FSWERKS ITG Cool-Flo Race Air Intake System - Ford Focus Duratec 2.3L/2.0L 2003-2011

So far it has been pretty amazing! It definitely gives you way more power in the low RPM, seems like the car should have felt this way the whole time! One this is it leaks air quite frequenlty, it needs a small clamp for the top sensor connection on the intake as you just shove the censor inside the tube with nothing to tighten it down. Not a huge issue, would definitely reccomend! 2005 Ford Focus zx4 ST

Removing the old intake (2004 Focus Sedan 2.3L) was a matter of unbolting the various airboxes, tubes, covers, and snorkels. PZEV systems get crazy really fast. It took maybe thirty minutes. Installing this system is as easy as slipping the short silicone sections over the ends, securing them with band clamps, then sticking it on the throttle body and clamping it down. There is 1 bolt to be fastened, and a little mount is included as the new system is a slightly different shape at that location. Little tip: when you have the MAF sensor out of the old system, give it a spray of some MAF cleaner as preventative maintenance. The engine became considerably more growly with this system, throttle response piped up significantly, and you can hear a faint whoosh when you stomp the pedal. Torque below 2k RPM has also improved significantly, though some of that may be due to the "lifetime" filter never having been replaced in 207k miles. Worth all the money and then some. Get the "pre-filter" cover for it too, it'll make filter cleanings easier and less frequent and it's pretty cheap.

I was looking for a quality product to replace the factory lifetime air filter system.This product is high quality and fit like a glove. I decided to add the protective pre filter cover after. Car is definately more responsive. I would definately recommend it

Beware of the exchange rate plus the duty fees at the boarder if your shipping to Canada..was nailed with another 136 CAD before they let my package go today..so hopefully il get my stuff finally in 2 days..cuz I way over spent hope its worth it..will never get half my money back..no warning to knew buyers like me so writing this

Amazing! Must install for every focus owner. The install was super easy and took under 30mins to install. The immediate gain from throttle response is superb. There is a noticeable gain in torque down low in the rpms. The intake sound is amazing. The stealth exhaust coupled with this intake really made the car sound amazing.
