BCPR7ES is for the 1999 saab 93 2.0l turbo, however they fit perfectly in the H22. A lot of people have had great experiences with them with a boosted H22 application. POSSIBLE benefits from running the BCPR7ES:
No V groove that can contribute to detonation
Plug does not extend as far into the combustion chamber as the stock ZFR plugs
Copper is more conductive than platinum and iridium (platinum and iridium is used for longevity).
1 step colder, the 7 denotes the heat range, the higher the number, the cooler the plug.
(This is just stuff I've read over time, theres more on the web if you google about Vgroove and depth of the plug)
Your one step colder stock plugs (or the copper equivalent that some guys like to run): ZFR7F-11

There are probably countless threads about iridium... they last long, they conduct fairly well. Their longevity/strength allows the manufacturer to run a "sharper" tip since it is able to withstand the pressure/heat from combustion. However they cost a buttload more and are less conductive than copper. If you change your copper plugs frequently, you will spend less and also benefit from having several "fresh set of plugs" over the same course of time.
BTW, since you're running FI, you want to MAKE SURE you gap your plugs correctly and inspect them frequently (you are looking for signs of minor/small scale detonation, shows on plugs as little aluminum specs on the porcelain). You want a gap of about .03", or about 1mm, which the BCPR7ES are gapped at straight out of the box. And take care when adjusting/checking the gap and use a wire type gapper, not the coin type (the $1 gappers from autozone), they are terribly innacurate.
Hope i've helped (btw,
www.sparkplugs.com for the BCPR7ES or call up local autozones/pepboys as they are sometimes hard to come by, the stock number is 3330).
