2014 Focus ST

What dyno results have people seen out there with.
91 octane tuners - which has best results and drivability since this is my daily driver.
intercoolers - what kind of gains and do you experience any lag issues?
air intakes - what kind of gains and do they keep the dirt out?

Thanks for your time,
Joey

Hey, welcome!

A tune is going to be the best on that list, followed by the intercooler. I personally use Justin at Freektune for mine, but Randy at Mountune is also good, FSWerks, etc. Power is near identical between the big tuners and drivability can be tweaked to your liking on all provided you get a real tune and not a baked OTS map.

Zero lag issue on the intercoolers and they all perform near the same. Don't spend big $$ here. The CXRacing cores work great and I believe Panda sells them with the proper elbows welded on.

No gains with an intake, so pick the one you like the best. The dirt will depend on the filter so stick with a good filter. No eBay Spectre crap. ITG, K&N, Green all make great filters. I have the FSWerks and like it, but uou can get the same power gains staying with the stock box and putting a good drop-in inside; Similar to what works best on the SVT.
