[s-cars] Which spark plugs

[Scott Justusson]

Er, ok add me to the list of those *not* using FD5POR *ever* again, because when I had my shop, I have seen too many fail from the box, blow a pin hole in the ceramic and or just lose the electrode all together on high boost.  I had really good luck with NGK Iridiums for a while, but have recently just been content with a plain old Porsche Turbo app triple copper plug.

FYI, that FD5 is supposed to have a 25k service interval in a stock 20vt engine, so beyond 30k (IME) you are asking for coil pack issues from a resistance problem.  I know I am not the exception to the opin that the FD5POR is hardly first prize at the spark plug county fair.  Bet you won't find m-any I5 tuners using that plug.  Lose and electrode once, you won't swear *by* them ever again.

Just sayin

7 x 20vt engines = 0 x FD5POR equipped

If you are operating the car with the stock turbo and stock or  
modified chip sets producing ~ 21psi boost, there have been no  
reported problems with the Bosch F5DPOR plugs.  These plugs cost more,  
but there are aftermarket sellers online that have them for ~$10 ea.   
These plugs also last for at least 30K miles.  These are what I use in  
my cars RS2 and MTM 1+ and my neighbors 2 UrS6 vehicles, 95.5 and 97  
tuned with MTM 1+ chip sets.

This must be more than just a "rumor".  You must have specific  
information if you feel compelled to ask.  Anyone who is making  
recommendations to you should stand by them with specifics and their  
name.  That's  the way we operate.

This spark plug thing is much like the oil or tire question.  You will  
get about as many solid recommendations as there are choices.
