The big Intercooler thread.

[Ambient Thermal Management]

Upgraded my ETS to ATM and really felt the difference. Much better at throttle tip in. No more slight lag. Temps stay cool during a pull. Cruising temps stay cooler as well. Overall a damn fine product.

Thank you for the feedback! There's some other comparisons on this forum as well

For the people who have removed their shutters to go with a larger intercooler, have you noticed any drawbacks to doing that?

The shutters are there for fuel economy when driving more calmly, as it increases aerodynamics

CjPony Parts has the CP-E delta core on sale for $370. Should I snag one?

FWIW, 2018 Performance Pack cars did not come with shutters. They are not "critical" to anything.

...and I respectfully disagree with this statement. I live in Florida, which is the humidity capital of the US, and even the Mishi has done wonders for heat soak on my car with both the FP and stock tunes. If the plans are there to continue modifying the car, by all means go big or go home. When you're talking about running the stock turbo that can only breathe so well to begin with, going too big is like throwing a hotdog down an open hallway. A few degrees of difference in IAT doesn't make up for the pressure drop across the intercooler, especially with the stock tune.

Does a wet heat compare to a severe dry heat?
It's is all to common for Arizona summers to reach 105-110° which is really what has me worried about mishi's smaller intercooler

Only that I see a code when I plug in my OBD2 scanner. I’ve thought about sourcing the connectors, and making a resistor pack to eliminate the code, but it hasn’t bothered me enough yet to actually do it. I’ve got a stock fit intercooler, and still pulled the shutters, only benefits for me.

Absolutely! That’s a damn good price. I’d look hard at that or the ATM blems mentioned above if you really want more face area but not the full blown large intercooler.

Heat is heat, but a wet heat is more of a struggle for the turbo itself than a dry heat. The intercooler is going to shed heat regardless of the humidity level, as it uses the temperature differential to help pull the heat out of the air inside the unit. In Arizona, I’d be more concerned about getting the stocker in the trash as soon as possible than I would which one I replaced it with

Having gone through an az summer last year I can safely say that the car won't die cause of it but the stock ic definitely can't keep up. No matter what when the temps go above 100 timing is pulled like crazy. While I do not have one yet I fully believe that a smaller unit like the cpe will do nearly as good of a job as a larger ic.

I will be going the cpe route in the future when I decide to mod the car. While you can opt for a larger unit I think that if your not planning on a turbo and engine upgrade it's just pointless. Just my two cents

Couldn't agree more @Cardude99

Totally agree - this dude intercoolers!

I thought I'd post this here for future reference. I just purchased and installed a G-Plus intercooler on my 2018. Yes, this is one of the inexpensive Chinese intercoolers sold on Ebay, $323 shipped. My engine is 100% stock, no tune, etc. My only objective was to prevent power loss due to heat soaking during HPDE events.

General observation on the intercooler itself;
- Appears well made, decent welds, etc.
- No hardware provided. You need to get a bolt to attach MAP sensor.
- No diverter blades in the input tank. Without this, I suspect very little air will pass through the upper part of the cooler.
- Heavy! 30 lbs, vs 6.5 lbs for stock.

Install;
- In the description, they say this can be installed without removing the bumper cover. Impossible. The cover must be removed, and the steel impact beam as well. (Note: Removing the bumper cover on a 2018/19 is slightly different than earlier cars. Instead of a single screw attaching the corner of the cover to the fender inside the wheel well, there are two 10mm nuts that are accessed from the engine compartment. None of the install videos mention this.)
- Fit well with no modifications necessary (Note: I have a Perf Pack car, so no shutters)

I really won't be able to speak to it's effectiveness until I get it out on the track (Road America in May). Especially with the sub zero weather we've had lately, i.e., you could probably run no intercooler and be fine!

Thanks for this. Unfortunately the issue with eBay no-names is what you mentioned: no accessories and they just put whatever in the description (true or not) and you really don't know the composition of the metals without running it (I suspect that's why you hear about cracked welds after a while). I'd be interested in seeing actual data on the performance, though!

Fortunately, an intercooler is a pretty simple device that is not highly stressed, i.e., you can see essentially what it's made of. I might be more concerned if I was buying internal engine components, such as pistons, rods, crank, etc. "Proof is in the pudding". If it allows me to maintain full boost longer, to slightly higher revs, it will be money well spent. I'll certainly post a follow up in May.

Worse quality intercoolers inhibit flow more and cool less though.
