Your original post is not word for word correct.  The Platin is know as a 
"Platin" not platinum as you wish to keep calling it.  Get over it your 
wrong.  Bzzztttttt Trigger finger on the buzzer, yer out.....  

Yer original post...............

Just because your german/english dictionary says that does'nt mean that's 
what Bosch is saying.  Ohio in Japanese means, 1) It is Early, 2) Good 
Morning, 3) Good Day  4) Welcome to the Sun and 5) A State in America. 
Which one did I mean?  It's all in context....  I could have been 
refering to the State, or it could have been a wakeup call (Mosh Mosh, 
Ohio Guzimus (Phoenitic Japanese spelling))......

As for the common box big time BBBBZZZZZZZTTTTTTTTTTTTttttttttt.  You've 
never seen a platin have you?  Big time diff box, Diff size, color and 
wording printed on the box.  Go to the dealer and get one, and compare it 
to the platinum.......
As for calling it by it's "f***ing part number" we are.... go to the 
dealer or any parts house and ask for a "Platin" for the S4 or early 911 
you will get a F5DPOR or 6,7 and maybe 4 heat range Depending on app. but 
it will still be a "DPOR" Platin plug along with a big bill and a large 
smile on the face of the parts guy.  Don't belive me call Jim at Imparts 
(they have a 800 #) and ask for a Platin...... you will get a Platin, not 
platinum.

Here is Scotts autopsey's of the Platin and Platinum plugs...

F5DPOR - Bosch PLATIN

A totally different animal than the Platinums.  The electrode stands .140 
OUT of the closest ceramic, and the ceramic is thick (.050" thick) where 
is starts, not a coating (that I could scrape off the Platinums all the 
way to top of the thread on inside), need the dremel here......  
Advantages:  side fire plug, platinum tip protrudes .060 out of 
electrode, and grounding tip has a .040 "wear tip" on it.  Looks like a 
tough one to foul, and an easy one to pull, adjust and replace (and is, 
BTDT) for the 30k miles Bosch claims they are good for on an S4.  Good 
heat ranges available from 5,6,7(BTDT) I heard there is a 4, but can't 
say for sure.  Disadvantages:  Price, price price....  at 15 bucks 
(discount) they are a chunk of change.  Need to take off or modify the 
"resistor shields" from the stock pug wires..... Have seen, or more 
specifically, heard no ills from this procedure, including CB reception.  
Just don't get enough drooling and "look cool" expressions from the 
crowd.  Did I say they were expensive?

WR7DP - Platinum

Plug tip coated in ceramic except for .035" dia. platin spot at the very 
tip.  The tip is conical, but has no protruding tip (see platin) to 
measure.  Stripped ceramic away, no surprises the very tip is all that 
shows to the "ground tip".  No visible wear, but not sure of mileage on 
these pups either, my guess is that they are new, no pits even under 
ground tip.  Advantage here is price....  At 1.50 at trak auto and Kmart 
availability, it's no wonder it sells as well as it does.  Disadvantages: 
 Many. 1) a .035 spot (and that's used BTW) on a ceramic tip is hardly an 
optimum sparker, prone to fouling (esp with 4 mikunis, BTDT), is a "top 
fire" plug, and is known to most tweekers, Ned and others included, as a 
no-no, go with the cheaper coppers, cuz of the tiny electrode fire spot.  
On a tweeked car, has a common propensity to "blow out" the spark at high 
rpm and "spirited" driving.  Impossible to find a 6 or < heat range on 
this plug.  Ceramic barrier is only a coating from tip to top of threads 
inside plug.


Motoring along with PLATINS.......


Later!
