I'm about to change my spark plugs/coils and I have used Bosch FR6 LDC's #7410 for the past 6 years with no problems. When I made my recent parts order I made a mistake and I got Bosch FGR7DDP's #4303 instead. Has anyone used these or are they correct for a 996T?

Thanks in advance!

 

if you have a 996tt you can use Bosch FR6 DPP322 / a Bosch 7 is not correct for this engine

 

Thanks for the info. I thought it was suggested to run a colder plug for a tuned engine? Do platinum plugs work okay for this engine?

 

one step colder with ngk is from 6 to 7, but with bosch from 6 to 5....

a gt2rs has oem "fr6 322dpp" over this powerlevel you need 1 step colder bosch 5 or ngk 7

the fr6 322dpp works fine with this engine..another route is denso ik or vk 20 /one step colder is 22

hope that helps and sorry my english is not the best....

 

Thanks for clearing that up for me! Ruf Germany actually suggested I run the regular Beru's or try NGK...Do you think that would be the BKR7E's?

 

Winngt2 is right on the money.......I would personally stay away from the Beru's from everything I heard about them and how much better the other plugs are over those...

 

I can't really help you on this one but seeing how cheap the FR6 are, i wouldn't take any chance and order a set and get rid of the other set.

 

NGK Katalog says: 996tt BCPR7ET

 

BKR7ES dont stay long...you need with a single electrode platin or iridium
