I have fitted Do88 and APR an no trimming is required as your installation manual instructs
Reviews of APR intercooler
APR has been rock solid for 25Kish miles for me in S FL heat. Consistent rapid heat dissipation (compared to stock), wouldn't drive a stage 2 (or higher) car in ambient temps like down here without an IC upgrade. I've watched oil temps drop from 225+ after cruising at 80ish for an hour down to 210 in < 1-2 minutes, at 90+ ambient temps. Seems to work for my setup.
APR fits like a glove, no matter if you have the “ribbed” end tank radiator or revised “smooth” end-tank radiator. Some others need dremeling and/or tell you in the fine print that they don’t fit certain radiators. I installed an APR IC on my previous .:R and also on my current one, and each time it installed without any fuss.
It was on 4thgear Every pull was after a reset I wanted to see if the APR Intercooler would keep up and wouldn\u2019t drop power after a couple pulls and it did
I'm glad to hear more positive results with the APR IC! I'm going to experiment with how much my fueling setup likes ethanol, but I'll probably still get a simple wmi setup just to drop IATs. I went out and did a few pulls tonight and holy **** this car is pulling strong.
Thought I'd add my 2c as I've had an SB stage 3 daily + APR stage 2 (IC, DP, full intake, etc.) for about 5K miles now. Noise, yes. Annoying - could be, depends on individual tolerance, I suppose. The sound reminds me of other tuned cars I've driven that had more power than sense, so I like it. AC on at idle w/clutch out is probably gonna trigger a lot of folks who prefer quieter. Hold - 5k and no signs of any slippage whatsoever, and I regularly (like daily) hit 30+ indicated (P3) psi boost. I like to enjoy the power of the sleeper. Pedal force - yup, it's a STIFF aftermarket clutch. It got better after about 600-700 miles break-in, but it is a firm clutch. The one dude I've let drive it (who daily drives a Hellcat auto and has some vintage manual cars) just about sh$t himself when he first felt it, then eventually agreed it's damn firm but appropriate / proper for a tuned car to feel like that. Cost - yep, it's not cheap. I had USP in South FL install it along with the IC and other stage 2 related goodies, so the bill was up there. Fluidampr as well, which I think is a must with this setup, can't imagine how it'd sound without it. Probably like a friend's well-tweaked '01 M3 (E46) n/a with ~410 HP. That thing clattered with the clutch in at idle but what a beast. Overall, it's a compromise for those who want to tune and obtain more power from the platform. I was at stage 1 low torque on the OEM clutch and knew within 500 miles that wasn't gonna last, so I planned and budgeted for the clutch + stage 2 and will be quite happy for a while with this setup. One other item of note - APR stage 2 v 2.6 is a quite a bit LESS aggressive with throttle tip-in / response, so much so that I was contemplating quite seriously going back to 2.5, but after driving and living with it for a few weeks I'll take the better MPG (by close to 1.5-2) and smoother up top response that the 2.6 tune has returned. This is at the penalty of super-fast pedal response - but I've re-trained my right foot and all is well. I'd be interested to hear what others have felt about APR stage 2 v 2.6 on a manual. Not a lot of threads on here that I could find, though one was pretty critical.
You mentioned heat soak is an issue where you live so there's your answer! IC was already my vote before I even read that part of your post.
I don't understand how the upgraded intercooler is making the car actually faster? I understand keeping temps more stable or even cooler with more boost helping to preventing heat soak, Resulting in more consistent power but how is the motor actually making more power in already cool (ideal) conditions?

I chose the APR intercooler to replace my current intercooler setup (OEM intercooler with add-on Forge Twincooler). I have to say, after seeing pictures of the APR intercooler online then finally holding it in person, this thing is massive.
