SRH1776 Your guess of 11 hp is probably pretty close. The larger issue is that without the heat shielding that comes with some of the CAI, you'll recirculate hit air from the engine. I've tested this with my engine Tuner and it makes a difference. I would also look at the Newmission thread. I mocked up something similar for my CAI and it really helped stabilize the temperature fluctuations.

FordFocus3 So I heard that a simple swap with the OEM filter, gives the K&N a 11hp gain correct? I'm thinking of a drop in K&N and putting on a mini snorkel from the ST, along with deleting the resonator below the air-box and plugging the hole... Thoughts as to gains?

You mean the factory air box and the K&N? If so, here is mine covered by an Outerwears pre-filter

It feels/sounds like the car is breathing easier now.
The OEM filter is horrible for flow. I feel really bad for those individuals that are still runnung them on 87 octane in the hot temps with the ac running

dyn085 Lol, it's all good I decided to create the dyno thread to try and consolidate some graphs, but I don't think it's much easier to read.

The best numbers I've gotten were from the K&N, Snorkel delete, and ram-ish mod at around 70. That was the first round at the dyno. My assumption was that it was the filter. After going back to re-test in multiple configurations-that is when I found out that there had to be a combination in order to see the good numbers. All subsequent runs have been in higher temperatures, so I am topping out a bit earlier.

If I still have access to the dyno then I will document some more later in the year once temps cool down. Any more at theae temps is pretty much worthless to me.

Sorry, a bit off topic...

I read again your thread and now I get it (I hope): You dyno-ed the car (stock) with OEM filter on, then switched to the K&N filter and did the mods (snorkel delete and ram-ish thing) and you got the final dyno results. If so, I don't see why your numbers should not be good. All has started from my misunderstanding; I thought you dyno-ed the car with the snorkel delete and ram-ish thing on it and the OEM filter (stock), then you changed the filter and you got those 10+ HP/TQ numbers.
Sorry for everything - it was not my intention - I am a little slow because it is too damn hot/humid here in the North.
