Its a quick and easy mod, and ive had this vacuum cap for about 1.5 years now, sounds great (well drowned out with my headers now) but havent noticed a drop in power.
Ive had my car tuned by the same tuner/dyno as a few other ISF's with almost identical mods (just different brand exhausts) and we all put out similar power so curious about the negatives of this mod, cheers.

Hi, do you have any links / forums discussions about this as id like to have a read. I havent come across any posts about this mod being negative. Ill revert back if it is.

Well the positive is that it takes all of 5 seconds to revert back which ill try given my headers / exhaust drowns out any kind of intake noise anyway lol.

Well took the vacuum cap off, reverted back to standard and drove for a good 1hr home, in traffic, hard acceleration from the lights, top end pulls on a motorway and as soon as got home i put the vacuum cap back on lol.
Sounded better with the mod and surprisingly felt like sharper throttle response with the vacuum cap on.
Didnt like how it drove for that 1hr in comparison, perhaps because my car was tuned with with the small mod, who knows.
Perhaps a dyno may suggest otherwisse but my backside dyno definitely likes it with the vacuum cap on
