Do not listen to this guy. The longevity of your car will be extended considerably with an Intercooler. Once your intakte temps reach about 150 degrees, with the stock intercooler and stock tune, your car starts to dump fuel into the cylinders to cool the motor. Thats the only way your car can control those temps with the stock intercooler. At ST Octane academy, Ford Racing changed out the intercoolers on the Foci and they have been beat on for 7,000 miles. With that being the only modification. So, if there is only one modification you do, do the intercooler. If you want to save your clutch, do the RMM also. I found that out the hard way.Don't do it. If reliability is a concern i wouldn't touch anything aftermarket.
and this guy is a supporting member? Oh lawdDon't do it. If reliability is a concern i wouldn't touch anything aftermarket.
Again I will second what I originally said. Not to bash on anyone but clearly the op is new to his car. It's never a good idea to just start swapping parts if you have no clue what's going on. I never said anything about the stock intercooler. With asking this question I would imagine he won't be doing the install. So maybe 800 bucks for a intercooler on a bone stock car for reliability I wouldn't do it.
About how long does it take to install an ic, some guy said he can do it in about 30min to an hour, not sure if thats a reasonable amount of time to install it.
Firstly, where do you live and how hot does it get? Next do you drive the car hard and do third and fourth gear pulls? or is it just a daily?
Before spending money on an intercooler, do you need one? if it's hot and/or you drive it hard then yes you will benefit from an intercooler. Notice how I said benefit and not 'errrmmmaaaggeeerrrrrddd must get it cause I have it and it's a depo and my charge temps errrmmmmmaggerrrddd'. I have seen plenty of stock ST's with 140,000km+ using stock intercoolers. This is in Queensland Australia where it gets to 42 degrees Celsius (107 Fahrenheit) for periods over summer. So on stock tune you should be fine, yes believe it or not Ford actually did put some sort of engineering into this car, a lot more than many of the companies you see flogging their generic china cores with welded end caps. So in stock form if you don't live in a hot climate, or if you do I have not seen a stock car kick the bucket purely due to the intercooler (not saying it hasn't happened, I have just not seen it), you should be alright provided your driving habits aren't nuts or your car isn't modified.
Run good fuel, service at regular intervals and let the car warm up before you get on it. An intercooler is definitely a nice to have and becomes a necessity once you start modding, but for stock trim I haven't seen any proof of reduced longevity and the evidence is in the used car market. Of course you will get those that have started modding or monitoring their temps and change intercoolers and want to justify it to themselves. It's your decision at the end of the day. An intercooler is a good upgrade but in stock trim, unless you live in a really really hot climate I haven't seen any proof it's a must for longevity.
Note that when your IAT is high the car pulls timing so just because you get a high IAT doesn't mean your motor is going to blow up. You may get heat soak because of this.
No power goals in the immediate future, no issues with a heat soaked stock unit no need for a aftermarket unit.I'm almost at 4000 miles and i have never passed 6k rpms lol. So no, i rarely ever do hard pulls and just drive it normally (faster then most but not pass high rpms). And i do live in a place where it gets very hot (100s) but now winter is coming will an intercooler still be a good idea?
Easiest way to test it, go as soon as you can today and get on the highway. Put it in 4th gear at like 3k rpm and gun it. Run it to like 5500 to 6000 then slow way down so you are back at 3k quickly...then do it again. You'll instantly notice how much slower your car is and it will have way less power the 2nd time. That's heat soak. Our stock intercooler is terrible and 96% of this community will agree. There are a ton of people on here who have changed the intercooler on a stock car and run it that way and even get warranty work done, but if you're worried about warranty issues keep the stock one and if you need to, the install is easy enough you can put the stock one back on before taking it to Ford. Trust me, the intercooler is a good idea. Better safe than sorry wins out 99% of the time. Heat soak sucks, hence why the Ford Octane Academy have aftermarket intercoolers on the stock tune.I'm almost at 4000 miles and i have never passed 6k rpms lol. So no, i rarely ever do hard pulls and just drive it normally (faster then most but not pass high rpms).
