To start, here is a link to my how to thread: https://www.cobaltss.net/forums/how-...cooler-229313/

This Intercooler is PERFECT for what I wanted. In my opinion, it is perfectly matched for stock turbo with upped boost. I felt absolutely no change in spool time, and saw no PSI drop in boost. In order to properly test, I pulled the bumper and was completely prepped for removal of stock, then did a pull. Came home, swapped, and did the same pull, same road, same temperature outside. The temp difference was 18 degrees!!!! With an outside temp of 85 degrees, and at full running temp, I saw a high IAT2 of 98 degrees from a 3rd gear pull 80-140. On stock IC, I saw a high IAT2 of 116 degrees from only a 80-110 pull.

That was all on a hot week. Now that I have had it for a longer period, I have seen even better numbers. Here in KY, humidity is killer so keeping low IAT2s is vital for boosting. The other night, I had the privilege of being on a highway alone, and was able to ride out EVERY gear. After letting off at roughly 170, my IAT2 was a mere 12 degrees above ambient(48 degrees)!

Earlier in the same day (60 degrees), I went on a 100 mile trip, and my IAT2 was a mere 2 degrees above IAT1.

Overall, I can't compliment this intercooler enough. I have only seen IAT2s over 100 once, and it was on a 96 degree day, high humidity. I have watched it for weeks at every sort of speed in a plethora of temperatures, and my car is almost always within 5 degrees of ambient, and usually under 10 degrees of difference under harsh driving conditions. My stock IC almost always was 25+ degrees above ambient, and bogged hard core at high temps and humidity. A++++ rating. For a constantly overlooked or poorly engineered mod, I think that this IC was one of my best investments for my car, and I couldn't be more satisfied with the quality MPx has provided, not only for this IC, but also for the exhaust, valve cover, catch can, and spoiler I have got from them.

Some pics for posterity:




If you have any questions about this IC, or any other MPx products I mentioned, feel free to email me.

Hope this helps some of you make the right decision.

I have an MPX for a few weeks myself now and I absolutely love it. Great piece of machinery.

 

awsome price, fast shipping, great guys to deal with, cast end tanks so no busted welds, and it performs. Really no negatives i see

 

great review and great easy instructions to remove the front bumper.

 

Care to add anything?
Or am I spot on? haha
I took my fair time to record a batch of widespread and well recorded data

 

Thanks!
I took some pics because there was no real generic bumper removal instructions, and I like to reassure people

Thanks for those shots gestapo, I didn't have either of those and they are both very good to see.

I would also like to add that I did not have to alter ANYTHING to make the IC fit!

In case anyone wants to see more, I have pictures of ALL dimensions of both the stock and MPx IC in my photobucket album

 

Bump. I want you all to see its greatness haha

 

I've been running mine for a little while now and I think it is a really nice piece at a great price. But I do have one complaint about it. The end tank pipes are smaller in circumference than the stock ones. The stock piece measures at 2.5" in diameter and the MPx's were at 2.25". Not a huge difference....but it did force me to have to make a change in my setup for it to work. I'm running the Injen charge pipes with the better Vibrant couplers and T-bolt clamps. The 2.5" Injen pipe and Vibrant coupler with T-bolt was too big to fit and seal on the smaller 2.25" MPx pipe. I had to remove the Vibrant coupler, put on the Injen coupler and try again. The 2.5" T-bolt clamp was too big....it would not seal on the MPx pipe at all. So I had to take off the T-bolt clamp and go back the the worm-drive clamp. Luckily that worked. Everything is tight and sealed but there is a bulge in my Injen coupler because of the 2.5" to 2.25" piping. If I do blow off a coupler when in full boost, at least I know the first place to look.


You can even see the difference in pipe diameter from stock to MPx in your picture here:

 

I did have to tighten my hot side all the way on the t bolt, but the cold side seemed fine.
I have had a couple other people say the same to me, so it might be something to look at changing MPx

 

Has anyone else observed that this IC has a 2.25" inlet and outlet because it should be 2.5" just like stock.

 

Yeah why would you want a smaller inlet than stock?

 

All the other ICs are 2.5" not sure why this one would be different. Stock inlet and outlet are closer to 2 3/8" IIRC but most couplers are 2.5".

 

On our car, we measured the inlet and outlet of the stock intercooler and it measured 2.35 inch. Not 2.25 or 2.5 inches. Its pretty odd.

So, the intercooler fits well with the stock piping, but when we use it along with our Injen pressure pipe upgrade kit its a little loose because the upgrade kit uses 2.5 inch couplers.

2.35 is the size of the inlet and outlets. The lip on the inlet and outlets are 2.49 inches.

Because the Injen piping uses 2.5 inch piping we were forced to use 2.5 inch couplers, which is slightly loose on the factory intercooler and a tiny amount more loose on the MPx intercooler with 2.25 inch inlet and outlet.

As long as you have a good set of T bolt clamps, and you have a big lip on the MPx intercooler and or stock intercooler (which they do, both are nearly 2.5 inches it still will seal well.

We have tested our intercooler after installation and have found no leaks of any sort.

 

could you make a silicone coupler option that would have a outer diameter of 2.5 for pressure piping and 2.35 for your intercooler?

 

my couplers went on this IC just fine. i never even noticed a difference over stock. Im with dejon pipes, silicone couplers and T-bolts and stock cold side.

 

I also had no issues. I just had to tighten it a little more than usual, which makes sense

 

Nice review how's it holding up now? Any problems or things you wish could change? Im getting this with ZZP upper charge pipe can you forsee any fitment issues? Instead of making a new thread the search button found the exact question I needed I'll just ask the few additional questions here.

 

goooooood write up for sure, sold me and my IC, buuuut i have on question, does it hang any lower than the stock ones, ground clearance i mean???

 

I have one and it's worked very well. No, it does not hang down lower than stock. In fact, it's one of the few intercoolers available that does not hang down lower.

 

Any chance the 2.5" piping thing can be corrected in the future?

 

It may hang a little lower, but it would never scrape unless you are jumping the car.
I am not sure if they ever altered the inlet sizes, but other than that, nothing I would change

 

has anyone tried a 2.5 to 2.25 coupler for the hot side inlet?
