                                                and .... from the NGK site  :

Modifications that will typically not require specialized plugs (in most
cases the factory installed plug will be more than adequate) include adding a
free-flowing air filter, headers, mufflers and rear-end gears. Basically, any
modification that does not alter the overall compression ratio will not
usually necessitate changing plug types or heat ranges. Such minor
modifications will not significantly increase the amount of heat in the
combustion chamber, hence, a plug change is probably not warranted.

However, when compression is raised, along with the added power comes added
heat. Since spark plugs must remove heat and a modified engine makes more
heat, the spark plug must remove more heat. A colder heat range spark plug
must be selected and plug gaps should be adjusted smaller to ensure proper
ignitability in this denser air/fuel mixture.

Typically, for every 75-100 hp you add, you should go one step colder on the
spark plug's heat range. A hotter heat range is not usually recommended
except when severe oil or fuel fouling is occurring.

I searched the Bosch usa site for F5DPOR which returned zero results.  he he
(useful, not)

Sounds like there may be a better plug. (At least for higher hp cars)
