You're talking about an FI engine with different internals and a turbo vs. this NA. You can not just apply apples to carrot comparisons like that all over the place. Intake diameter, exhaust diameter, whatever you'd like.
It starts sounding silly. Under this logic, why do exhaust upgrades for example? Here is a similar statement: "I will repeat, a 2 inch diameter exhaust is perfectly fine to handle 281 TQ and 239 HP on a Crown Vic. That engine makes 130 lb-ft more torque and 80 hp more on a similar exhaust diameter to what is on a Focus. So seriously, that is more than enough for exhaust flow. "
Obviously, exhaust upgrades have proven more power for the 2.0L NA Focus.
Why even say it? The ST and NA engines are fundamentally different. The whole goal is to remove as much restriction in both cases, but the ST can cram lots more air through a small hole anyway. You still lose power if the turbo can't make your target boost pressure, but these aren't even similar cases.

So that engine is making 90 more hp through that same air intake. Plus the ST uses the SAME AIRBOX and filter.
So seriously the hole through the frame is good/big enough for any regular MK3 as far as airflow.
I do 100% agree removing the restrictive snorkle helps. And the free flow airfilter does too.

|bama_focus||Reporting back after driving around with the cap on the end of my k&n. Overall I miss the noise it made, but the powerband feels much smoother with the closed end. I am a firm believer that the stock airbox is efficient for this car and the open end just attracts hot air from the engine bay. Gunna keep my filter plugged until I want the noise back lol.|

|cjpasch||So if I do the delete, will getting a prefilter to just play it safe for water, will that undo the benefits of the delete.|

|schrodingersbox||Yes you can still do the delete, very unlikely for significant water to get in. Prefilter is like a jacket you can buy for your filter!|

|cjpasch||I have a k&n typhoon cai, can I still do the snorckle delete without worrying about water getting in there? What is this prefilter people are speaking of?|
