A small gap about like what every one else is saying , My point was that I took the rubber all the way off and had a hugh gap all the way around between the air box and snorkel and it make no difference

A big gap , no gap , small gap has no bearing on any sensor or reading the ECU sees to make a change in any fueling or timing

Im not sure why some think this helps as there is nothing that this would change at all in the electronics or what the ECU sees , the intake air temps only changed by .5 to 2 deg with it all the way off ????????

But like Smokey says if it makes you feel better then do it

Not saying this is a cure-all or will help everyone. But:

1) I wouldn't expect this to make a differnce on the dyno. The theory is that, if a large gap is present, application of throttle after idling will draw in cooler outside air creating a lean condition for a couple seconds until the PCM adjusts.

2) By removing the rubber completely, you've created a good-sized spot in the radiator bulkhead for outside air to enter so the underhood environment isn't as closed as it otherwise would be.

Again, the issue is not hot intake air versus cold, it's the abrupt transition from one to the other.

To me, fixing this assembly problem (if it's present in an individual car) is no more than putting it in the condition in which it should have left the factory. It can do no harm and might be helpful. As I've expressed, it made a noticeable difference for me after driving the thing for 19,000 miles; certainly more helpful than most of the suggestions coming out of Dearborn.

This seems to help things a little, but it still doesn't fix all the slipping of the DCT after sitting in stop and go traffic for half an hour. I'm still convinced that the problem is one of heat and that Ford should have made the DCT a wet-clutch design. (And not an accidental wet clutch due to gasket failure )

after driving mine on a road trip this weekend, I think it handles take offs better with the gap taped. It could still be placebo effect, but i haven't noticed as much hesitation or shudders at low speeds.

Could be observation bias, now on each success i attribute it to the mod. So who knows? Given that it takes 5 seconds to do, why not?

We could test it to the extreme.

Completely unhook it and drive for a bit and then seal it up.

I'm not saying that this fix does (or doesn't) work, I'm just putting my data point into the pool that I have a gap and even when I push the parts together, there is still a gap (albeit small) near the middle.

Are you going to tape it? I've been slowly following your saga, and I'm curious if it will matter at all.

I appreciate the I dedication!

I will be taping it as a safety precaution, but I'm also getting my clutch replaced within a week. I think it's kind of moot to try to rush any experiments - especially if the warm weather and my stop-and-go driving don't really coincide.

More duct tape

To my surprise, my driveability issues largely went away. My car now behaves the way it should, with much better throttle response at launch and greatly diminished surging, bogging and lunging. ...
I always knew that the ultimate solution to some of the Mk3 Focus's "early production issues" would involve duct tape. Sometimes even just a little bit, when applied correctly, does wonders.

More fun, too.

Alrighty, did this mod today. Don't have any real issues with the car yet except crappy throttle response, but this is just cheap insurance. Used whatever I could find within 10 feet of the car, which happened to be 3M double sided tape. Left the red backing on so as to not leave a mess. Decided to use something with some thickness to it, for better..insulation or something, or some other reason that I've been trying to think of for the past 10 minutes to make myself look like a smarty-pants.

Nope, I was just lazy. Don't think i have any duct tape around. I like these little free mods that may have some method to madness, I may try stuffing my Sony sub with polyfill like the F-150's yet.

I'll report on any changes to the drivability tomorrow. If this doesn't liven up the throttle response from Eco-freako tendencies, an SCT tuner will.
