I would say anything 3/16", and over would be improved with a mod kit.

I added paddles to my snow thrower a few days ago and it hasn't snowed so I can't tell how much increase in distance I achieved, but my gap was 5/8" and I brought it down to 1/8". The smaller your current gap the smaller the benefit you can achieve.

One thing about gap you should recognize is that the gap may not be uniform all around because the tolerances on the housing as it's screwed onto the machine can be off a little. Beyond that, see if you have any bolt heads inside the impeller portion of the housing. If so, you'll have to allow for them which will mean you may not be able to get the gap as tight as you anticipate.

You should be able to achieve some benefit my adding Pam or some non-stick lubricant spray inside the housing. This can reduce build-up of ice around the impeller and can improve throwing distance.

Most importantly, though, are you satisfied now? If your snow thrower tosses snow 15-20' and you're OK with that, you may not receive any real benefit by increasing it to 30'. Of course wet snow is another story.

If you choose to install an impeller seal, Make Sure the Impeller Bearing is 100% Tight. A Sloppy Bearing will wear out the Seal in No Time.

I installed peddles on my Honda a couple of years ago, the stock impeller to housing clearance was 1/8~1/4", after using the set up for one season I took them off as i didnt notice any change in performance.

I do about 15 drives per storm. I put impeller kit on a blower as soon as I buy it. I find that even a fairly tight fit is improved for blowing slush without clogging. Here in the Northeast snow to rain events are all too common. 10 inch turn to heavy rain is no fun at all. You can pump even really sloppy stuff but keep your auger belt in good shape, slush is hard on belts. In my case I wont run without the kit installed.

IMHO, it will improve on any unit (just on some would be a lot more evident than others) as the impeller properly installed closes the gap down to nearly zero. In slushy snow conditions is where it'll be noticed the most though.
Being an inexpensive upgrade I'd do it on a use machine.
