Is it worth getting this? or K&N type washable filters? I see inside the engine there are the disposable filters.... Any benefit with this? I remember years ago being told K&N filters adds about 5HP by allowing better air flow.
Worth getting? -COBB TUNING HIGH FLOW FILTER | 2014-2016 FORD FOCUS ST/RS (791101)
Haven't seen anything that warrants getting a high flow filter yet. In the Evo world it was noticed that getting a filter WITHOUT a tune actually limited performance/power. If you increase air flow but don't account for it sometimes good, sometimes bad (mostly seen bad).
Most times filter, tune, full exhaust yields some good stuff.
