So, I ran the Red Line and CRC through the system. I shot the CRC in a vacuum port just before it went into the intake manifold. All I can say, for me, is the ST seems to run a lot better. It idles very smooth now and no longer hesitates when leaving a light, accelerates smoothly and runs down the road very smooth. Your results may very.

Here's what I found. Yes, CRC Intake Valve & Turbo Cleaner is generally safe for plastic parts in the intake system , as it's designed for GDI/turbo engines and specifically states safety for turbos and intercoolers, but always follow instructions, avoid spraying directly on the MAF sensor, and change your oil soon after, as it's a fuel system cleaner, not an oil additive

I purchased a can of CRC Intake Valve & Turbo Cleaner. It says to spray it in after the Mas Air Flow Sensor or into a vacuum line into the throttle body. Does anyone have a suggestion on which vacuum line I could use? Would it be better to just spray it into the air tube after the sensor? I used a bottle of Red Line Complete Fuel System Cleaner and that seemed to help with the hesitation, but I wanted to clean everything. I have a 2020 ST 2.7 with 35,000 miles on it. I replaced the trans fluid, PTU and RDU fluids at 30,000 miles. Car shifts great. Thanks for your help.

I got it back yesterday and everything works fine. They kept everything, I didn't need it. Warranty, yes.

I am new to the form because I just got my 2020 ST. It only had 3419 miles on it when it arrived from out of state last week. I only got to drive it 4 miles to the gas station and back. It started overheating so bad the over temperature screen came on. No Check Engine Light though. I spoke with the used car dealer I purchased it from and he said he drove it for a couple of hundred miles without any problems.. I had it towed into the dealer, thank you Roadside Assistance. They said the thermostat was locked shut. After that they found that the radiator wasn't flowing properly and they are replacing it. The service writer said that Ford was going to want it back to see why it's not flowing properly because it's so low miles. I do like the ST with the little bit I was able to drive it. The question I have is has anyone experienced something like this with their ST? Thx

Thank You

I know it's been a while, but do you still have this cover. I just purchased a new to me 2020 ST with only 3400 miles on it and I would like to get one of these. Thx
