TR6s gapped at .035 here also..

 

any differance on the gap for an LQ9?

 

i do tr6s just like everyone else but step up the the 7's(br7ef) when i get over 10psi and even go another step colder when/if i think the boost is going to get into the upper teens.

 

sorry to thread jack but... what is the main diff. between an NGK FR-5 and TR6?

 

Did you mean TR55?

Here are some specs..


i found a FR-5:

14mm Thread
19mm (3/4") Reach
5/8" (16mm) Hex Size
Gasket Seat
Resistor, Solid Terminal, Projected Tip, V-Power (V-Grooved Centere Electrode)
.039" (0.9906mm) Gap



TR55:

14mm Thread
18mm (.708") Reach
5/8" (16mm) Hex Size
Tapered Seat, Resistor, Removable Terminal, Projected Tip, V-Power (V-Grooved Centere Electrode)
.059" (1.4986mm) Gap


TR6:

14mm Thread
18mm (.708") Reach
5/8" (16mm) Hex Size
Tapered Seat, Resistor, Removable Terminal, Projected Tip, V-Power (V-Grooved Centere Electrode)
.039" (0.9906mm) Gap

 

i did mean FR-5.. its what im running right now which is one heat range cooler than stock for me. was wondering if a TR6 plug would work better for me when i begin my remote turbo set up
thanks for the info!

 

Are these goin in your Dakota in your sig??

Onlything i noticed in those specs is they are 1mm longer... that could possibly pose a problem. Dunno tho..

 

yes, i wonder too. guess i need to do more research

 

I have TR5, TR6 and TR7's on hand. Looks as those as the range gets colder the reach gets shorter.
