one for ebay intercooler... still not sure what to do. The sti is proven technology, it's a common upgrade and low risk. The eBay intercoolers are more of a risk as there are a lot out there that aren't well made and may even reduce the flow and increase the pressure drop. But a good one may give benefits... I still don't know and I suspect that it's not going to make a huge difference...

I had mine modified (to fit on a V4...) by a company that makes/remakes intercoolers/radiators etc and even they said it looked like a good intercooler. everything was deburred, no ragged edges.
I ment Heatsoak when sitting still or in traffic i ment.. upon opening the hood after some driving intercooler is cold. it takes a fair amount of time to get it cold again once its hot. one reason is it sits more over the turbo, wich will heat it up when sitting still.
Buy what you want to.. im happy with mine wich costs less than a STI one with all the fins flattened

Takes longer to pressurise as its bigger. So you wont get full boost until further up the rev range which is bad as the td04 has no real top end power, its designed for quick spool at lower revs.
