Yeh tried those Forums with no luck. Most guys over there track their cars and use much colder heat ranges than I want to run in my daily street car.

I figure most of you guys who drive 993TT/996TT's drive these on the street daily and would have better experience running warmer plugs which are also suitable for the power levels in the 500-600 range

I've just changed up from W3CS to FR5DTC's and will see how they perform.

 

My 94 3.6T w/EFI uses the same FR6 ldc and runs fine.

Hi Elliot. How much boost does your 94 3.6T run? Are you running those plugs on the track as well as street? Thanks for your input!

 

I ran them on the track and street with the CIS sytem @1.1 bar worked fine.
AFR went lean on top
I'm still in fine tunning mode with The EFI @ 1 bar 486Rwhp but it is a little too rich . I may take it to LRP for a DE on Saturday to see how it goes.

Thanks for the feedback. If the FR6's are OK @ 1.1bar, then the FR5's should be OK @ 1.25bar, which is what I run I guess I just need to keep an eye on the plugs every few days to make sure they look OK.
