I did a ton of reading on intercooler options for the R53, before settling on the GP intercooler. Some of the cheap ones could come apart and cause some serious issues. Many of the other higher quality ones heat soaked way worse than the stock one. Personally I would avoid this or any of the cheap ones for fear of subpar build quality.

The biggest issues I've read about after market intercoolers is pressure drop from poorly thought out air flow. It may be bigger but if the air can't get through it, it won't be better.

I run a GP IC with a Jeff Howerton Meth Kit and I only use 100% VP M1 Meth.
Meth does good things to your car without even being tuned for it. Cooler Air and fuel, and it cleaning keeps Carbon build up down. If you have your car custom tuned for it you can also take advantage of the much higher octane levels when its blended with 93 fuel.
It should be a must have on any 2nd Gen DI car.- Like x 2

I will need someone to confirm this. But I feel like I heard about this coming apart, like the welds breaking, etc.
I'm not sure if it were these though. But with a lot of things...you get what you pay for.- Like x 1

I didn't thank about it coming apart and sending a peace down the intake. That would be bad!
JMC40 you thank the GP Intercooler is better than this design?
I haven't done any research yet. Thanks for the help. -
I would steer clear of that eBay item. I mean, they can't even get an accurate description. Either they are being deceptive or it is just plain wrong.
Just go get a GP intercooler if you want simple and no maintenance, or better yet a meth kit if you want to force cool. -

Way has them also, $550.00 + $170.00 for the DDM diverter, honestly I like mine but 20/20 hind sight I would have rather put the money toward a W/M system.
The way I see it, unless you track the car, where you spend a lot of time in the upper RPM's, the stock one works pretty well, yes the recovery time with the GPIC is considerably faster, but on the street how often is it really a factor, going from a low RPM (hot) situation to immediate high RPM's the I/C doesn't really change things that much, between the GP & Stock you're prob. talking about a 10*-15* difference at cruising or low rpm/normal driving, and little or no difference standing on the throttle forcing air to the motor. Where as W/M you're talking about a Major drop, right when you need it.
Once my motor's rebuilt & I add the W/M I'm prob. going back to stock, if for no other reason than to be able to pull my plugs w/o having to pull the I/C everytime. -
I was looking at maybe doing W/M instead of a intercooler. I live in the south when it gets hot it really bogs down at red lights. Also at high boost I'm putting out very hot intake numbers. Maybe W/M would be a better way to go.
The only experience I have with W/M is a turboprop I use to fly a long time ago. When you hit the switch during takeoff it would sink you in your seat. The bad thing was when it cut off at about 400 feet. the plane would turn back into a brick.
If water/meth is like that I know I want it. Does anyone know witch system is the best?

Except for the GP IC, the OEM one has been shown to perform better than all of the others under real world use. Lots of better ways to get more power, inc. W/M injection.
-
As far as W/M for cooling purposes you can pick up an AEM, Snow or Devils Own system for less than the GPIC / DDM combo
But the best system out there right now is the Howerton Aquamist, you can get the hfs3 for about the same price as the combo + the resevoir, so prob. about $100.00-$125.00 more than the combo overall. -
I just took a look at the Howerton Aquamist web page. I think this is the way to go. I remember a thread about W/M. I'll do a search so I can read up on how to do the install and what size jets I will need.
Thanks for the help.
